  5. Practice Counting Atoms • How many calcium atoms? • How many nitrogen atoms?

  6. Practice Counting Atoms • How many carbon atoms? • How many oxygen atoms? • How many lead atoms?

  7. Box Method - Steps • Look at the first item in the equation • Write down the symbols of each element present the number of times it appears in the formula • Put a box around it • Repeat for each item in the equation • Check if mass is conserved • Add boxes until there are the same number of each atom on each side

  8. Line Method - Steps • 1. List out the atoms • 2. Count the number of each type of atom in the reactant • 3. Count the number of each type of atom in the product • 4. Note which atoms are not balanced • 5. Select one atom to balance • 6. Update the atom counts • 7. Repeat steps 4-6 until all are balanced
