4 Worksheet #1: Writing and Balancing Formula Equations Step 1: Write each formula and balance each formula using SUBSCRIPTS. Step 2: Balance the overall equation using coefficients. 1. sulfur + oxygen sulfur dioxide 2. zinc + sulfuric acid zinc sulfate + hydrogen 3. hydrogen + nitrogen ammonia 4. hydrogen + chlorine hydrogen chloride 5. carbon + water carbon monoxide + hydrogen 6. calcium oxide + water calcium hydroxide 7. phosphorus + oxygen diphosphorus pentoxide 8. hydrochloric acid + sodium hydroxide sodium chloride + water 9. barium chloride + sulfuric acid barium sulfate + hydrochloric acid 10. aluminum sulfate + calcium hydroxide aluminum hydroxide + calcium sulfate 11. ethane (C 2 H 6 ) + oxygen carbon dioxide + water 12. aluminum oxide aluminum + oxygen

5 Worksheet #2: Synthesis Reactions In synthesis reactions, two or more reactants come together to form one compound. A + B AB Complete the following word equations, and write and balance the formula equation. 1. calcium + oxygen 2. copper + sulfur copper(ii) sulfide 3. calcium oxide + water calcium hydroxide 4. hydrogen + nitrogen 5. hydrogen + chlorine 6. silver + sulfur 7. chromium + oxygen 8. aluminum + bromine 9. sodium + iodine 10. hydrogen + oxygen 11. aluminum + oxygen

6 Worksheet #3: Decomposition Reactions In decomposition reactions, one compound will break down into two or more parts. 1. barium carbonate 2. magnesium carbonate 3. potassium carbonate 4. zinc hydroxide 5. Iron(II) hydroxide 6. nickel(ii) chlorate 7. sodium chlorate 8. potassium chlorate 9. sulfuric acid 10. carbonic acid 11. aluminum oxide 12. silver oxide

7 Worksheet #4: Single-Replacement Reactions Step 1 - Write the formulas of the reactants on the left of the yield sign Step 2 - Look at the Activity Series to determine if the replacement can happen Step 3 - If the replacement can occur, complete the reaction and balance it. If the reaction cannot happen, write N.R. (no rxn) on the product side. 1. lead + zinc acetate 2. iron + aluminum oxide 3. silver nitrate + nickel 4. sodium bromide + iodine 5. aluminum bromide + chlorine 6. sodium iodide + bromine 7. calcium + hydrochloric acid 8. magnesium + nitric acid 9. silver + sulfuric acid 10. potassium + water 11. sodium + water

8 Worksheet #5: Double-Replacement Reactions In these reactions, all you do is look at the names of the reactants, and "switch partners". Just be sure that the new pairs come out with the positive ion named first, and paired with a negative ion. 1. aluminum iodide + mercury(ii) chloride 2. silver nitrate + potassium phosphate 3. copper(ii) bromide + aluminum chloride 4. calcium acetate + sodium carbonate 5. ammonium chloride + mercury(i) acetate 6. calcium nitrate + hydrochloric acid 7. iron(ii) sulfide + hydrochloric acid 8. copper(ii) hydroxide + acetic acid 9. calcium hydroxide + phosphoric acid 10. calcium bromide + potassium hydroxide Examine the products of the reactions on this page, and determine in each whether a gas, water, or a precipitate is formed. Use solubility rules from your notes or at the back of your textbook to determine the solubilities of the reaction products. If there is no gas, water, or precipitate produced, put an "X" through the yield sign, because no reaction occurs.

9 Worksheet #6: Combustion Reactions We will focus on the combustion of hydrocarbons. Hydrocarbons react with oxygen to form carbon dioxide and water. 1. methane (CH 4 ) + oxygen 2. ethane (C 2 H 6 ) + oxygen 3. propane (C 3 H 8 ) + oxygen 4. butane (C 4 H 10 ) + oxygen 5. pentane (C 5 H 12 ) + oxygen 6. hexane (C 6 H 14 ) + oxygen 7. ethene (C 2 H 4 ) + oxygen 8. ethyne (C 2 H 2 ) + oxygen 9. benzene (C 6 H 6 ) + oxygen
