We can’t remember clearly since when we started to take our mobiles to a dinner table. This happens a lot, especially when we eat out. Once a dish comes, instead of lifting our chopsticks, we take out our mobiles and click. Later, we post photos onto Weibo or Wechat, waiting to be “liked”. Then we check our mobiles from time to time during the meal, to see whether we get “liked” or not. We just cannot leave our mobiles for only a meal.   Does that sound familiar to you? Do you do that often? If not, how do you feel when others do that when having dinner with you?   A recent（7分）实验室用下图的装置将CO2和CO进行分离和干燥.已知a、b均为活塞，试回答： (1)甲装的是        溶液，乙装的是         溶液，分液漏斗中装的是             (2)当CO2与CO的混和气体通过该装置时，先分离得到的是                     ，活塞操作是             ；然后得到                ，活塞操作是          。
