2018年中考化学真题分类汇编溶液含解析
2018化学中考题分类汇编之溶液 1.（2018德州）右图是甲、乙、丙三种物质在水中的溶解度曲线。以下说法正确的是（C）A．t2℃时溶解度由大到小的顺序是乙>丙>甲 B．由t2℃降到t1℃析出晶体最多的是甲溶液 C．由t2℃降到t1℃丙溶液浓度一定不发生变化 D．甲乙丙三种物质溶解度都随温度升高而增大 解析：根据溶解度曲线图可以判断t2℃三种物质的溶解度是甲﹥乙﹥丙，A说法不正确；等质量的三种物质的饱和溶液温度由t2℃降到t1℃，析出晶体最多的是甲溶液，B说法不正确；温度降到丙的溶解度增大，所以丙的溶液由t2℃降到t1℃，一定不会析出晶体，所以溶液的浓度一定不会发生变化，C说法正确；丙物质的溶解度随温度的升高而减小，D说法不正确。 2.（2018梧州）右图是a、b、c三种物质的溶解度曲线，下列说法错误的是（） A．t2℃时，溶溶解度：a＝b＞c B．随温度的升高，c物质的溶解度减小 C．t3℃℃时，将30克a加入50克水中可以得到80克溶液 D．t1℃时，a的饱和溶液和c的饱和溶液的溶质质量分数相等 答案：C 解析：根据溶解度曲线判断t2℃时，溶溶解度：a＝b＞c；随温度的升高，c物质的溶解度减小；t3℃时，a的溶解度为50g，将30克a加入50克水中，最多溶解25克，可以得到75克溶液；t1℃时，a和c的溶解度相等，a的饱和溶液和c的饱和溶液的溶质质量分数相等。故选C。 3.（2018枣庄）溶解度是定量表示物质客解性的一种方法，图中给出了三种物质的溶解度曲线，下列说法不正确的是（） 保持健康心态，勇敢面对中考；合理饮食，合理睡眠；预祝金榜题名，万事如意！保持健康心态，勇敢面对中考；合理饮食，合理睡眠；预祝金榜题名，万事如意！
中考英语试卷英语阅读理解题分类汇编(及答案)
中考英语试卷英语阅读理解题分类汇编(及答案) 一、英语阅读理解专项练习试卷 1．阅读理解 According to a 2018 study from San Francisco State University, nearly 2. 4 billion people around the world used a smartphone in 2017. By the end of 2019, more than a third of the global population will be using a smartphone. However, smartphone technology can be a double-edged sword. On the one hand, it sends us unlimited amounts of information. On the other hand, using a smartphone may become an addiction. Erik Peper and Richard Harvey are both health education professors at San Francisco State university. They led the study. Peper explains that smartphone addiction forms connections in the brain that are similar to drug addiction. And these connections form slowly over time. Also, addiction to social media may affect our emotional state. The two professors asked 135 university students about their habit of smartphone use and their feelings. They found that students who used their phones the most reported higher levels of feeling lonely, depressed and anxious. Peper and Harvey do not blame users for their technology addiction. They believe it is the tech industry's desire to make more money that is to blame for the technology addiction. The researchers warm that workers in the technology industry know how to control our brains and turn us into addicts. But the researchers say that we can limit our brains to be less addicted to our phones and computers. Enk Peper suggests timing off our phones before we sleep or do something important. The researchers also suggest taking control of when and where you answer texts or emails. You do not need to answer them all. And you certainly don't need to answer them as soon as you get them. They also suggest putting limits on the time you spend on social media. If you want to catch up with friends on Facebook, set aside a small amount of time to it. You should focus on important tasks and do not allow technology to disturb you. （1）What can we infer from Paragraph 1? A. Smartphone use has become extremely common. B.
