A large sport utility vehicle has a mass of 2500 kg.Calculate the mass of CO2 emitted into the atmosphere upon accelerating the SUV from 0.0 mph to 65.0 mph. Assume that the required energy comes from the combustion of octane (C8H18) with 30% efficiency. (Hint: Use KE = ½ mv2 to calculate the kinetic energy required for the acceleration and pay attention to units).
Which of the following reactions, carried out in a closed container, will result in a reduced total pressure? Select one: O a. CH4(g) + 202(g) → CO2(g) + 2H2O(g) b. 2N20(g) → 2N2(g) + O2(g) c. 2HI(g) → H2(g) + I2(g) O d. 2H2(g) + O2(g) 2H20() e. None of these reactions will result in a pressure reduction.
Calculating the reaction rate of one reactant from that of another Nitric acid is a key industrial chemical, largely used to make fertilizers and explosives. The first step in its synthesis is the oxidation of ammonia. In this reaction, gaseous ammonia reacts with dioxygen gas to produce nitrogen monoxide gas and water. alo Suppose a chemical engineer studying a new catalyst for the oxidation of ammonia reaction finds that 514. liters per second of dioxygen are consumed when the reaction is run at 213. °c and the dioxygen is supplied at 0.64 atm. Calculate the rate at which nitrogen monoxide is being produced. Give your answer in kilograms per second. Round your answer to 2 significant digits. Ar kg x10 S ||
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 .
Calculating the reaction rate of one reactant from that of another The reform reaction between steam and gaseous methane (CH₂) produces "synthesis gas," a mixture of carbon monoxide gas and dihydrogen ges. Synthesis gas is one of the most widely used industrial chemicals, and is the major industrial source of hydrogen.

Ammonia is among the top ten synthesized compounds. Its many uses include the manufacture of ammonium nitrate and other fertilizers. Ammonia decomposes at high temperatures. In an experiment to explore this behavior, 2.00 moles of gaseous NH3 are sealed in a rigid 1-liter vessel. The vessel is heated at 800 K and some of the NH3 decomposes in the following reaction: 2NH3(g) <--> N2(g)+3H2(g) The system eventually reaches equilibrium and is found to contain 1.74 mole of NH3.
