Answer: The substances present at the start of the reaction are "reactants" and the substances produced are "products"
Explanation:
When a reaction happens between different substances, it will produce a product or some products. The best way to visualize this process is using a chemical reaction, where the substances that are reacting will be on the left side and they will be called reactants and the substances produced will be on the right side of the equation and they will be called products. As we can check in the image.
A chemical reaction is a chemical change of the reactants to form a product. The substances present at the start are reactants and the produced are called products.
Reactants are chemical compounds or elements that react with each other to produce a new compound. These are the substances present at the start of a reaction.
The compounds that are formed as a result of the chemical reaction of reactants is called products.
Therefore, reactants are the compounds that are present at the start of the reaction, and products are formed at the end of the reaction.
