Question

Balance the following chemical reactions and state the type of chemical reactions:-
(1) H20 → H2 + O2 (ii) CaO + H2O + Ca(OH)2 (iii) CuO + H2 → Cu + H2O
(iv) Pb + CuCl2 → PbCl2 + Cu (v) FeSO4 → Fe2O3 +S02 + SO3​

Answer 1

Answer:

(1) 2H₂O→ 2H₂↑ + O₂↑

(ii) CaO + 2H₂O → Ca(OH)₂+Heat

(iii) CuO + H₂ → Cu + H₂O

(iv) Pb + CuCl₂ → PbCl₂ + Cu

(v) 2FeSO₄ → Fe₂O₃ +SO₂↑+ SO₃↑

Answer 2

2H2O = 2H + O2

CaO + H2O = Ca(OH)2

CuO + H2 = Cu + H2O

Pb + CuCl2 = PbCl2 + Cu

2FeSO4 = Fe2O3 + SO2 + SO3
