These are contrary reactions.

Which the following is a necessary product of a combustion reaction

heat

What happens in a double replacement reaction

In this reaction a change of bonds of the reactants occur: the general form is:
AB + CD = AD + BC

What is a following is a decomposition reaction

CaCO3 -> CaO + CO2
