Question

Give two example of thermal and photo chemical decomposition​

Answer 1

Explanation:

Thermal Decomposition:

1. feSO4-)fe2O3+ SO2+ SO3

2.CaCO3-) CaO+ CO2

Photo Chemical Decomposition:

1.AgCl(silver chloride)-)Ag+ Cl2

2. AgBr-) Ag+ Br2

Answer 2

photo decomposition

2AgCl=Ag +Cl2

2AgBr= Ag. + Br2

thermal

CaCO3= CaO +CO2

2FeSO4= Fe2O3 + SO2 + SO3
