Question

1. Hydrogen gas, H2, reacts with nitrogen gas, N2, to form ammonia gas, NH3, according to the equation: 3 H2(g) + N2(g) → 2 NH3(2) - How many grams of H2 are needed to produce 14.43 g of NH3? 2. When propane (C2H8) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is... CzHz (g) + O2(g) → CO2(g) + H2O(g) This type of reaction is referred to as a complete combustion reaction. What coefficients are needed to balance the equation for the complete combustion of propane? Enter the coefficients in the order C3 respectively. Express your answer as four integers, separated by commas (e.g., 1,2,3,4). 3. 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: 3 H2(g) + N2(g) → 2 NH3 (3) 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 from the chemical equation. What is the maximum theoretical yield in grams if 1.51 g H2 is allowed to react with 10.1 g N2?
