50 examples of balanced chemical equations with answers
The balanced chemical equation was used to calculate the mass of product that is formed from a certain amount of reactant. It can also be used to determine the masses of reactants that are necessary to form a certain amount of product or, as shown in Example \(\PageIndex{1}\), the mass of one reactant that is required to consume a given mass of ...For example, consider the reaction: 2M g(s)+O2(g) 2M gO(g) ,In this reaction, 2 atoms of magnesium and oxygen is present on both sides of the reactant and product side. hence the chemical reaction obeys the law of conservation of mass so the chemical reaction is a Balanced chemical equation.
