Let us indicate the names of the substances: Ca – metal, belongs to the active ones, since in the table the Row of stress of metals is up to aluminum. The main oxide is calcium oxide, calcium hydroxide is the base. Genetic schema solution:
Ca + O2 = CaO – oxidation;
CaO + H2O = Ca (OH) 2 – reaction with heat release – exothermic.
Reaction products are of practical importance in construction: quicklime and hydrated lime.
