Reactions between hexanuclear manganese pivalate with lanthanide salts (chlorides or nitrates), in the presence of potassium hydroxide, 2-pyridylmethanol and sodium azide leads to formation of a new family of hexaheteronuclear manganese–lanthanide clusters.4.AbstractTwo novel metal–organic frameworks of [M3(ptz)2(N3)4(H2O)2] (M = Zn(1), Cd(2)) (ptz =5-(4-pyridyl)tetrazolate) have been prepared hydro(solvo)thermally by reactions of 4-cyanopyridine and excess NaN3 in the presence of zinc and cadmium chloride, respectively. The overall structure motif of complexes 1 and 2 show pillared layered frameworks and feature an unprecedented 3-nodal network with (3,5,6)-connectivity. The layer is of particular interest as it is constructed by μ1,1–N3− and μ1,1,3–N3−bridging modes, simultaneously. Furthermore, the solid fluorescent properties and TGA were studied.5. AbstractStructural characterization of a new self assembled coordination polymer of Cu II, hexamine (hmt) and benzoate (OBz), [Cu4(OBz)8(hmt)]n (1), reveals that it is a cubic non-interpenetrating diamondoid network formed by the coordination of the μ4-hmt ligand to a linear [Cu2(OBz)4] spacer. The magnetic study reveals that the Cu(II) ions are antiferromagnetically coupled (J = − 323.5 cm−1) through the syn–syn carboxylate bridges.6. AbstractSimple PET chemosensors based on anthracene show a selective turn-on fluorescence sensing for Cu2+. The flexible receptor is favorable for turn-on sensing due to chelation enhanced fluorescence. Interestingly, the turn-on fluorescence sensing for Cu2+ is hardly disturbed by the competitive cations and other highly prevalent species in biological and environmental systems, implying a potential in the biological and environmental applications.Metallacyclodimeric complex of [(Me4en)Pd(L)]2(PF6)4 (Me4en = N,N,N′,N′-tetramethylethylenediamine; L = 1,3-bis(4-pyridyl)tetramethyldisiloxane) is a sensitive container for dioxane via appropriate size effect. The equilibrium between the “included” and “free” dioxane species has been monitored by temperature-dependent 1H NMR spectra.8. AbstractAn unprecedented (ethanol)4 cluster is observed in a photoluminescent silver(I) coordination polymer host, [Ag2(dmt)2(nda)·2EtOH]n (1, dmt = 2,4-diamino-6-methyl-1,3,5-triazine, H2nda =naphthalene-1,4-dicarboxylic acid, EtOH = ethanol). In 1, two pairs of symmetry-related ethanol molecules are hydrogen bonded with each other by OH⋯O hydrogen bonds to form a R44(8) hydrogen bond motif where all the ethanol molecules are proton acceptor and proton donor at the same time. The thermal stability and luminescent behavior of 1 were also discussed.9. AbstractA new 3D sandwich-type MOF named [Zn3(bptc)(H2O)4]·C2H5OH·2H2O (1) (H4bptc =biphenyl-2,5,2',5'-tetracarboxylic acid) was obtained by solvothermal reaction, which represents a rare trinodal (3, 4, 10)-connected topology network. Moreover, the thermal stability, UV–vis absorption spectra and photoluminescent properties of 1 have been investigated as well.10. AbstractThe synthesis and characterization of novel metal-free and cobalt phthalocyanine, peripherally symmetrically derived from2,3,6,7,10,11,13,14-octahydro-5H,9H-4,12-(propanothiopropano)-1,8,15,23,4,12-benzotetrathiodiazacyc loheptadecane-17,18-dicarbonitrile (4) which was prepared by the reaction of1,9-diaza-5,13-dithiocyclohexadecane (3) and 1,2-bis(2-iodoethylmercapto)-4,5-dicyanobenzene (2) wascarried out. The novel compounds were characterized by using elemental analysis, 1H, 13C NMR, IR,UV–vis and MS techniques.11. AbstractA novel cationic dinuclear ruthenium complex [RuCl(HL)(TFTPP)]2 (H2L =2,6-bis(5-phenyl-1H-pyrazol-3-yl)pyridine; TFTPP = tri(p-trifluoromethylphenyl)phosphine) has been synthesized and characterized by 31P{1H} NMR, 1H NMR, elemental analysis and X-ray crystallography. This complex is the first cationic dinuclear ruthenium complex bearing N4 ligand characterized by single crystal X-ray analysis. It exhibits good catalytic activity for the transfer hydrogenation of ketones in refluxing 2-propanol.12. AbstractThree new metal-organic coordination polymers, [Mn(4,4′-bpy)(H2BTCA)(H2O)2](4,4′-bpy) (1),[Na2Co(BTCA)(OXA)]·3H2O (2) and [Na2Co(BTCA)(H2O)2] (3), (H4BTCA =benzene-1,2,4,5-tetracarboxylic acid, H2OXA = oxalic acid) have been synthesized, which are characterized by elemental analysis, infrared spectrum and x-ray crystal diffraction. Complex 1 possesses a 3D polymeric structure, which is comprised of (4,4)-layers. Hydrogen bonds play a dominant role in the construction of the final 3D supramolecule. 