Write one equation each for decomposition reactions where energy is supplied in the form of heat, light or electricity

Question: Write one equation each for decomposition reactions where energy is supplied in the form of heat, light or electricity

Answer: 

(a) Thermal Decomposition:

2FeSO₄(s) + Heat ⟶ Fe₂O₃(s) + SO₂(g) +  SO₃(g)

(b) Decomposition by Light: 

2AgCl(s) + Light ⟶ 2Ag(s) + Cl₂(g)

(c) Decomposition by Electricity:

2Al₂O₃(aq) + Electricity ⟶ 4Al(s) + 3O₂(g)
