<human>:  How to balance chemical equations?
<bot>: 
1. Start by writing down the equation you wish to balance.
2. Make sure to write down the total number of atoms for each element on the left and right side.
3. Identify any coefficients that need to be placed in front of the formulas to indicate the correct number of elements.
4. Begin balancing the equation by adjusting the coefficients, making sure that the same number of each element appears on both sides of the equation.
5. When the coefficients cannot be adjusted any further, ensure that the number of atoms that appear on the left side is equal to the number of atoms that appear on the right side.
6. Finally, double-check the equation to make sure it is balanced.