1D channels are observed in complex 2, which can be ascribed to pillared-layer motifs.13. AbstractTwo 2-(2-benzimidazolyl)-6-methylpyridine (Hbmp) copper(I) complexes bearing PPh3 and1,4-bis(diphenylphosphino)butane (dppb), namely, [Cu(Hbmp)(PPh3)2](ClO4) (1) and[Cu(Hbmp)(dppb)](ClO4) (2), have been synthesized. X-ray diffraction analysis reveals that the most significant influence of the phosphine ligands on the structures is on the P–Cu–P bond angle. Both two Cu(I) complexes exhibit a weak low-energy absorption at 360–450 nm, ascribed to the Cu(I) to Hbmp metal-to-ligand charge-transfer (MLCT) transition, perhaps mixed with some ILCT character inside Hbmp.The room-temperature luminescences are observed for 1 and 2, both in solution and in the solid state, which originate from the MLCT excited states and vary markedly with the phosphine ligands.14. AbstractA new self-assembly gadolinium(III)–iron(II) complex (Gd2Fe) was synthesized and characterized. Relaxivity studies showed that complex Gd2Fe exhibited higher relaxation efficiency compared with the clinically used Gd-DTPA. In vitro MR images on a 0.5 T magnetic field exhibited a remarkable enhancement of signal contrast for Gd2Fe than Gd-DTPA. The results indicated that Gd2Fe could serve as a potential MRI contrast agent.15. AbstractThe reaction of AgClO4·6H2O with (+/−)-trans-epoxysuccinic acid (H2tes) in the presence of2,6-dimethylpyridine afforded a three-dimensional (3-D) Ag I coordination polymer [Ag2(tes)]∞ (1), which exhibits an unusual 5-connected self-penetrating (44·66)2 topological net (tes =(+/−)-trans-epoxysuccinate). Comparison of the structural differences with our relevant finding, atwo-dimensional (2-D) (4,8)-connected (45·6)2(418·610) coordination polymer [Ag4(ces)2]∞ (S1) (ces =cis-epoxysuccinate), suggests that the carboxyl configuration on the ternary ring backbone of H2tes or H2ces ligand plays an important role in the construction of coordination networks.16. AbstractAn unusual three-dimensional (3D) pillared-layer 3d–4f (Cu+–Sm3+) heterometallic coordination polymer, {Sm2Cu7Br6(IN)7(H2O)5·3H2O}n (1) (HIN = isonicotinic acid), has been successfully synthesized by hydrothermal reaction of Sm2O3, CuBr2, HIN, HClO4 and H2O, and characterized by elemental analyses, IR, PXRD, and single-crystal X-ray diffraction. The structure determination reveals that 1 possesses 3D heterometallic framework constructed upon unprecedented [Cu7Br6]n n+ inorganic layers linked by dimeric Sm2(IN)6 pillars. Additionally, the thermogravimetric analysis and luminescent property of 1 were investigated and discussed.17. AbstractA novel double-Dawson-anion-templated, triangular trinuclear Cu-trz unit-based metal–organic framework [Cu II8(trz)6(μ3-O)2(H2O)12][P2W18O62]·4H2O (1) (Htrz = 1,2,4-triazole), has been hydrothermally synthesized and characterized by routine methods. Compound 1 is the first example of the Cu3-triad triangular unit-based three-dimensional (3D) metal–organic framework templated by double [P2W18O62]6−polyoxoanions. Furthermore, the electrochemical property of compound 1 has been studied.18. AbstractA new three-dimensional terbium-carboxylate framework [Tb4L3(H2O)9]·7H2O (1) [(H4L =4,4′-(hexafluoroisopropylidene)diphthalic acid)] has been hydrothermally synthesized and structurally characterized. The framework contains Tb2 and Tb4 clusters, and exhibits an unprecedented 4-nodal (3,4,5,8)-connected topology. In addition, the thermogravimetric analysis, luminescent and magnetic properties were investigated.19. AbstractThis paper reports two alkaline-earth metal phosphonates with formulae M(4-cppH2)2 [M = Sr (1), Ba (2); 4-cppH3 = 4-carboxylphenylphosphonic acid]. Compound 1 shows a chain structure made up