You should put a 3. That way there are 6 H and 3 O on each side.
B. The chemical reaction that represents oxidation - reduction reaction is CaCO3(s) → CaO(s) + CO2(g).
<h3>
Oxidation reduction reaction</h3>
In oxidation reduction reaction, the oxidizing agent is reduced while reducing agent is oxidized.
<h3>In the chemical equation below;</h3>
CaCO3(s) → CaO(s) + CO2(g)
Calcium (ca) is oxidized calcium (II) ion while the carbon (IV) oxide is reduced carbon (IV) oxide.
Thus, the chemical reaction that represents oxidation - reduction reaction is CaCO3(s) → CaO(s) + CO2(g).
