I think a really cool aspect to that question is that pure H2O is not pure H2O due to the second law of thermodynamics, the one about entropy. Perfect order is impossible. Water naturally exists in a form where one molecule out of 10,000,000 spontaneously divides into a hydrogen ion and...
Yet H2 Sis acidic while H2O is neutral. This is because DA)Water is a highly associated compound B)Molecular mass of H2 S is more than that of H2O C)H2.S is gaseous under ordinary conditions while H2O is a liquid D)H-S bond is weaker than H-O bond. 相关知识点: 试题来源: ...
