①Since mid-September, 200.000 science popularization activities (科学普及活动) have been held in China. Many schools held activities by themselves. This autumn, many schools changed their science subjects to meet new technologies. And they tried to use new ways to make such classes more interesting.
②A teacher made a butterfly specimens (蝴蝶标本) with three of her students during a science popularization activity held at a primary school in Hangzhou on September 18.
③At a high-tech (高科技) show at a primary school, students were interested in a robot dog jumping and dancing. It even said hello and shook (握手) their hands. “I got to touch the robot dog, and it was so interesting. I will work hard and learn more about it,” said Mou Yuejia, a student at the primary school in Tonghai County, Yunnan Province. The show was part of an activity to popularize science and technology at schools, and exhibits about ecological protection (生态保护).
④Pouring (倾倒) water, oil and something else into a cup, Feng Jiaqi, a pupil at a primary school in Henan, made a scientific experiment like volcanic eruptions (火山爆发). “As the density (密度) of water is higher than oil, the two will be clearly parted, with oil on top of the water,” Feng explained. The school opened more science classes for its first-and second-grade students this school year.
⑤In Fujian Province, more than 300 university laboratories (实验室) and science and technology museums opened science classes for primary and middle school students. They planned much classes together with teachers.

【详解】(1)厨房中食醋的主要成分为醋酸,化学式为CH3COOH;
(2)中和反应是酸和碱反应生成盐和水,其中发生的中和反应为氢氧化镁和盐酸反应生成氯化镁和水,化学方程式为Mg(OH)2+2HCl=MgCl2+2H2O;此类反应的微观实质为在溶液中,氢离子与氢氧根离子反应生成水分子;
(3)氢氧化钠的俗称为火碱、烧碱、苛性钠;
(4)正常雨水的pH约为5.6,是因为二氧化碳和水反应生成碳酸。
15. 放热 一定有NaCl,可能有NaOH或HCl中的一种
【详解】用图甲装置探究氢氧化钠溶液与稀盐酸反应过程中溶液的温度变化,测得溶液温度随时间的变化如图乙所示。盐酸与氢氧化钠溶液反应生成氯化钠和水,该反应化学方程式:;由图乙可知,该反应属于放热反应;由图甲可知:烧杯内溶质是HCl、注射器内溶质是氢氧化钠,或者烧杯内溶质是氢氧化钠、注射器内溶质是HCl,盐酸与氢氧化钠溶液溶液反应有氯化钠生成,60s时溶液中一定有氯化钠,且注射器内溶质滴加到烧杯内过量,60s时溶液中溶质的成分为一定有NaCl,可能有NaOH或HCl中的一种。
