What is Physical Organic Chemistry? Let's say you are working in a laboratory performing a chemical reaction using an organic molecule and oxygen. You realize that when both chemicals react together you get carbon dioxide, water, and heat. If there is an insufficient supply of oxygen then the...
Hydroxyl radicals, described as a "chemical scavenger ( 清洗剂) "by Science Direct, are important chemical compounds found in the atmosphere due to the reactive nature with other organic molecules ( 分子). Researchers previously understood that lightning could help to clean the atmosphere, but there...
