Question

what is the correct way to balance a chemical equation? * balance the equation by changing the coefficients so that the number of atoms of each element is equal on both sides. balance the equation by changing the subscripts in the chemical formulas. balance the equation by adding more products to the right side. balance the equation by removing reactants until the numbers match.

Explanation:

The principle of balancing a chemical equation is to adjust the coefficients (the numbers in front of chemical formulas) to make the number of atoms of each element equal on both the reactant and product sides. Changing subscripts would change the identity of the substances, adding products or removing reactants is not a proper way to balance.

Answer:

A. Balance the equation by changing the coefficients so that the number of atoms of each element is equal on both sides.
