  • Step 3 Balance the equation with your model  HH+OO-----> HHO we have 2 h's on both sides and we need to balance the oxygen  molecule in order to balance the product side we can only add in H20 to balance the equation. the only way  we can add more oygen is to add another molecule of H2O (water)  HH+OO -----> OHH we have a problem and need to balance.  HH+OO -------> OHH OHH  we still have an unbalanced equation. So we need to add more hydrogen to the reactant side  H2+O2----->2 H2O we now need to add more hydrogen to balance and our end product looks like this: 2H2 + O2  =   2H2O 
  • Step 4 Continue adding coefficents to get the same number of atoms on both sides for each element 2H+02------> 2H2O
  • always start with metals followed by non metals and balance oxygen last
  • step 5 check your work make sure both sides are balanced equally.
