5月8日化学u1有选择题基本上是确定的,这个没有太多争议。关键是问答题可能会不太确定。下面就我对爱徳思的了解以及找了一些“证据”,也和一些同学进行了讨论,尝试“确定”一下答案,至少确定一下答案的方向。
确定答案如下:
Different sized atoms distort the layers of metal atoms, making it more difficult for them to slide over each other.
理由是课本找到原话:
确定答案如下:
--the layers in graphite are relatively far apart/graphite crystal contains a lot of wastedspace. --because there is relatively weak London forces of attraction between the layers.
理由是课本找到原话:
确定答案如下:
--There is nowater so the particles are not able to move to collide.
理由是固体的particles是固定的,不会发生collide;只是加了水溶液,particle才会move freely.
确定答案如下:
E-4-methylhex-2-ene而不是:“4-methylhex-2-ene”
理由是爱徳思大纲要求要写E/Z,并且往年真题也必须写:
