Which parts must be balanced in a chemical equation?(1 point) Responses numbers of reactant and product atoms numbers of reactant and product atoms states of reactants and products states of reactants and products energy on the reactant and product sides energy on the reactant and product sides numbers of reactant and product molecules

Answer 1

In a chemical equation, the part that must be balanced is the numbers of reactant and product atoms. This ensures that the law of conservation of mass is upheld, meaning that the same number of each type of atom must be present on both sides of the equation.
