You are asked to design an air bag for a car. You know that the bag should be filled with gas with a pressure higher than atmospheric pressure, say 838 mm Hg, at a temperature of 22.0 °C. The bag has a volume of 41.5 L. What quantity of sodium azide, NaN3, should be used to generate the required quantity of gas? The gas-producing reaction is 2 NaN3(s) → 2 Na(s) + 3 N2(g) ____ g

The Haber-Bosch process is a very important industrial process. In the Haber-Bosch process, hydrogen gas reacts with nitrogen gas to produce ammonia according to the equation 3H₂(g) + N₂ (g)→2NH3(g) The ammonia produced in the Haber-Bosch process has a wide range of uses, from fertilizer to pharmaceuticals. However, the production of ammonia is difficult, resulting in lower yields than those predicted the chemical equation. 1.56 g H₂ is allowed to react with 10.1 g N₂, producing 2.25 g NH3.

Some commercial drain cleaners use a mixture of sodium hydroxide and aluminum powder. When the solid mixture is poured into the drain and dissolves, a reaction ensues that produces hydrogen gas: 2NAOH(aq) + 2AI(s) + 6H20() → 2NAAI(OH)4(aq) + 3H2(g) Determine the volume (in L) of hydrogen gas produced when 18.77 g of aluminum reacts with excess sodium hydroxide and water if the temperature is 29.59 °C and the pressure is 106.79 kPa. Provide your answer with TWO decimals. Your Answer: Answer units

Excess sodium bicarbonate (NaHCO3) is added to a 250. mL solution sulfuric acid (H2SO4). The sodium bicarbonate the sulfuric acid react as shown below, producing liquid water, carbon dioxide gas and aqueous sodium sulfate. 1 H2SO4 (aq) + 2 NaHCO3 (s) → 2 H20 (I) + 2 CO2 (g) +1 NazSO4(aq) The temperature is 29.°C, and the volume of gas produced, collected in an inverted cylinder over water, is 175. mL. Assume this reaction goes to completion. If the total pressure inside the inverted cylinder at the end of the reaction is 316 torr, what was the molarity of the sulfuric acid solution?
