Answer: The chemical reaction for the synthesis reaction is given below.
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:
[tex]A+B\rightarrow AB[/tex]
For the reaction of calcium and oxygen combining together to form calcium oxide, the equation follows:
[tex]2Ca(s)+O_2(g)\rightarrow 2CaO(s)[/tex]
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.
