A student (Sam) is helping a friend (Devin) solve a stoichiometry problem. Devin needs to know how many liters of nitrogen monoxide (NO) gas are created at STP when 32.2 g of solid copper reacts with excess nitric acid. 3Cu(s) + 8HNO3(aq) → 3Cu(NO3), (aq) + 4H2O(1) + 2NO(g) Devin knows they should put 32.2 g Cu down first, and they also know they need to convert from grams to something else. Sam provides a clue to Devin: they will need 3 conversion factors (which are empty, below). What does Devin need in order to complete the second conversion factor? 32.2 g Cu 1 O Coefficients from the balanced equation (molar ratio) The molar mass of nitrogen monoxide O The molar mass of copper O Avogadro's number O The STP volume of gas (22.4 L/mol)

A commercial 737 jet transporting 143 passengers and 5 crew members from Kansas city (MCI) to Baltimore (BWI) burned 11800 lb. of Jet A fuel. Jet A fuel is kerosene based, consisting primarily of CnH2n+2 hydrocarbons, with n = 6 to 16, so the Carbon:Hydrogen ratio is close to 1:2. During this flight , how much CO2 (in kg) was released into the atmosphere? (assume the combustion of fuel was complete, so all fuel was converted into H2O and CO2).
Automakers are always investigating alternative reactions for the generation of gas to inflate air bags, in part because the sodium produced in the decomposition of NaN3 presents safety concerns. One system that has been considered is the oxidation of graphite by strontium nitrate, Sr(NO3)2, as shown in the equation below. 5 C(s) + 2 Sr(NO3)2 (8)→ 2 SrO(s) + 2 N₂(g) + 5 CO₂(g) Suppose that a system is being designed using this reaction, and the goal is to generate enough gas to inflate a bag to 63 L and 1.4 atm at 23°C. What is the minimum mass of graphite that should be used in the design of this system? g C(s)
