| 1. Make the equation for the reaction of calcium combustion. As a result, calcium oxide is formed.
2 Ca + O2 = 2CaO.
2. Calcium oxide – basic oxide, reacting with water, forms a base – calcium hydroxide.
CaO + H2O = Ca (OH) 2.
3. The reaction between calcium hydroxide and hydrochloric acid proceeds with the formation of calcium chloride and water.
Ca (OH) 2 + 2HCl = CaCl2 + 2H2O.
4.To obtain calcium carbonate from calcium chloride, let’s compose the reaction equation with carbonic acid.
CaCl2 + H2CO3 = CaCO3 + 2HCl.
5. Calcium oxide from calcium carbonate is obtained by the decomposition reaction of calcium carbonate.
CaCO3 = CaO + CO2.
