Make up the equation of chemical reactions according to the transformation scheme: С – СО – СО2 – H2CO3 – Na2CO3 – CaCO3
| December 11, 2020 | education
The transformation chain looks like this:
1) 2C + O2 = 2CO
2) 2CO + O2 = 2CO2
3) CO2 + H2O = H2CO3 (reversible reaction)
4) H2CO3 + 2NaOH = Na2CO3 + 2H2O
5) Na2CO3 + CaCl2 = CaCO3 + 2NaCl
