10) Hydrocarbons are organic compounds consisting of hydrogen and carbon only. Burning hydrocarbons in the presence of oxygen, O2, produces carbon She oxide, CO₂, and water, H₂O. Methane, CH4, is a hydrocarbon used primarily as fuel to make heat and light. The overall reaction of a number of such steps of methane gas is: CH4(g) + O2(g) + NO(g) → CO2(g) + H2O(g) + NO2(g) + OH(g) Suppose that 3.92 L of methane at STP, 10.8 L of oxygen at STP, and 8.3 L of nitrogen monoxide at STP were combined in a 7.0 L flask. The reaction is allowed the stand for several weeks at 275 K. If the reaction reaches 79.5% of completion, what is the total pressure in the flask? What is the partial pressure of CH4(g) and H2O(g) in the flask?

There are two steps in the extraction of copper metal from chalcocite, a copper ore. In the first step, copper(I) sulfide and oxygen react to form copper(I) oxide and sulfur dioxide: 2Cu,S(s) 30,(8) 2Cu,0(s) + 2 SO, (g) In the second step, copper(I) oxide and carbon react to form copper and carbon monoxide: Cu,O(s) + C(s) 2Cu(s) + Co (g) Suppose the yield of the first step is 84.% and the yield of the second step is 95.%.

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.

Suppose a pair of chemical compounds A and B can react in two different ways: A+B C Reaction 1 gives product C. A+B D →> Reaction 2 gives product D. The following facts are known about the two reactions: • Reaction 1 is endothermic and Reaction 2 is exothermic. • If a reaction vessel is charged ("filled") with A and B, then at first C is produced faster than D. Use these facts to sketch a qualitative reaction energy diagram for both reactions. Note: because these sketches are only qualitative, the energies don't have to be exact. They only have to have the right relationship to each other. For if one energy is less than another, that fact should be clear in your sketch. energy A + B Reaction 1 reaction coordinate energy A + B Reaction 2 reaction coordinate ☑
