2020届高考化学人教版第二轮专题复习选择题强化训练:新型化学能源(含解析)

2020届高考化学人教版第二轮专题复习选择题强化训练新型化学能源1、液体燃料电池相比于气体燃料电池具有体积小等优点。
一种以液态肼(N2H4)为燃料的电池装置如图所示,该电池用空气中的氧气作为氧化剂,KOH溶液作为电解质溶液。
下列关于该电池的叙述正确的是( )A.b极发生氧化反应B.a极的反应式:N2H4+4OH--4e-===N2↑+4H2OC.放电时,电流从a极经过负载流向b极D.其中的离子交换膜需选用阳离子交换膜答案:B解析:燃料电池燃料(N2H4)在负极(a极)发生氧化反应:N2H4+4OH --4e-===N4H2O,O2在正极(b极)发生还原反应:O2+4e-+2↑+2H2O===4OH-,总反应为N2H4+O2===N2+2H2O,A项错误,B项正确;放电时电流由正极流向负极,C项错误;OH-在正极生成,移向负极消耗,所以离子交换膜应让OH-通过,故选用阴离子交换膜,D项错误。
2、如图是一种酸性燃料电池酒精检测仪,具有自动吹气流量监测与控制的功能,下列有关说法正确的是( )A.电流由呼气所在的铂电极流出B.H+通过质子交换膜流向氧气所在的铂电极C.电路中流过2mol电子时,消耗11.2 LO2D.该电池的负极反应为CH3CH2OH+3H2O-12e-===2CO2↑+12H+答案:B解析:呼气所在电极发生乙醇转化为醋酸的反应,故为负极,而电流由正极流出,A项错误;H+通过质子交换膜流向正极(氧气所在的铂电极),B项正确;正极反应为O2+4e-+4H+===2H2O,电路中流过2 mol电子时,消耗0.5 mol O2,在标准状况下体积为11.2 L,但题中未指明是否为标准状况,C项错误;该电池的负极反应为CH3CH2OH+H2O-4e-===CH3COOH+4H+,D项错误。
3.用FeS2纳米材料制成的高容量锂电池,电极分别是二硫化亚铁和金属锂,电解液是含锂盐的有机溶剂。

专题强化训练2(建议用时:40分钟)1.根据要求写两段话,每段话都要包含下面三个词语,不少于40个字。
明月白雪云层(1)描绘一种情景。
答:(2)表达一种感悟。
答:解析:描绘一种情景,首先要分析三个词语之间的内在联系,如由“明月”联想到“月色”,再由“月色”联想到“白雪”;然后把这些词语描绘成一幅画,语言表达要形象生动。
表达一种感悟,首先要把三个词语组合成一段能给人启示的话,然后把这种启示表述出来。
答案:(1)一轮明月穿过厚厚的云层,毫不吝啬地向大地挥洒它皎洁的月光。
大地像被镀上了一层银白色,灿若白雪。
(2)如果明月没有穿透云层的毅力,就没有灿若白雪的皎洁月光洒向大地。
人也如此,没有克服困难的毅力,就没有美好灿烂的明天。

”看到我牛饮而尽的样子,(2)妈妈对我笑了……听我倾诉完了委屈,妈妈轻轻拍拍我的前胸说:“被人误解在所难免,不过,男子汉要坚强乐观,没有什么能击倒我家小王子,妈妈相信你!”我不由得破涕为笑,见此情景,(3)妈妈也对我笑了……(1)(2)(3)答案:示例:(1)妈妈先是惊讶得睁圆了双眼,继而整张脸都笑了起来,灿烂得像花朵绽放,连眼角、皱纹里都漾满了深深浅浅的笑意,仿佛在说:“好样的,儿子,妈妈为你骄傲!”(2)妈妈对我莞尔一笑,微抿的嘴角轻扬出优美的弧度,微眯的眼睛里闪现着慈祥、疼爱的光芒,轻轻地说道:“瞧你那贪婪样,小心,别噎着。
”(3)妈妈居然调皮地、萌萌地对我眨眨眼,嘟嘟嘴,随即咧嘴而笑。
这微笑,暖暖的,如阳光温暖了我心底的寒冷。

