请阅读一篇短文，根据所提供的信息，完成下面的表格。 In the modern society, the traffic problem has become more and more serious, which has aroused(引起) wide public concern（关心）, especially in the rush hour , at some time or other, people would rather walk on the street than drive the car, and the line people waiting for the bus can be as long as 10 meters. Because a great number of office workers go to work and go off work at the same time, most private cars and buses are on the roads at the same time, which of course leads to traffic jams(交通堵塞). But how to solve it? As far as I’m concerned, for one thing, the government should build more roads to meet the needs of cars; for another, we should call for people to take a bus instead of driving their own cars. At times, we can also ride bikes to go to work or visit somewhere. Not only do we strengthen ourselves in this way, but also we protect the environment. In a word ,if all of us take actions to solve it, I believe there will not be a word named traffic jam . Information Card

、
、Fe2+和结晶水，设计了下列操作步骤：①取少量该化合物加热，发现试管口处有液体，该液体能使无水硫酸铜变蓝；②另取少量该化合物溶于水中，滴加少量的氯水，再加入KSCN溶液，有血红色出现；③取少量溶液于试管中，加入盐酸，没有现象，再加入BaCl2溶液，有白色沉淀生成；④取少量溶液于试管中，加入浓的NaOH溶液，微热有使湿润的红色石蕊试纸变蓝的气体产生，同时也有白色沉淀产生，该沉淀很快变成灰绿色沉淀。