ofedge-sharing {SrO8} polyhedra and {PO3C} tetrahedra. While in compound 2, the edge-sharing {BaO8} polyhedra are connected by the {PO3C} tetrahedra to form a two-dimensional inorganic layer. Neighboring chains in 1 or layers in 2 are cross-linked by hydrogen bond interactions between the protonated carboxylate groups, resulting in three-dimensional supramolecular structures. The magnesium alloys coated with 1 or 2 films show significantly improved anti-corrosion behaviors compared to the bare substrate.20. AbstractA novel 3D inorganic–organic hybrid compound {[Cu3(en)(TTHA)(H2O)42O}n(1) (TTHA =1,3,5-triazine-2,4,6-triamine hexaacetic acid; en = ethylenediamine) has been synthesized andcharacterized. Topological analysis shows that the compound is a new 3,10-connected 2-nodal net with point symbol (418.624.83)(43)2, further simplification of the structure by merging two 3-connected nodes and one 10-connected node together gives a rare uninodal 8-connected hex net, we conclude that the2-nodal net found in the network is a hex-originated supernet. TG, IR, PXRD and photoluminescent spectra of the compound 1 are investigated.21. AbstractUnder hydrothermal conditions, Sm(NO3)3·6H2O reacts with N-(2-Hydroxyethyl)iminodiacetic acid(H3heidi), oxalic acid (H2Ox), in the presence of NiCl2·6H2O and NaOH, producing a novel two dimensional coordination polymer with the empirical formula of Na[Sm(Hheidi)(Ox)]·2H2O (1). X-ray diffraction analyses show that 1 crystallizes in the orthorhombic system, P na21 space group, a =25.9008(19) Å, b = 6.2593(5) Å, c = 8.7624(6) Å, in which the network of SmNO8 and oxalate units forms an extended two dimensional layered structure. To the best of our knowledge, 1 represents the first structurally characterized lanthanide complex containing H3heidi ligand. The variable-temperature magnetic property of 1 has been investigated and the results of magnetic determination suggest the existence of a weak antiferromagnetic coupling between the samarium ions.22. AbstractHeating [WO2(S2CNBu i2)2] with a slight excess of ArNCO (Ar = Ph, p-tolyl) results in the rapid formation of imido-ureato complexes [W(NAr){κ2-ArNC(O)NAr}(S2CNBu i2)2], a transformation believed to occur via the bis(imido) intermediates [W(NAr)2(S2CNBu i2)2]. The ureato ligand is easily removed (as the urea) upon addition of gaseous HCl to afford the dichloride [W(NAr)Cl2(S2CNBu i2)2]. While bis(imido) complexes are unavailable from the direct reaction of isocyanates (or amines) with [WO2(S2CNBu i2)2], they can be prepared upon addition of dithiocarbamate salts to [W(NBu t)2(NHBu t)2] addition of two equivalents of [NH2Bu i2][Bu i2NCS2] affording [W(NBu t)2(S2CNBu i2)2] in which both imido groups are linear.23. AbstractA new neutral dimeric cyclometalated iridium complex containing bridging thiocyanate ligands,[{Ir(μ-SCN)(pqcm)2}2] (1, pqcmH = 2-phenyl-quinoline-4- carboxylic acid methyl ester), has been synthesized and structurally characterized. The photoluminescence (PL) spectrum of 1 shows emission maximum at 638 nm with a lifetime of 0.11 μs and the PL quantum yield is c. The phosphorescence behaviours of 1 towards different solvents and metal ions were also investigated and the strong phosphorescence quenching by acetonitrile and two equivalents of Hg2+, Cu2+ and Ag+ ions were observed.24. AbstractIonothermal reaction of isophthalate (H2ip), and colbolt(II) nitrate under 1-ethly-3-methylimidazolium bromide (EMimBr) as solvent leads to a novel three dimensional metal–organic framework(EMim)2[Co3(ip)4] (1). It can be described as an eight-connected CsCl-type net (42464) utilizing trinuclear Co(II) clusters as eight-connected nodes and ip ligands as linkers. The imidazolium cation [EMim]+ of the ionic liquid acting as charge-compensating agents has interactions with the framework. The magnetic properties studies show ferrimagnetic behavior for 1.25. AbstractUsing the deprotection–realkylation methodology, a new electroactive tetrathiafulvalene-based bipyridine ligand,5-[{2-[4,5-Bis(methylthio)-1,3-dithiol-2-ylidene]-5-(methylthio)-1,3-dithiol-4-yl}thio]-methyl-2,2′-bipyridine (L), has been synthesized. Reactions