2019-2020学年安徽省宣城市三校(郎溪中学、宣城二中、广德中学)新高考化学模拟试卷含解析
C.温度T1、 ,Cl2的转化率约为33.3%
D.图乙中,线A表示正反应的平衡常数
【答案】C
【解析】
【详解】
A.ω增大,CH2=CHCH3的转化率增大,则φ减小,由上述分析可知:ω2>ω1,则ω1<1,故A错误;
B.该反应在反应前后气体分子数不变,根据图甲升高温度丙烯的体积分数增大,即升高温度平衡逆向移动,正反应放热,在恒容绝热装置中进行题述反应,体系内温度升高,根据PV=nRT,达到平衡时,装置内的气体压强将增大,故B错误;
C.此溶液可能含有Al3+,因为氢氧化铝不溶于弱碱,故错误;
D.发生Br2+SO2+2H2O=H2SO4+2HBr,体现SO2的还原性,故错误。
故选B。
5.国际计量大会第26届会议新修订了阿伏加德罗常数(NA=6.02214076×1023mol―1),并将于2019年5月20日正式生效。下列说法中正确的是
B.由反应物和产物的沸点数据可知,温度计1保持在90∼95℃,既可保证正丁醛及时蒸出,又可尽量避免其被进一步氧化,温度计2示数在76℃左右时,收集产物为正丁醛,故B不符合题意;
C.正丁醇能与钠反应,但粗正丁醛中含有水,水可以与钠反应,所以无法检验粗正丁醛中是否含有正丁醇,故C符合题意;
D.粗正丁醛中含有水、正丁醇,向粗正丁醛中加入CaCl2固体,过滤,可除去水,然后利用正丁醇与正丁醛的沸点差异进行蒸馏,从而得到纯正丁醛,故D不符合题意;
D.乙醇(乙酸):加入足量CaO后蒸馏
【答案】D
【解析】
【详解】
A.加入氯化钡引入新的杂质氯离子,应加入硝酸钡,故A错误;
B.由于不能确定乙烯的含量,则不能确定通入氢气的量,易混入氢气杂质,故B错误;
C.加入KI溶液,溴与KI反应生成碘单质,形成新的杂质酸钙,然后用蒸馏的方法可分离,故D正确;

Harris, who at present serves as a defensive back for her school's team in California, has signed a letter with the intention of playing for Central Methodist Universityin Missouri, making her one of just a handful of women to be offered a scholarship to play a sport historically mainly for men.“I had a coach who told me before that I would never get to the next level because I was a lot smaller and not as fast as the boys, so that moment taught me to never give up,” Harris tells CNN.In fact, compared to what she's been fighting off the field, facing sex discrimination(性别歧视)in the sport doesn't seem like such a big conundrum for Harris.The athlete was diagnosed(诊断)with ovarian cancer when she was 18. She felt better two years ago, yet not before losing half her body weight and having her dream of playing at the professional level nearly destroyed.“I always try to push myself every single day to let me go as far as I want to go,” she explains.During last month's Super Bowl, Harris appeared in a Toyota commercial(商业广告). In it, she worked on the field, fighting against players twice her size, lifting tires in the air, racing against the clock, as a voiceover(画外音)listed all of the things people had told the young star she couldn't do. It's inspiring, but for Harris, the attention she's receiving after making history is just more motivation to perform well.“In the end, you’ve got to push yourself," Harris says. “I’m going to focus on my goals. My final goal is to be excellent at a four-year university and become the first female NFL(National Football League) player. I know I can get there.”24.

