Word and Skeleton Equations
1. Examine the following word equation:
propane + oxygen  carbon dioxide + water
a) List all the reactants in this reaction. ___________________________________
b) List all the products in this reaction. ___________________________________
c) What is the purpose of the arrow in the word equation?
2. Write word equations for the following reactions:
a) CaCl2 and Na2SO4 react to form CaSO4 and NaCl
b) BaCO3 reacts when heated to produce BaO and CO2
c) AgNO3 reacts with KCl to produce AgCl and KNO3
For the following questions, write a) the word equation and b) the chemical equation (AKA the “skeleton equation”):
3. Magnesium metal burns in oxygen gas with a bright white light to make a white powder called magnesium oxide.
4. A solution of sodium iodide is added to a solution of potassium nitrate to make a potassium iodide precipitate and a
sodium nitrate solution.
5. Gaseous hydrogen and gaseous oxygen react explosively to form water vapor.
6. Aluminum resists corrosion because it reacts with a gas found in air to form a protective coating of aluminum oxide.
