Na2CO3 → CO2 → C→ CO → CO2→ H2CO3
1) Na2CO3 + 2HCl → 2NaCl + H2O + CO2↑;
2) CO2 → C + O2↑;
3) 2C + O2 → 2CO;
4) 2CO + O2 → 2CO2↑;
5) H2O + CO2 → H2CO3.
H2SO4 → SO2 → SO3 → Na2SO4 → BaSO4
1) 2H2SO4 + Cu → CuSO4 + SO2↑ + 2H2O;
2) 2SO2 + O2 → 2SO3;
3) Na2O + SO3 → Na2SO4;
4) Na2SO4 + BaCl2 → 2NaCl + BaSO4↓.
