Question

give balanced equations for each of the decomposition reaction carried out with the help of 1) electricity 2)heat 3)sunlight

Answer 1

1) H2o------------- H2+O2
balanced = 2 H2o------- 2 H2 + O2

2) FeSO4-------- Fe2O3+ SO2 + SO3
balanced= 2 FeSO4--------Fe2O3+ SO2 + SO3

3)AgCl--------Ag+ Cl2
balanced = 2AgCl --------- 2Ag+ Cl2
