希望可以详细一点..
[1]
Table salt naturally forms in tiny cubes with flat surfaces.Salt that is ground up very finely and examined under a microscope still appears as cubes,just very much smaller.Use the fact that salt is an ionic solid to explain how this happens.
[2]
Candle wax is composed partly of C18H38.The covalent bonds between the atoms in these molecules are extremely strong.Yet wax is soft and has a low melting point.Use the fact that wax is a molecular solid to explain why this is the case.

第一题是说氯化钠晶体是一个立方体,这是由于微观上氯离子和钠离子排成一个立方体的结构,所以宏观上也表现为一个立方体(理想情况).
第二题是由于蜡是一个分子晶体,分子里面相连的原子有很强的共价键,这导致每个蜡分子都十分稳定,但蜡的分子间却没有共价键,是靠比较弱的力(范德华力)联系的,所以蜡比较软,且熔点低.

中文都读不完了,还重洋迷外
