Answer: The chemical reaction for the synthesis reaction is given below.

Step-by-step explanation:

Synthesis reaction is defined as a chemical reaction in which two small chemical substances combine together to form a single compound. The general equation for this chemical reaction follows:


A+B\rightarrow AB

For the reaction of calcium and oxygen combining together to form calcium oxide, the equation follows:


2Ca(s)+O_2(g)\rightarrow 2CaO(s)

By Stoichiometry,

2 moles of calcium element combines together with 1 mole of oxygen gas to produce 2 moles of calcium oxide.

Hence, the chemical equation for the reaction is given above.
