In this video we'll balance the equation Al2(CO3)3 = Al2O3 + CO2 and provide the correct coefficients for each compound.

To balance Al2(CO3)3 = Al2O3 + CO2 you'll need to be sure to count all of atoms on each side of the chemical equation.

Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Decomposition of Aluminum carbonate.

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.
