Writing Chemical Equations
1)Identify reactants, write chemical formulas.
2)Identify products, write chemical formulas.
3)Write the complete chemical equation.
4) Balance the equation.

Practice1) Aluminum bromide + calcium nitrate aluminum nitrate + calcium bromide.
2) Zinc bromide reacts with silver nitrate to produce zinc nitrate and silver bromide.
3) Lithium oxide combines with water to form lithium hydroxide.

Example 4: Merry and Pippin find lead (II) chloride and
lithium sulfate in Gandalf’s chemical supply cabinet. They combine these chemical compounds and then run to Gandalf so he may identify the produced chemical compounds. Gandalf identifies the compounds as lead (II) sulfate and lithium chloride.

Example 5 A chemist at a Wake Forest
chemistry lab prepares a potassium bromide solution dissolved in water to react with chlorine gas. This reaction produces bromine in the liquid state and potassium chloride in solution.
