Name: _____________________________ Quiz Section:_______ CHEM 120A – Autumn 2011 Worksheet #6 1. Nitrogen dioxide reacts with water to produce oxygen and ammonia a. Write a balanced chemical equation for the reaction (all reactants and products are gaseous) b. How many liters of oxygen at STP are produced when 2.5 x 10 23 molecules of nitrogen dioxide react? 2. What is the pressure, in atm, of 8.0 g of oxygen gas that has a volume of 245 mL at a temperature of 22°C? 3. When heated, solid KClO 3 forms solid KCl and oxygen gas. a. Write a balanced chemical equation for this reaction (include the correct states for each reactant and product). b. What is the volume, in mL, of oxygen gas that is produced at 26°C and 719 mmHg from the reaction of 0.712 g of KClO 3 ?

Unformatted text preview: 6. When solutions of silver nitrate and sulfuric acid (H 2 SO 4 ) are mixed they react to produce silver sulfate and nitric acid (HNO 3 ). a. Write a balanced chemical equation for this reaction. b. Write the net ionic equation for the formation of the solid. c. When 53.3 mL of AgNO 3 solution were mixed with an excess of H 2 SO 4 , 12.5 g of Ag 2 SO 4 were produced. What is the molarity of the AgNO 3 solution? 7. Consider the equation for the reaction of sodium and nitrogen to form sodium nitride: 6Na(s) + N 2 (g) b 2Na 3 N(s) a. If 80.0 g of sodium is mixed with 20.0 g of nitrogen gas, what mass of sodium nitride forms? b. If the reaction in part (a) has a percent yield of 75.0%, how much sodium nitride is actually produced in the reaction?...
