Answers
Answer:
A chemical equation is a written symbolic representation of a chemical reaction (The symbols are the elemental letter or letters representing that element). The reactant chemical(s) are given on the left-hand side and the product chemical(s) on the right-hand side. The two are connected with an arrow leading from the left to the right, symbolizing the reaction. The law of conservation of mass states that no atoms can be created or destroyed in a chemical reaction, so the number of atoms that are present in the reactants has to balance the number of atoms that are present in the products.

Explanation:
Write down your given equation. For this example, you will use:
C3H8 + O2 --> H2O + CO2
This reaction occurs when propane (C3H8) is burned in the presence of oxygen to produce water and carbon dioxide.
Write down the number of atoms per element. Do this for each side of the equation. Look at the subscripts next to each atom to find the number of atoms in the equation. When writing it out, it's a good idea to connect it back to the original equation, noting how each element appears.[2]
For example, you have 3 oxygen atoms on the right side, but that total results from addition.
Left side: 3 carbon (C3), 8 hydrogen (H8) and 2 oxygen (O2).
Right side: 1 carbon (C), 2 hydrogen (H2) and 3 oxygen (O + O2).
Save hydrogen and oxygen for last, as they are often on both sides. Hydrogen and oxygen are both common in molecules, so it's likely that you'll have them on both sides of your equation. It's best to balance them last.[3]
You'll need to recount your atoms before balancing the hydrogen and oxygen, as you'll likely need to use coefficients to balance the other atoms in the equation.
