Question

H2O+CaO CaO+CO2 CaCO3=​

Answer 1

Ответ:

H₂O + CaO = Ca(OH)₂

CaO + CO₂ = CaCO₃

CaCO₃ = CaO +CO₂

Answer 2

The chemical reactions you've written involve the formation and decomposition of calcium carbonate (CaCO3). Here's the breakdown of each step:

1. H2O + CaO → Ca(OH)2 This reaction combines water (H2O) with calcium oxide (CaO) to form calcium hydroxide (Ca(OH)2).

2. Ca(OH)2 + CO2 → CaCO3 + H2O In this step, calcium hydroxide (Ca(OH)2) reacts with carbon dioxide (CO2) to produce calcium carbonate (CaCO3) and water (H2O).

So, overall, the reactions are:

H2O + CaO → Ca(OH)2 Ca(OH)2 + CO2 → CaCO3 + H2O

These reactions show the formation of calcium carbonate from calcium oxide, water, and carbon dioxide.
