13. Write the balanced chemical equation to support each of the statements given below (use only dilute sulphuric acid). a. Basic oxide + acid → salt + water b. Metallic carbonate + acid → salt + water + carbon dioxide
(i) Dilute H2SO4 reacts with basic oxides to form sulphate and water.
CuO+H2SO4 → CuSO4+H2O
(ii) It reacts with carbonate to produce CO2.
Na2CO3+H2SO4 → Na2SO4+H2O+CO2 ↑
