Balancing Equations Get an unbalanced equation. Draw boxes around all the chemical formulas. NEVER change anything inside of these boxes. EVER. Make an inventory of the elements on the reactants side and the products side. Write numbers in front of each of the boxes until the numbers for each element are the same on both sides.

Practice From Warm-Up: Al + HCl  AlCl3 + H2 N2 + H2  NH3

Balance these two equations: Debrief Balance these two equations: 1) H3PO4 + HCl  PCl5 + H2O 2) K + H2O  KOH + H2
