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。反馈 收藏
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 ...

Mel:Yeah. I think the project like this, it's turned out to be bigger and longer than I had initially thought, which is just blindness on my part. Of course, it was going to keep going. For me. hiring the PR firm and just having other folks be excited about it was so huge. And...
Write equations for the reaction of benzene with chlorine in the presence of an iron catalyst and for the analogous reaction with bromine.Predict product when HBr is added to the 1-butene.Write the electrophilic substitution reaction for butyraldehyde with ether (solvent) and bromine ...
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.
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...
Why the Level of Chlorine Is Not Going Down in Your Pool. For a swimming pool owner, the need to maintain the correct level of disinfectant in a pool's water is vital. Luckily, the most common pool disinfectant, chlorine, is relatively easy to manage. Ke
