Question

What is the term used for the elements and compounds before a chemical reaction takes place?

Answer 1

Explanation:

Before a chemical reaction, the elements and compounds which are about to take part in the reaction are known as reactants.

And, when the chemical reaction takes place between the given elements and compounds then they change into products.

For example, we take sodium and chlorine elements and before any chemical reaction they are the reactants.

But when a chemical reaction takes place between sodium and chlorine then it results into the formation of sodium chloride which is the product.
