Question

2. Balance the following equations :
(1) Fe(s) + H2O (g) → Fe3O4(s) + H2(g)
heat
(ii) FeSO4(s) ► Fe2O3(s) + SO2(g) + SO3(g)
(iii) MnO2(s) + HCl
MnCl(aq) + Cl2(g) + H2O(1)​

Answer 1

Explanation:

(1) 3Fe+ 4H2O= Fe3O4 + 4H2

(2) 2FeSO4= Fe2O3+SO2+ SO3.

(3) 2MnO2 + 4HCl= 2MnCl+ Cl2 + 2H2O
