Let us write down the reaction equations for the next chain of compounds.
Ca -> CaO -> Ca (OH) 2 -> CaCO3 -> CaSO4.
1. The reaction is called a compound reaction or combustion reaction, with the formation of calcium hydroxide.
2Са + О2 = 2СаО.
2. The reaction of the compound, with the formation of calcium hydroxide.
CaO + H2O = Ca (OH) 2.
3. Exchange reaction or neutralization reaction, with the formation of calcium carbonate and water.
Ca (OH) 2 + CO2 = CaCO3 + H2O.
4. The reaction is called an exchange reaction with the formation of calcium sulfate, carbon monoxide and water.
CaCO3 + H2SO4 = CaSO4 + H2O + CO2.
