Detailed Solution

According to the Law of Conservation of Mass, matter can change forms, mixtures can be created or separated, and pure substances can be broken down, but the overall amount of mass does not change.
Every time matter undergoes a transformation, the total mass of the products is, within detectable limits, the same as the total mass of the reactants.
This means that the overall mass of the universe is constant within measurable bounds.
Equations are balanced in order to comply with the law of conservation of mass, which states that the mass of products in a reaction must equal the mass of reactants.
