Charlie is balancing an equation. she has identified the atoms and counted the number of each in the reactants and products. what would charlie adjust to make the number of atoms in the reactants the same as the number of atoms in the products?

Stochiometric coefficients

Explanation: The chemical equations must be balanced to follow the law of conservation of mass which says that the mass of products must be same as the mass of reactants.

This is a skeletal equation  and needs to be balanced by adjusting the stochiometric coefficients. In order to keep the mass same, the number of atoms must be same on both sides.
