Synthesis Reactions Quiz

What is a synthesis reaction?

• A reaction where two or more reactants combine to form a single product

• A reaction where a single reactant breaks down into two or more products

• A reaction where two or more reactants exchange ions to form new compounds

• A reaction where a reactant combines with oxygen to produce carbon dioxide

Which of the following is a synthesis reaction?
