Balancing an equation...Must be done on both ryt side and left side .You must see the number of moles of each elemnt in Lhs is equal to number of moles of each elemnt in Rhs

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.
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.
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.

Start with single elements. If you have more than one element left to balance, select the element that appears in only a single molecule of reactants and in only a single molecule of products. This means that you will need to balance the carbon atoms first.
