Make up the reaction equation: 1) Carbonate-carbon monoxide (II) 2) Mg (HCO3) 2- C

We carry out the first chain of reactions and obtain the following equations
Carbonate ->? -> carbon monoxide (II)
From carbonate, under the influence of temperature, we obtain CO2:
t °
CaCO3 —-> CaO + CO2
Then we add hydrogen and the following equation is obtained
CO2 + 2H2 —> CO + 2 H2O
then we carry out the second reaction
Mg (HCO3) 2 ->? -> C
From magnesium hydrocarbonate, we obtain tetravalent carbon monoxide under the influence of temperature
t °
Mg (HCO3) 2 —-> MgCO3 + H2O + CO2
Next, add metal to CO2 and get the following equation:
CO2 + 2 Na —> C + Na2O
