Answer 1

6.1 2Ca + O2 → 2CaO
6.2 CaO + CO2 → CaCO3
6.3 CaO + 2H2O → Ca(OH)2
6.4 Ca(OH)2 + H2SO3 → CaSO3 + 2H2O
6.5 CaSO3 + 2HCl → CaCl2 + H2O + SO2
6.6 CaSO3 + 2HCl → CaCl2 + H2O + SO2
6.7 2NaOH + SO2 → Na2SO3 + H2O
6.8 Na2SO3 + H2SO4 → Na2SO4 + H2SO3
6.9 2NaOH + H2SO3 = Na2SO3 + 2H2O
6.10 ---
6.11 CuO + H2 → Cu + H2O
