Chemical Reaction Formula
A chemical reaction involves the rearranging of atoms of the same or different elements to form new substances. It is represented by a chemical equation in which the reactants (substances that are broken apart) are written on the left and the products (new substances formed) are written on the right. If more than one reactant or product is needed, they are separated with a + sign. An arrow is used to separate the reactant side of the equation from the product side.

Chemical Reaction Formula Examples:
1. Methane (CH4) and oxygen (O2) react to produce carbon dioxide (CO2) and water (H2O).
CH4 and O2 are the reactants, while CO2 and H2O are the products.
2. Sodium metal (Na) reacts with water (H2O) to form sodium hydroxide (NaOH) and hydrogen gas (H2).
Na and H2O are the reactants, while NaOH and H2O are the products.
