✔ 最佳答案
Mg(s) +2H+(aq) ->Mg2+(aq) + H2(g)2H+(aq) + CO32- -> H2O(l) + CO2(aq) or (g)
HCO3-(aq) + H+ (aq) -> H2O(l) + CO2(aq) or (g)
Fe2O3 (s) +6H+(aq) -> 2Fe3+(aq) +3H2O(l)
OH-(aq) + H+(aq) ->H2O (l)

thank you 土扁 , you are right
I accidentally changed the Fe(OH)3 into Fe2O3
and the CO2 emitted in (b) and (c) should be in gaseous state

(b), (c)
The state symbol for the carbon dioxide formed should be (g). This is because only a very small portion of carbon dioxide is dissolved in the aqueous solution.
(d)
The chemical formula of Iron(III) hydroxide should be Fe(OH)3.
