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)