of the above ligand with Re(CO)5Br or Re(CO)5Cl afford the corresponding tricarbonyl rhenium(I) complexes ReL(CO)3X (X = Br, 1; X = Cl, 2), respectively. Crystal structures of 1 and 2 have been described. The absorption properties of these new compounds have been studied. Electrochemical measurements have been performed and TTF/TTF+•/TTF2+ redox processes are observed.26. AbstractThree carbon-bridged bis(phenolate) neodymium complexes, [(MBMP)2Nd(μ3–Cl)Li(THF)2Li(THF)] (1), [(MBBP)2Nd(μ3-Cl)Li(THF)2Li(THF)] (2) and [(THF)2Nd(EDBP)2Li(THF)] (3) have been synthesized by one-pot reaction of NdCl3 and LiCH2SiMe3with 6,6′-methylenebis(2-tert-butyl-4-methylphenol)(MBMP-H2), 6,6′-methylenebis(2,4-di-tert-butylphenol) (MBBP-H2) or 6,6′-(ethane-1,1-diyl)bis(2,4-di-tert-butylphenol) (EDBP-H2), respectively, in a molar ratio of 1:4:2. The definitive structures of complexes 2 and 3 were determined by X-ray diffraction studies. Experimental results show that 1–3 efficiently initiate the ring-openin g polymerization (ROP) of ε-caprolactone and ROP of L-lactide.27. AbstractA 3D metal-organic framework {[Cd2(TZ)3(BDC)]·5H2O}n (1·5nH2O) (HTZ = 1H-tetrazole, H2BDC =1,4-benzenedicarboxylic acid), has been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction. The phase purity was confirmed by powder X-ray diffraction (PXRD), and the stability was identified by thermal gravimetric analysis (TG) and variable-temperature powder X-ray diffraction (VT-PXRD). The result of the single-crystal X-ray diffraction analysis indicates that 1 is a novel 3D microporous metal-organic framework constructed from Cd(II) metal centers and mixed linkers of TZ−anions and BDC2− anions. Photoluminescent measurement elucidates that 1 displays a strong and broad emission peak at 423 nm, which suggests that 1 may be a potential purple-light material.28. AbstractTwo inorganic–organic hybrids, (MPDA)2n(Pb3I10)n (MPDA = p-Me3NC6H4NMe3) (1) and(H2EPDA)n(Pb2I6)n·2n H2O (H2EPDA = p-Et2NHC6H4NHEt2) (2), have been solvothermally synthesized using p-phenylenediamine (PDA) as a precursor. Their iodoplumbate ions all show 1-D chain structures, but differ in interlinkage modes of [PbI6] octahedra: the former is both face- and edge-sharing, while the latter is face-sharing. The chain-like structure in 1 was reported only once in the literature. The results of optical absorption spectra and theoretical calculations for compounds PbI2 and 1–2 reveal a quantum confinement effect. Photoluminescent analyses show that they all exhibit blue emissions upon UV irradiation, which mainly originate from charge transfer from iodine atoms to ammoniums.29. AbstractPlatinum(II) complexes, [Pt(PDTC)(H2O)Cl] and [Pt(PDTC)(DMSO)Cl] (1) (PDTC = pyrrolidinedithiocarbamate) have been prepared and characterized by IR, NMR and X-ray crystallographic methods. In the crystal structure of 1 the central platinum atom is coordinated to two sulfur atoms of PDTC, one sulfur atom of DMSO and one chloride ion adopting a square planar geometry with the average cis and trans bond angles of 90.00° and 171.62° respectively. The 1H and 13C NMR spectral data indicate the coordination of both PDTC and DMSO to platinum(II). The title complex was screened for antimicrobial effects and the results show that it exhibits significant activity againstgram-negative bacteria (E. coli, P. aeruginosa), while the activities are moderate against molds (A. niger, P. citrinum) and yeasts (C. albicans, S. serevisaiae).30. AbstractA new stable mixed-ligand metal organic framework Zn2(tpt)2(2-atp)I21 (tpt = tris (4-pyridyl) triazine, 2-atp = 2-aminoterephthalate) with split channels has been synthesized and characterized. The nitrogen containing ligands tpt and 2-atp are selected to create attractive basic sites for the catalyst. The Knoevenagel condensation between benzaldehyde and the active hydrogen compound (ethyl cyanoacetate or malononitrile) is carried out using compound 1 as solid basic catalytic support. The test results indicate that 1 is an efficient base catalyst with selective catalytic properties. It gives 37% and 99% yield respectively for the condensation products ethyl (E)-α-cyanocinnamate and2-benzylidenemalononitrile. TG data show that the solid catalyst sample is fairly thermally stable. The compound does not show any signs of decomposition until 420 °C. PXRD data support that the catalyst remains its crystalline and framework stability after the catalysis process. These characters make it easily to be regenerated for the next cycle.31. AbstractA heteroleptic nickel-bis-1,2-dithiolene ion–pair complex, [BzQl][Ni(dmit)(mnt)] (where BzQl+ =1-(benzyl)quinolinium; dmit2− = 2-thioxo-1,3-dithiole-4,5-dithiolate, mnt2− = maleonitriledithiolate), was synthesized and characterized structurally, which exhibited novel magnetic bistability. The compound crystallized in triclinic system with space group P-1. The anions and cations form alternating layered alignments, and the anionic layer is built by the irregularly heteroleptic [Ni(dmit)(mnt)]− chains, where theneighboring anions are connected via lateral-to-lateral S…S contacts of dmit2− ligands. The temperature dependences of magnetic susceptibility follow the S = ½ Heisenberg alternating linear-chain model in high-temperature phase and Curie–Weiss law in low-temperature phase.32. AbstractA novel two-dimensional (2D) Mn(II) coordination polymer [Mn(H2bdc)(DMA)2] (1; H2bdc = terephthalic acid; DMA = N,N′-dimethylacetamide) based on trinuclear manganese subunit has been solvothermally prepared and structurally characterized by single-crystal X-ray diffraction. Compound 1 exhibits a rare layered structure with 6-connected hxl topology constructed from the trinuclear Mn3(COO)6 units, and further stacking of layers leads to a 3D supramolecular framework. The thermalgravimetric behavior and magnetic property of 1 have been also investigated. The magnetic susceptibility measurements reveal that the compound exhibits antiferromagnetic coupling interactions.33. AbstractA new salicylaldehyde derivative 1, i.e. 5-chloro-3-(ethoxymethyl)-2-hydroxybenzaldehyde, has been prepared and structurally characterized. A novel dinuclear copper(II) complex of its air-oxidized product 2 has been successfully yielded from the in situ copper(II) ion catalysis and complexation. Additionally, another control experiment has been carried out by using 3,5-dibromo-2-hydroxybenzaldehyde as the starting material, and a similar mononuclear air oxidation copper(II) complex 3 is obtained, where3,5-dibromo-2-hydroxybenzaldehyde has also been in situ transformed to the divalent anion of3,5-dibromo-2-hydroxybenzoic acid.34. AbstractSelf-assembly of CdCl2 and 1,2,4-triazole under hydrothermal condition yields a novel three-dimensional coordination polymer, namely {[Cd8Cl4(Trz)12(H2O)]·2H2O}n (1) (Trz = 1,2,4-triazole). Single-crystal X-ray diffraction reveals that four of the five independent Cd centers are linked by two μ2-Cl and two μ3-Cl atoms to form novel heptanuclear [Cd7Cl4] clusters, which are connected by the bridging water molecules to generate an unprecedented 1D castellated inorganic chain. Furthermore, the fifth unique Cd centerand the castellated Cd–Cl–O chain are joint to each other via six different μ3-Trz ligands to give a 3D organic–inorganic hybrid framework of 1.。

篇一:英文版化学实验报告Title: Preparation of Fe scrap from waste(NH4)The purpose of the experimentLearn the method used scrap iron preparation of ferrous ammonium sulfate.Familiar with the water bath, filtered, and evaporated under reduced pressure and crystallization basic working.The experimental principle, the iron and sulfuric acid to generate reactive ferrous sulfate, ferrous sulfate and ammonium sulfate in an aqueous solution of equal molar interaction, becomes less soluble blue generate ferrous ammonium sulfate.Fe+H2SO4=FeSO4+H2 (gas)FeSO4+ (NH4)2SO4+6H2O=(NH4) Usually ferrous rocks are easily oxidized in air, but after the formation of relatively stable perfunctory, not to be oxidized.Experiment to use instruments, scales, constant temperature water bath, pumps, basins, cups, 10ml graduated cylinder, asbestos mesh, glass, tripod, alcohol lamp, funnel.Iron pieces to a solid pharmaceutical use, use of acid ammonium sulfate and 3mol / l of sulfuric acid, concentrated sulfuric