pre lab question:

1. Assume for the moment that air consists of 80.00% nitrogen (N₂) and 20.00% oxygen (O₂) by volume. Use these figures and typical values for temperature and pressure (1.000 atm and 25.00°C) to calculate the density of air in g/L.

2. Explain how you will determine the mass of CO₂ gas in your flask.

3. This experiment will require you to know the volume of the air/gas present in your flask. How will you measure this volume?

4. If you are use a graduated cylinder with markings in increments of 0.2 mL to measure liquids, you should interpolate and record volume readings to the nearest what?

While the majority component of air is nitrogen (N2), the gas is very unreactive because of its stability due to the triple bonds that hold the nitrogen atoms together. Nitrogen gas is, therefore, relatively unavailable for chemical reactions. One of the few ways to “fix” nitrogen, making a nitrogen compound from the elemental nitrogen in the atmosphere, is the Haber process (aka Haber - Bosch process). In this reaction, nitrogen gas combines with hydrogen gas to yield ammonia. The enthalpy...
