Write the reaction equation: C → Al4C3 → CH4 → CO2 → CaCO3 → Ca (HCO3) 2 → CaCO3 → CO2 → CO → HCOONa → Na2SO4

1) 4Al + 3C → Al4C3;

2) Al4C3 + 12H2O → 4Al(OH)3↓ + 3CH4↑;

3) CH4 + 2O2 → CO2 + 2H2O;

4) Ca(OH)2 + CO2 → CaCO3↓ + H2O;

5) CaCO3 + CO2 + H2O → Ca(HCO3)2;

6) Ca(HCO3)2 → CaCO3↓ + CO2 + H2O;

7) CaCO3 → CaO + CO2↑;

8) CO2 + C → CO;

9) CO + NaOH → HCOONa;

10) 2HCOONa + H2SO4 → 2HCOOH + Na2SO4
