Therefore, adding chlorine to water is a crucial step in ensuring the safety and cleanliness of drinking water. 氯气被添加到水中以使其安全饮用,因为它是一种强氧化剂。氯可以杀死水中的细菌和病毒,从而防止水源性疾病的传播。因此,添加氯气是确保饮用水安全和卫生的关键步骤。
解析 We don't round it to a whole number because we want the number of the relative atomic mass of cholorine to be as precise as possible.We really care about the significant figures,so it's better if we get more digits. 结果一 题目 why is this the relative atomic mass of chlorine ...
The study is based on periodic density functional theory calculations carried out for the reaction between ethene and atomic oxygen on the Ag(111) surface, taken as a model catalyst, in the presence of coadsorbed halogens. It is found that the presence of co-adsorbed halogens significantly ...

The problem isn’t just a lack of toilets—it’s a lack of toilets that people want to use. The result: millions of deaths and disease-stunted lives.
Why Chlorine Should Be Banned Industrialized countries in the Northern Hemisphere, including but not limited to the United States as well as Europe, have discharged roughly 90 percent of CFCs currently in the atmosphere. These countries did put a ban on CFCs by 1996. It has been shown that th...
Well, on the molecular level, salt is actually made up of two different ions, 嗯,在分子层级上,盐其实是由两种不同的离子构成的, chlorine and sodium, that are organized like a brick wall. 氯离子和钠离子,它们就像砖墙一样被组合起来。 They show up to the dance as a big group in formation...
