Question

which condition must be met in order for an equation to be balanced? the elements in the reactants are the same as the elements in the products. there are fewer elements in the reactants than there are in the products. the number of atoms in the reactants is greater than the number of atoms in the products. the number of atoms in the reactants equals the number of atoms in the products.

Explanation:

In a balanced chemical equation, the law of conservation of mass must be obeyed. This means the number of atoms of each element in the reactants must equal the number of atoms of the same element in the products.

Answer:

D. The number of atoms in the reactants equals the number of atoms in the products
