Question

CO2+NaOH = H2SO4+CaO=

Answer 1

CO2 + 2NaOH -> Na2CO3 + H2O

H2SO4 + CaO -> CaSO4 + H2O

Answer 2

The chemical equation you provided is actually two separate equations. Here they are, balanced and separated:

1. CO2 + NaOH → NaHCO3 Carbon dioxide (CO2) reacts with sodium hydroxide (NaOH) to produce sodium bicarbonate (NaHCO3).

2. H2SO4 + CaO → CaSO4 + H2O Sulfuric acid (H2SO4) reacts with calcium oxide (CaO) to produce calcium sulfate (CaSO4) and water (H2O).

Please note that these reactions are only valid under certain conditions (e.g. temperature, pressure, concentrations), and should only be performed with appropriate safety measures.