acid.The experiment was divided into four steps.The first step Said iron powder 4g into a beaker and then 50ml10ml, 3mol / L H2SO4 was added to the same beaker. The second step will be the beaker is heated to no more bubbles, and then filtered hot and the filtrate was then filled in 100ml beaker. The third step, called 4g (NH4)2SO4, and the resultingammonium sulfate and of water to form a saturated solution, and then add it to the ferrous sulfate solution, adjusted with concentrated sulfuric acid to PH = 1. A fourth step, the third step the solution was heated in a water bath to the surface until the film is crystallized, it was slowly cooled andthen filtered under reduced pressure to stand finally dried, weighed and the yield was calculated. The results obtained bluish powderycrystals. Have this result we can calculate yield, starting with the first step we tried to know the amount of iron, should this wecan calculate the theoretical sulfate ferrous sulfate is , thenferrous sulfate obtained by thetheoretical value of ammonium. FeSO4+(NH4)2SO4+6H2O=FeSO4.(NH4) molX=m=XM=ⅹ392g/mol=Yield = the actual value of the formula is divided by the theoretical value by 100%.it will be calculated into the dataobtained in a yield of %.篇二:英文版化学实验报告The preparation of alkali type copper carbonateThe first:the experiment purposethe methods of alkali type copper carbonate prepared andprinciplethe design experiment to cultivate independent design abilityand chemical research thinkingThe second:the experimental principleThe solubility of Cu(OH)2and CuCO3 are similar, With Cu2(OH)2CO3 solid precipitation in the solution.2CuSO4+2Na2CO3+H2O==Cu2(OH)2CO3↓+2Na2SO4+CO2↑The third:the experimental stepspreparationDisposes mole of each litre acid sour coppers and sodiumcarbonate solution each 100 milliliters.feeding order and raw material compare the explorationAccording to 2:,2:2,2:,2: allocated proportion, is accepted after passing an examination the surface disposition acid sour copper and the sodium carbonate solution, joins in separately 8 test tubes,joins rapidly the sulfuric acid copper solutions in the sodium carbonate solution, vibrates about other constant temperature ten minutes as for 75 degrees Celsius water baths in, the inversion feeding order recreates one time, the observation has the precipitation speed, quantity how many and the color,discovers the optimum condition.explorationAccording to the above optimum condition, takes the acid sour copper solutions and the sodium carbonate solution separately under 50, 75 and 100 degrees Celsius responded that, discovers the optimum temperature.to 2, 3 step exploration optimum condition prepares the final product, and with the distilled water lavation, finally dries and calls heavily.(Enlarges ten times with conical flask to do)The fourth:the experimental itemsInstrument and material: The balance, the beaker, the glass rod, the Volumetric flask, the test tube, the filter flask,the Buchner funnel, the Erlenmeyer flaskChemicals: Copper carbonate, sodium sulfateThe fifth:the experimental resultthe step 2, the observation phenomenon optimum condition is equal to for the cupric sulfate compared to the sodium carbonate 2:, the feeding order for joins the sulfuric acid copper solutions to the sodium carbonate solution in.the step 3, the observation phenomenon optimum temperature is 75 degrees Celsiusto the copper sulfate solution than sodium carbonatesolution is 2:2. 4, ten times magnification, alkali type copper carbonate was zero point five grams, according to the reaction equation calculation yield.2CuSO4+2Na2CO3+H2O==Cu2(OH)2CO3↓+2Na2SO4+CO2↑2 1* X2/(*)=1/XX=M[Cu2(OH)2CO3]=*222=Productive rate:/*100%=45%The sixth : Questions1.

Example

We must therefore conclude that when the distance between the molecules is very small, there are forces of repulsion and that these forces increase rapidly as the distance between the molecules decrease.
An important structure that recurs in SEC is the use of relatives, for the reason that scientific writing tend to define or describe things, which requires the frequent using of adjectives, adjective clauses( clause or –ing).
