Wired Faculty App

Balance the following chemical equations:
(i)    NaOH + H2SO4 → Na2SO4 + H2O
(ii)    HNO3 + Ca(OH)2 → Ca(N03)2 + H2 O
(iii)    FeCl2 + H2S → HCl + FeS 

Solution

These equation can be balance in steps.

(i)    
a)2NaOH + H2SO4 → Na2SO4 + H2O
b)2NaOH + H2SO4 → Na2SO4 + 2H2O

(ii)    
a)2HN03 + Ca(OH)2 → Ca(NO3)2 + H2O
b)2HNO3 + Ca(OH)2 → Ca(NO3)2 + 2H2O

(iii)    FeCl2 + H2S → 2HCl + FeS.
