It states that the mass of the reactants must be equal to that of the products. To do this, the number of atoms in the reactants must be equal to that of the products. Therefore, we need to balance the equation, because it is not always ready for the entrance exam. 1:11 to 2:08 - A very simple example of how to balance an equation. 2:09 to 3:36 - A trick to learn the order you should follow when balancing chemical equations. You should do this process in the following order: metal, non-metal, carbon, hydrogen and oxygen. 3:37 to 11:21 - Examples of balancing equations.
