1.
a particle is confined to a one-dimension box of length 300 pm ,for∣∣∣
∣⊥∣
∣ 3
the particle is most likely to be found at
A.75pm B.100pm C.125pm D.175pm E.250pm
2.
in pure liquid ammonia ,the equilibrium concentration of both [NH4+] and
[NH2-] are 3x10^-14M at 25。C. Which of the following equation holds for
liquid ammonia solutions at 25。C ?
A.pNH4+ +pNH2-=13.5 B.pNH4+ = pNH2- =13.5 C.pNH4+ =27.0
D.pNH4+ = 27.0－ pNH2- E.pNH4+ =log[pNH4]
我选 BD
3.
which of the following is optically active?
A.2-chloropane B.3-chloropentane C.3,3-dichlorohexane
D.[CoCl6]3- E.[Co(en)3]3+
optically 是四边取代基都不同?!
4.
which of the following ligands might give linkage isomers?
1.NO2- 2.SCN- 3.H2N-H2C-CH2-NH2
(A)1 2 (B)1 3 (C)2 3 (D)none (E)1 2 3
这四题麻烦各位大大帮忙罗!!谢谢
ps:转胞加油:)

1F：→ pterome:4 linkage A 3是箝合 应该没有 07/04 10:47
2F：→ pterome:1 我也想知道答案 07/04 10:48
3F：→ com11080:可以解是一下吗?!不懂= = 07/04 10:48
4F：→ pterome:linkage指的是 Ｍ＋接ＮＯ2 接N OR ONO 接Ｏ 你问这? 07/04 11:11
5F：→ pterome:就= = 我怎麽表达 就 可不可以换接点? 同个配机 07/04 11:12
6F：→ pterome:三的话? 旧址有Ｎ钴对电子可以接点 好难描述我要说得 07/04 11:15
