A product that is a chemically bonded combination of reactants will form in which type of reaction? Check all that apply.

synthesis

A) polymerization

B) decomposition

C) oxidation

D) replacement

Both synthesis and polymerization processes create chemically bonded combination of reactants. Synthesis is a reaction which uses various reactants to form one product, for example formation of water from hydrogen and oxygen. Polymerization illustrates the same process, wherein it uses simple monomer molecules in a reaction to create longer polymer chains, for example formation of proteins through polymerization of amino acids.
