Reaction Worksheet #1 Synthesis and Decomposition Name ___________________________ Favorite restaurant __________________ For each of the following reactions, write the overall balanced reaction with descriptive symbols ( (s), (l), (g), (aq), Δ). Then, write the balanced net ionic reaction. Then, answer the one question about each reaction. 1. Sulfur dioxide gas is bubbled through a solution of distilled water. overall: net ionic: What is the oxidation number of sulfur in the product? 2. Ammonium carbonate chunks are heated. overall: net ionic: Is this reaction exo- or endothermic? 3. Aluminum oxide powder is sprinkled into warm distilled water. overall: net ionic: Would the product solution be basic, neutral, or acidic? 4. Solid barium oxide is stirred into water. overall: net ionic: What is one solution that would make a precipitate when mixed with the product in this reaction? 5. Graphite (solid carbon) is burned in air. overall: net ionic: Which element was oxidized in this reaction? 6. Magnesium ribbon is burned in air. overall: net ionic: Which element is reduced in this reaction? 7. Hydrogen peroxide solution undergoes catalytic decomposition a using sodium iodide catalyst. overall: net ionic: How much sodium iodide would be present after the reaction? 8. Ethene and hydrogen gases are mixed and sparked. overall: net ionic: What is the hybridization at each carbon in the product? 9. Sodium oxide powder is warmed and has carbon dioxide gas blown across it. overall: net ionic: What is the molecular geometry of carbon dioxide? 10. Diphosphorus trioxide powder is stirred into distilled water. overall: net ionic: Is the phosphorus oxidized, reduced, or neither in this reaction? 11. Sodium metal is dropped into a chlorine gas atmosphere. overall: net ionic: Which element is the oxidation agent in this reaction? 12. Solid boron trifluoride is introduced into an ammonia atmosphere. overall: net ionic: What is the molecular geometry of the boron trifluoride?
