Which of the following statements correctly identifies the synthesis reaction and describes a substance involved?
Chemical reaction A, because the reactant is a compound
Chemical reaction B, because the product is a compound
Chemical reaction A, because the reactant is an element
Chemical reaction B, because the product is an element

Chemical reaction B, because the product is a compound

Explanation:

A synthesis or combination reaction is that reaction that involves combination of two or more reactants to form a single product. The two or more reactants are often elements that chemically combine to form a single compound.

In this question, two chemical reactions are involved in which chemical reaction A has 1 reactants and 3 products while chemical reaction B has 2 reactants and 1 product. Based on the explanation above, the reaction B correctly identifies the synthesis reaction because the single product is a compound.
