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) to balance the equation.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.
