Balance C2H5OH+O2 = CO2 + H2O (Ethanol and Water)

In this video we'll balance the equation C2H5OH+O2 = CO2 + H2O and provide the correct coefficients for each compound.

In order to balance C2H5OH+O2 = CO2 + H2O you'll need to watch out for two things.

First, be sure to count all of C, H, and O atoms on each side of the chemical equation. Once you know how many of each type of atom you have you can only change the coefficients (the numbers in front of atoms or compounds) in order to balance the equation.

Be careful when counting the Oxygen atoms on the product side of the equation. Don't forget the O in H2O! Often for combustion reactions it is easiest to leave the O2 until last.

Important tips for balancing chemical equations:

- Only change the numbers in front of compounds (the coefficients).
- Never change the numbers after atoms (the subscripts).
- The number of each atom on both sides of the equation must be the same for the equation to be balanced.
