Lab 7: Gas Law Pre-Lab Questions 3. Your cousin made a bad life choice and went to Dominican College instead of STAC. He is also taking General Chemistry Lab this semester. Instead of reacting Mg with HCl, he is supposed to react zinc, Zn with HCl and performed a similar experiment. He reacted a 0.063 g sample of zinc with excess 1 M HCl at 24 °C (both lab and water temperature). The reaction produced a gas that expanded to a volume of 25.0 mL. The atmospheric pressure was 760 mmHg on the day he performed the experiment. a. Write the balanced equation for this reaction. CI Name: b. What is the pressure (in atm) of the H₂ gas that was produced? Remember to take into account the vapor pressure of water. c. What is the temperature in Kelvin? d. How many moles of H₂ should you produce with this amount of starting material? e. Using the P, V, T, and n listed above, solve for your experimentally determined value of the Ideal Gas Constant, R.

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).
In 2014, the World Anti-Doping Agency announced that Xenon gas would be added to the list of banned substances for athletes. Apparently since 2004, Russian athletes had been inhaling xenon while training, with the physiological effect being to boost the capacity of blood to carry oxygen needs for aerobically demanding sports. If an athlete inhaled an average of 1.75 x 10-4 moles of Xe per breath while sleeping, with an average rate of 13.0 breaths per minute for 8.50 hours how many total GRAMS of Xe(g) were inhaled while sleeping? please show all calculations

2. Based on what you have learned so far, why is it necessary to stir the water and wait until the end of the video to read the dissolved oxygen? The stirring aerates the water, causing the oxygen to dissolve more easily in the water. The stirring causes oxygen molecules to leave. The stirring causes the H20 to break apart and release oxygen. The stirring causes hydrogen gas to mix with oxygen gas making water.

Ammonium carbamate will decompose into ammonia and carbon dioxide gasas. A 780.7 g sample of ammonium carbamate was allowed to decompose at a certain elevated temperature on a 10.0 L sealed container. A 25.0 mL sample of the headspace gas (i.e. the gas above the solid) was removed, and 0.0545 g ammonia could be isolated from that sample. NH4(NH2CO2)(s) = 2NH3(g) + CO2(g). (a) what cncenteration of ammonia, in mol/L was present in the headspace gas? (b) How many moles of ammonium carbamate had evaporated? Assume that the container volume is in addition to the volume of the solid (0.57 L) and that you may neglect the change in the volume occupied by the solid due to decomposition. (c) Calculate Kc for the decomposition of ammonium carbamate under these conditions.
