Which term means newly formed substances?

• A. Reactant
• B. Product
• C. Physical Change
• D. Metal

Answer: (B)

Newly formed substances are called products. In a chemical reaction, the starting materials are reactants, and they rearrange to form new substances—the products. This is why, in chemical equations, the reactants sit on the left and the products appear on the right after the arrow. A physical change doesn’t create new substances; it only changes state or appearance. A metal is an element and doesn’t describe the idea of something newly formed in a reaction.
