Question

what component of a chemical reaction is highlighted in red? 2h₂(g) + cl₂(g) → 2hcl(g)

Explanation:

In a chemical - reaction equation, the substances on the left - hand side are reactants and those on the right - hand side are products. Coefficients are the numbers in front of the chemical formulas that balance the equation. Subscripts are the numbers within the chemical formulas indicating the number of atoms of each element in a molecule. Here, the highlighted numbers (2) are coefficients that balance the number of atoms on both sides of the reaction.

Answer:

coefficients
