In this activity, you will be performing two tasks:
  1. Identifying the type of reaction (combination, decomposition, combustion, single-replacement, or double-replacement).
  2. Balancing the reactions.
  • Abbreviated reaction types have been provided to help you identify the reaction types.
  • To balance the equations, you first must determine if each of these reactions is balanced; if not, then you must balance them.
  • Use your notes to help you balance the equations.
  • When balancing the equations, there are times only you will not need to increase the atoms in a given molecule; for these cases, place a hyphen (-) in the blank (this is only to make formative 'happy' as it will not permit an unused blank).
