Объяснение:
Na2CO3 + 2HCl = 2NaCl + CO2 + H2O ( карбонат натрия, соляная кислота, хлорид натрия, оксид углерода(4), вода)
2Na(+) + CO3(2-) + 2H(+) + 2Cl(-) = 2Na(+) + 2Cl(-) + CO2 + H2O
CO3(2-) + 2H(+) = CO2 + H2O
CO2 + C = 2CO (оксид углерода(4), углерод, оксид углерода(2)
C(+4) +2e = C(+2) 1 в-ие
ок-ль
C(0) -2e = C(+2) 1 ок-ие

2CO + O2 = 2CO2 (оксид углерода(2), кислород, оксид углерода(4)
C(+2) -2e = C(+4) 2 ок-ие
в-ль
O2(0) +4e = 2O(-2) 1 в-ие

CO2 + 2KOH = K2CO3 + H2O (оксид углерода(4), гидроксид калия, карбонат калия, вода)
CO2 + 2K(+) + 2OH(-) = 2K(+) + CO3(2-) + H2O
CO2 + 2OH(-) = CO3(2-) + H2O
K2CO3 + CO2 + H2O = 2KHCO3 ( карбонат калия, оксид углерода(4), вода, гидрокарбонат калия)
2K(+) + CO3(2-) + CO2 + H2O = 2K(+) + 2HCO3(-)
CO3(2-) + CO2 + H2O = 2HCO3(-)