2020届高三化学复习(二轮)冲刺专题强化练—— 化学平衡移动的图像分析

2020届届届届届届届届届届届届届届届届届届—— 届届届届届届届届届届届一、单选题(本大题共20小题,共40分)1.根据下列有关图象,说法正确的是()A. 由图①知,反应在T1、T3处达到平衡,且该反应的△H<0B. 图②中曲线表示反应2SO2(g)+O2(g)⇌2SO3(g),△H<0正、逆反应的平衡常数K随温度的变化C. 由图③知,反应在t6时,NH3体积分数最大,t3时采取降低反应温度的措施D. 图④中a、b曲线分别表示反应CH2=CH2(g)+H2(g)→CH3CH3(g)△H<0使用和未使用催化剂时,反应过程中的能量变化【答案】B【解析】解:A、由图Ⅰ知,反应在T1、T3处反应物和生成物的体积分数相等但反应不一定达到平衡,T2−T3升高温度,反应物体积分数增大,生成物体积分数减小,平衡向逆反应方向移动,所以正反应是放热反应,△H<0,故A错误;B、因反应为放热反应,则升高温度,平衡逆向移动,平衡后升温K(逆)会增大,而K(正)会减小,图象中变化与实际上的变化相符,故B正确;C、由图Ⅱ知,t2时刻正逆反应速率都增大且相等,改变的条件是加入催化剂,平衡不移动;t3时刻正逆反应速率都减小,且逆反应速率大于正反应速率,改变的条件是减小压强,平衡向逆反应方向移动;t5时刻正逆反应速率都增大,且逆反应速率大于正反应速率,改变的条件是升高温度,平衡向逆反应方向移动,所以反应在t1时,NH3体积分数最大,故C错误;D、图象中使用催化剂降低反应活化能,但反应是放热反应,反应物能量高,图象中表示的吸热反应,故D错误;故选:B。
A、反应物和生成物的体积分数相同时,反应不一定达到平衡状态,升高温度平衡向吸热反应方向移动;B、该反应为放热反应,温度升高,平衡向着逆向移动,K(逆)增大、K(正)减小;C、t1时刻正逆反应速率相等,反应达到平衡状态;t2时刻正逆反应速率都增大且相等,改变的条件是加入催化剂;t3时刻正逆反应速率都减小,且逆反应速率大于正反应速率,改变的条件是减小压强;t5时刻正逆反应速率都增大,且逆反应速率大于正反应速率,改变的条件是升高温度;D、图象中使用催化剂降低反应活化能,但反应是放热反应,反应物能量高.本题考查了化学反应能量变化,影响平衡因素的分析判断,图象分析方法和平衡移动原理的判断依据是解题关键,题目难度中等.2.一定温度下,在2L的密闭容器中发生反应:xA(g)+B(g)⇌2C(g)△H<0,A、C的物质的量随时间变化的关系如图。

Then he offered them a retest three days later. They thanked him and accepted his offer.9. the test day arrived,they went to the Dean. The Dean put them all in separate10. (room) for the test. They were fine with this since they had all studied hard. Then they saw the test. It had 2 questions.BOwing to the effect of traditional Chinese medicine and treatment, it becomes more and more popular now in the world. Traditional Chinese medicine originated in ancient and developed for 1. long time. It has collected various ways to treat 2. (differ) diseases. Traditional Chinese medicine pays attention 3. the balance of the body system. Once the body system balances, the disease 4. (disappear).

Beside, we can improve our health by exercise regularly in the morning. Second, it can also benefits our study because in the morning we can learn more quickly. Third, it can make us to plan our work for the day. Only without a proper plan can we work well. Early rising can allow us enough time to get ready for your work. So we say that those who always gets up late should make an effort to get up early.Ⅲ. 阅读理解One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem — inability to read.In the library, I found my way i nto the “Children's Room”. I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my “secret sharer”, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle.There on the book's cover was a beagle which looked identical(相同的) to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos: the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer.Under the shade of a brush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them.I never told my mother about my “miraculous(奇迹)” experience that summer, but she saw a slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words has held.1. The author's mother told him to borrow a book in order to .A. encourage him to do more walkingB. let him spend a meaningful summerC. help cure him of his reading problemD. make him learn more about weapons2. The book caught the author's eye because .A. it reminded him of his own dogB. he found its title easy to understandC. it contained pretty pictures of animalsD. he liked children's stories very much3. Why could the author manage to read the book through?A. He was forced by his mother to read it.B. He identified with (对某事有同感) the story in the book.C. The book told the story of his pet dog.D. The happy ending of the story attracted him.4. Which one could be the best title of the passage?A. My Passion for ReadingB. Mum's Strict OrderC. Reunion with My BeagleD. The Charm of a BookⅣ. 完形填空It was a cool October evening. Excitement and family members 1 the hall. I was only a 7-year-old girl, but I was the center of 2 .

I was concentrating so much 9 the huge smile on my face and holding my head up that I did not look 10 I was going. I missed my partner's box altogether and 11 . There I was standing on the stage floor when my classmates were on top of their boxes. I could hear giggles(咯咯笑) coming from the audience, and I felt the 12 rush to my face. I remembered my dance teacher had told us, “If you make a mistake, keep smiling so the audience will not 13 .
