KEY TERMS: balance both sides of the equation by placing a number (coefficient) in front of the compound. Don't be afraid to have to change that number if it does not completely balance the equation. Balance polyatomic ions first. Remember that REACTANTS are to the left of the arrow and PRODUCTS are to the right of the arrow. Refer to episode on "Counting Atoms". Don't forget your diatomic molecules:
oxygen = O2
hydrogen = H2
bromine = Br2
chlorine = Cl2
iodine = I2
fluorine = F2
nitrogen = N2
