calculate the masses of reactants to ensure chemical equations to substances shown in a that all of the other calculate the masses of balanced symbol reactant is used. The substances present. equation reactant that is calculate the masses of completely used up is called the limiting reactants and products reactant because it from the balanced symbol limits the amount of equation and the mass of products. a given reactant or product. The masses of reactants and products can be calculated from balanced symbol equations. Chemical equations can be interpreted in terms of moles. For example: Mg + 2HCl MgCl2 + H2 shows that one mole of magnesium reacts with two moles of hydrochloric acid to produce one mole of magnesium chloride
