An open flask of air is heated, stoppered in the heated condition, and then allowed to cool back to room temperature. Does the flask contain the same, more, or fewer gas molecules now compared to before it was heated? Is the volume occupied by the gas in the flask approximately the same, greater, or less than before it was heated? Is the pressure in the flask the same, greater, or less than before the flask was heated? Do any of...

Worksheet 8 (Intro) 8. A metal tank contains three gases: oxygen, helium, and nitrogen. If the partial pressures of the three gases the tank are 35 atm of O, 5.0 atm of N2, and 25 atm of He, what is the total pressure inside of the tank? 9. The partial pressure of oxygen gas in a mixture of oxygen and nitrogen gases is 1.02 atm. The total pressure of the mixture is 2.43 atm. Calculate the partial pressure of nitrogen...

In an experiment in the lab, a white solid called ammonium chloride (NH4Cl) is heated and decomposes to form two gases, hydrogen chloride (one hydrogen and one chlorine) and ammonia (one nitrogen and three hydrogens). The reaction is conducted in a closed flask to capture the gases that are produced. Observations from the experiment are recorded below: . . OBSERVATIONS Mass of flask 132.6 g Mass of NH4Cl and flask 153.8 g . Observations of NH4CI: It is a crystalline...

ReviewI Constants Periodic Table The air that surrounds us is mostly empty space, and it can be almost a factor of one thousand less dense than water. Within that mostly empty space, gas molecules are moving around at high speed and colliding with each other, and if you are in an enclosed space, they are also colliding with the walls. We can more easily observe the behavior of a gas by confining it to a container with a known volume,...

In a collision of sufficient force, automobile air bags respond
by electrically triggering the explosive decomposition of sodium
azide (NaN3) to its elements. A 43.398 g sample of
sodium azide was decomposed, and the nitrogen gas generated was
collected over water at 22°C. The total pressure was 798.8 mmHg.

The ideal gas law describes the relationship among the volume of an ideal gas (V), its pressure (P), its absolute temperature (T), and number of moles (n): PV=nRT Under standard conditions, the ideal gas law does a good job of approximating these properties for any gas. However, the ideal gas law does not account for all the properties of real gases such as intermolecular attraction and molecular volume, which become more pronounced at low temperatures and high pressures. The van...
