Based on the following equation, how many liters of NH3 can be produced from 15 liters of H2 at constant temperature and pressure? (use appropriate units in any conversions) N2(g) + 3H2(g) ⟶ 2NH3(g)
Nitrogen forms a surprising number of compounds with oxygen. A number of these, often given the collective symbol NOx (for "nitrogen + x oxygens") are serious contributors to air pollution. They can often be interconverted, sometimes by reaction with oxygen or ozone (O3) in the air. An atmospheric scientist decides to study the reaction between nitrogen trioxide and oxygen that produces nitrogen dioxide and ozone. He fills a stainless steel reaction chamber with 7.9atm of nitrogen trioxide gas and 1.7atm of oxygen gas and raises the temperature considerably. At equilibrium he measures the mole fraction of nitrogen dioxide to be 0.14. Calculate the pressure equilibrium constant Kp for the equilibrium between nitrogen trioxide, oxygen, nitrogen dioxide and ozone at the final temperature of the mixture. Round your answer to 2 significant digits.
The human body burns glucose (C6H12O6) for energy according to this chemical reaction: C6H12O6+6O2→ 6CO2+6H2O The products of the reaction are carbon dioxide CO2 and water H2O Interestingly, all of the carbon dioxide and much of the water exits the body through the lungs: on every breath, the average person exhales 500.mL of air, which is typically enriched to 4% CO2 and 5% water vapor by volume. In short, when a person loses weight by dieting, the weight that is lost actually departs his body as a gas, every time he exhales. Each kilogram of body fat lost requires exhaling about 2.9kg of carbon dioxide. Calculate how many breaths it takes an average person to "exhale" 0.50kg of fat. Round your answer to the nearest thousand. You'll need to know that the density of CO2 is 2.0 kg/m^3 .
