Question

In every balanced chemical equation, each side of the equation has the same number of _____.

Answer 1

The correct answer is option d, that is, atoms of the element.

The chemical reactions must be balanced, they must exhibit a similar number of atoms of each element on both the sides of the equation. As a consequence, the mass of the reactants must be equivalent to the mass of the products of the reaction.  

Answer 2

Atoms of element equation has the same number
