Part II: Balancing Equations and Reaction Types
Directions: Write a balanced equation for each situation. If applicable, predict the products. List the reaction type on the answer sheet as oxidation-reduction, combination, decomposition, neutralization, precipitation, gaseous or combustion, ONLY. (All other answers for this section will be omitted.) If no reaction occurs, then list NO RXN as the product. However, still indicated the reaction type.1. Potassium chlorate decomposes to potassium chloride and oxygen.
2. A strip of copper is placed into a test tube containing silver nitrate solution.
3. Hydrochloric acid is added to a sodium carbonate solution.
4. A solution of potassium hydroxide is placed in a test tube containing nitric acid.
5. A strip of lead is placed into a beaker containing a silver nitrate solution.
6. A solution of zinc chloride is reacted with ammonium sulfide.
7. A piece of sodium is dropped into a beaker of water.
8. A solution of sodium carbonate is placed in a test tube containing hydrochloric acid.
9. A test tube full of sodium hydroxide is poured in a beaker containing ammonium nitrate.
10. Barium chloride solution is poured into a test tube containing sulfuric acid.
11. Fluorine is heated in water to produce hydrofluoric acid and oxygen.
12. Lead(II) nitrate is heated to produce lead(II) oxide, nitrogen monoxide and oxygen.
3. Aluminum and oxygen is heated to form aluminum oxide.
14. A magnesium strip is placed into a beaker of hydrochloric acid.
15. Cobalt(II) chloride, hexahydrate decomposes in the presence of heat to produce colbalt(II) chloride and water.
