The correct answer is B. New substances that are present at the end of a reaction
Explanation:
The products of a reaction refer to the substances, elements, compounds that result from the original compounds or substances (reactants) changing or interacting during the reactions and that are new or different from the reactants. Due to this, the products obtained depend mainly on the reactants or original elements and the type of reaction that occurs as reactions can involve synthesis, decomposition, combustion, combination or displacement and each of these would lead to different types of products. According to this, the statement that describes the products of a reaction is "New substances that are present at the end of a reaction".
