Steps to balance equations: 1) Start with the most complex compound/formula unit in the equation 2) Move element by element through that compound and make the number equal on both sides of the equation. 3) The law of conservation of mass says that you have to have the same number of atoms of each element on both sides of the equation.

1 Start here 1 N on product and 2 on reactant. Place 2 as coeeficient 2 The N is balanced. 2 on both sides. 3 There are 6 H atoms on the product side. Add a 3 to even it out.

1 Start here because it is the most complex. Begin with Al. There are 2 on the product side and 1 on the reactant side. 2 Adding a 2 balanced the Al but not the Br. There are now 6 Br on the reactant side and 1 on the product. 3 Even up the Br by placing a 6 as the coefficient. Now there are 6 K on the product and 2 on the reactant. 4 Even up the K by placing a 3 as the coefficient. Now there are 6 K on the product and 6 on the reactant. Now check the S and O. It just so happens that placing the 3 as the coefficient balanced them up as well. 3S and 12O on both sides.