But over the years, the world's deepest freshwater lake has been in the spotlight for an extreme sport.Each March, about 150 people from around the world sign up for the Baikal Ice Marathon. The 26-mile(41.84 kilometers)journey starts on the lake's pastern shore. In March, the ice is a meter thick and iron-hard. Runners cross this frozen surface, finishing on the western side of the lake.It's believed that Lake Baikal's beauty is incomparable. Known as the “blue eye of Siberia", Lake Baikal has particularly clear waters. This means that its ice is almost perfectly transparent(透明的). Seen from above, a runner on the ice looks as if he or she were jogging through space.The scenery might be beautiful, but strong winds blast(侵袭)across the lake and frostbite can occur within half an hour. Runners say the cold climate is what draws them and that running in such condition is a test of their limits."When you are in such an environment, you don't have cars around you, and you don't have the noise around. I think these extreme races push you to be alone.”Alicja Barahona, a 64-year-old runner from the US said.The place offers some strange and unique characteristics for this marathon. The finishing line is visible(可见的)from the start, but the endless white offers no progress markers. Tourists crowding the ice are mostly addicted to snapping selfies(自拍)and just ignore the runners.For runners, the absence of spectators(观众)makes the race more challenging, because it's lonely. They must fight with themselves. “You are alone on Baikal. It is your race. You are alone with yourself. All you need to do is to defeat yourself.” Veronique Messina, a French runner, told the Telegraph.28. What has kept Lake Baikal being a focus over the years?A. A famous Chinese singer.B.

The fact that the waters of Lake Baikal are clear.B. The belief that Lake Baikal is known for its waters.C. The reason why Lake Baikal is popular with runners.D. The popularity that clear waters in Lake Baikal enjoy.30. Why do runners sign up for the Baikal Ice Marathon?A. They prefer to get close to nature.B. They like competition with others.C. They want to draw much attention.D. They intend to test their own limits.31. Why is Veronique Messina mentioned at last?A. To prove the power of the runners for the Baikal Ice Marathon.B. To show that runners must fight against themselves in the Marathon.C. To explain that independence is important for marathon runners.D. To indicate the necessity of paying attention to marathon runners.DRobots performing tasks according to a predetermined set of instructions are nothing new. But robots able to learn how to cook by watching videos arc completely different. A group of researchers at the University of Maryland are looking for the approach.I f you have posted a video of your favorite recipe on the popular website YouTube, chances are that it will be used by a robot. University of Maryland professor Hyannis Alimonies, leader of the group, said, "There exists a large amount of video information on the Internet that our robots can make use of.”"At present, the videos are fed electronically,” said research scientist Cornelia Ferule, “At first, we took our own videos, our cameras looking at us doing the cooking,” she explained. "And, as the robot advanced, it reacted to good quality videos. And it will react to even lower quality home-made videos.”So far, the robot named Julia can make a simple salad by breaking each task into basic parts, such as grasping a spoon, bringing it to the bowl, stirring(搅拌)the salad and observing the results.But a robot is taught to understand a video though it can easily follow a fixed program. Alimonies believes predetermined instructions lack flexibility. “You have a system that is done just for this particular task. And so, it can't generalize,” Alimonies said. "You cannot take it and put it into different environments. It is not flexible.”He thinks one of the problems is how to make the robot understand and use what it learns during a certain task, the so-called feedback(反馈). Another problem, he says, will be theintroduction of language."I believe it will take quite some time before the robots are able to understand metaphorical(比喻的)language," he added. "Pit," he said, "we don't need that to create a new world where the robots will be working for us.”32. What are robots commonly thought to be able to do?A. Follow predetermined instructions.B. Use what they learn in any condition.C. Understand a video and react quickly.D. Perform different tasks at their own will.33. How does the author show robots' advances in cooking?A. By making comparisons.B. By offering an example.C. By listing some numbers.D. By analyzing the results.34. What does Hyannis Alimonies try to do in paragraph 5?A. Prove the disadvantages of predetermined instructions.B. Provide much more useful details of the robots' work.C. Give the reason for teaching a robot to understand a video.D. Tell a robot's ability to understand metaphorical language.35. What is the best title for the text?A. Robots Are Made Wonderful CooksB. Robots Talk About How to Cook FoodC. Robots Understand Videos on CookingD. Robots Learn to Cook by Watching Videos第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
