Question

the inputs of a chemical reaction. located on the left side of a chemical equation. choose an answer lets try again 1 cofactors 2 products 3 intermediates 4 reactants

Explanation:

In a chemical equation, reactants are the substances that undergo a chemical change. They are located on the left - hand side of the equation. The term "reactants" directly matches the description of the "inputs" of a chemical reaction located on the left side of a chemical equation. Cofactors are non - protein chemical compounds that assist in biochemical reactions (not relevant here). Products are on the right - hand side of the equation. Intermediates are short - lived species formed during a reaction mechanism (not the initial inputs).

Answer:

1. reactants
