We write down the reactions of formation of the given compounds.
CaSO4 + MgCO3 = CaCO3 + MgSO4.
The reaction is called an exchange reaction to form calcium carbonate and magnesium sulfate.
CaCO3 + H2SO4 = CaSO4 + H2CO3.
The reaction is called an exchange reaction with the formation of calcium sulfate and carbonic acid.
CaSO4 + С = СaS + 2CO + CO2.
The reaction is called a substitution reaction to form calcium sulfide, carbon monoxide and tetravalent carbon monoxide.
CaS = Ca + S.
Decomposition to produce calcium and sulfur.
