The word equation for a chemical reaction is shown below. Zinc plus hydrochloric acid reacts to form zinc chloride plus hydrogen. What are the reactants in this reaction?

In order to solve this question, let us first review the arrangement of a word equation. The reactants in a word equation are the chemicals our reaction starts with and are located on the left-hand side of a word equation. An arrow is used to separate the reactants from the chemicals that are formed during the reaction, which are called the products.

Now let us take a look at the word equation given in this problem and correctly identify the location of the reactants, which would be given on the left-hand side. We now know that zinc and hydrochloric acid are the reactants, whereas the chemicals to the right of the arrow are the products, which are zinc chloride and hydrogen. Therefore, the reactants in this reaction are zinc and hydrochloric acid. The correct answer is zinc and hydrochloric acid.
