Answer 2

Answer : The correct option is, reactants

Explanation :

Chemical equation : In a chemical reaction, when the reactants are combined or separated to form new products.

For example :

$6Li+N_2\rightarrow 2Li_3N$

This is a chemical reaction in which the 'Li' and $N_2$ are the reactants and $LiN_3$ is the product.

In $6Li$ and $2Li_3N$, 6 and 2 are the coefficients.

Therefore, the substances in a chemical reaction that are combined or separated to form new substances are the reactants.
