When explaining chemical reactions to a friend, Brianna models a reaction by combining ingredients to make a cake. Which type of chemical reaction is Brianna most likely explaining?

Question

synthesis
decomposition
polymerization
replacement

Answer 1

Brianna is most likely explaining a synthesis reaction. In a synthesis reaction, two or more substances combine to form a single product, similar to how different ingredients are combined to create a cake. In contrast, decomposition reactions break down a compound into simpler products, polymerization involves the joining of small molecules to form a polymer, and replacement reactions involve the exchange of components between compounds.
