How to Balance H2 + Br2 = HBr

In order to balance H2 + Br2 = HBr 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 have you can only change the coefficients (the numbers in front of atoms or compounds) in order to balance the equation.

Be sure to add up all the H and Br atoms on both sides of 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.
