例如點知個product會咁
S2O3 2- + H+ => SO2 + S + H2O
點解佢會form sulphur????冇S都可以balance到
點解metal + cold water=> metal hydroxide
while metal + steam => metal oxide
all of these are metal + water, but they hv diff product
i want to ask if we add potassium + steam, will it be potassium hydroxide again?
另外又例如以下,點解
MgSO4+NaCl唔會有反應
MgCl2+Na2SO4就會有反應
咁應該用咩theory去predict
大家可以用深奧d的explanation
我要讀完大學,但始終都未清到呢d concept
更新1:
唔該晒你 但可否詳細解釋 點解會只可這樣行??MgCl2+Na2SO4- MgSO4+NaCl 呢條又係咁Pb(NO3)2 + Na2SO4 - PbSO4 + NaNO3 then 應該點解釋呢,係咪話關cation anion 的大小事 可否詳盡 and 深奧些冇問題 但想明瞭 希望能答我,thanks
