3),4)點解vapourcomposition係曲因為Dalton's law of partial pressure?個答案係咪即係上面條線concave upwards, 下面就直線?
其實係咪所有ideal solution 的vapour pressure-liquid 同vapour同liquid composition 都係咁?而boiling point- vapour同liquid composition curve就一條concave upwards, 一條concave downwards?

7)即係inorganic唔駛?

8)我睇2本書都係咁寫:
Ester formation: warm the carboxylic acid with an absolute alcohol in the presence of conc. H2SO4(l), followed by adding Na2CO3(aq)

boiling point- vapour同liquid composition curve就一條concave upwards, 一條concave downwards

呢個係因為b.p做experiment永遠都係有少少曲(其實v.p係畫曲左都唔會扣分)

7)大部分，但你做reduction potentail o個d寫返好d
仲有如果個reaction係有目的地出ppt/gas，寫左會好
e.g S2O32- + 2H+ -> S(s) + SO2(g)

8)有兩個TEST
1)我用左咁耐都係只加HCO3-==>GAS EVOLVED
2)warm the carboxylic acid with an absolute alcohol in the presence of conc. H2SO4(l), followed by adding Na2CO3(aq)
第2TEST入面個 CARBONATE可以EVAPORATE D ESTER，令人快D閒到佢D味
