B. Decomposition reaction
C. Combustion reaction
D. Synthesis reaction

Answer 1

A synthesis reaction combines simpler reactants to form a new compound.

Step-by-step explanation:

A reaction that combines simpler reactants to form a new compound is called a Synthesis reaction. In a synthesis reaction, two or more substances combine to form a single new substance. The general form of a synthesis reaction is: A + B → AB. For example, the reaction of sodium metal (Na) with chlorine gas (Cl2) to form sodium chloride (NaCl) is a synthesis reaction.
