✔ 最佳答案

點會出多原子離子（sulphide、sulphite、sulphate）呀？

sulphur + oxygen --> sulphur dioxide / S + O2 --> SO2
但呢個係吸熱反應，要將硫係氧氣下加熱先會進行

sulphur dioxide + oxygen <--> sulphur trioxide / 2SO2 + O2 --> 2SO3
但個反應更加唔會自然發生，要係高溫同催化劑（用鉑或V2O5）下先會進行，會用於製作硫酸的過程

I think not.
It is because S + O2 = SO2 , but when SO2 react with O2 ,
SO3 will be formed.

The eq. is S + O2 = SO2 ..... SO2 + O2 (reverse) SO3

Sulphur+ oxygen有幾個form嫁wo
1 = Sulphide
2 =sulphite
3=sulphate

because the charge of sulphur係1負，oxygen個charge都係2負

所以係
2- ← 2-係個Charge!
SO ←SO係sulphur+oxygen = sulphide

3-
SO = sulphite

4-
SO =sulphate

早知記住sulphur係負1 oxygen係負2,ate,ite,ide尾都係有oxygen同佢個element share 電子!

希望幫倒你唔明再同我講!

參考: chem 書都有^^
