Balancing Chemical Equations Video: Are Reactants and Products Mass Balanced? (Lecture 5)

Balancing chemical equations (balancing equations) is a very important skill that all chemistry students must master. Before working with any chemical equation it must be mass balanced in order to obey law of conservation matter (law of conservation of mass). The law of conservation of mass states that in an chemical reaction matter cannot be created nor destroyed. Therefore, the matter (mass) on the reactant side must equal the matter (mass) on the product side of the equation. This translates into the atoms on the left of the arrow must equal the atoms on the right of the arrow. For example, if on the left of the arrow there are 3 oxygen atoms then there has to be three oxygen on the right of the arrow.

A common question on chemistry exams is:
balance the following chemical equation followed by an unbalanced chemical equation.
