Shrek is creating swamp gas traps to keep people out of his swamp, he is fictional so he does not use all of the same units as us. The gas canisters he has are pressurized to 377 dragonsbreaths (DB) and have a volume of 2.04 L each. What volume will the gas spread out to cover if he opens them and the gas is now at the atmospheric pressure of 101.3 DB?

Sometimes in lab we collect the gas formed by a chemical reaction over water (see sketch at right). This makes it easy to isolate and measure the amount of gas produced. Suppose the O2 gas evolved by a certain chemical reaction taking place at 35.0°C is collected over water, using an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 48.7mL.   Sketch of a gas-collection apparatus Calculate the mass of O2 that is in the collection tube. Round your answer to 2 significant digits. You can make any normal and reasonable assumption about the reaction conditions and the nature of the gases.   = g

STP (standard temperature and pressure) is used as a reference point for the molar volume of an ideal gas. In the USA, most chemists, most general chemistry texts, and OWL use STP = 0°C, 1 atm, where the molar volume = 22.4 L/mol. If the reference pressure is chosen to be 1 bar, the molar volume is 22.7 L/mol. Do not confuse the two. A 0.580 mol sample of xenon gas occupies a volume of  L at STP.

Sulfur dioxide, a gas that plays a central role in the formation of acid rain is found in the exhaust of automobiles and power plants. Consider a 1.53 L sample of SO2 at a pressure of 5.6 * 103 Pa. If the pressure is changed to 1.5 * 104 Pa, at constant temperature, what will be the new volume of the gas?

Tires are one of the most frequently encountered applications of the gas laws that we never think about. We fill our tires with air, or with nitrogen, but it always works out the same way. Enough gas goes in, the tire inflates, and then the pressure starts going up. In this assignment, we’ll be investigating the ways that the gas laws impact how we treat our tires. Q1. Temperature can have a large impact on gas volumes and pressures. Using your knowledge of the Kinetic Theory of Gases, explain why a very cold morning could cause your car to show a “Low Tire Pressure” warning that goes away over time. It is not enough to say “At low temperatures, the pressure of the gas decreases!”. Make sure to reference what is happening on the particulate level. With your explanation, include two diagrams that show what is happening on the particulate level in the tire at low temperature and at higher (normal) temperatures.

A helium-filled weather balloon has a volume of 636 L at 23.9°C and 751 mmHg. It is released and rises to an altitude of 4.93 km, where the pressure is 484 mmHg and the temperature is –9.1°C. The volume of the balloon at this altitude is _______ L   A sample of oxygen gas at a pressure of 928 and a temperature of 38 C, occupies a volume of 7.72 L. If the gas is heated at constant pressure to a temperature of 66 C, the volume of the gas sample will be  ______ L.   An 1.44 mol sample of argon gas at a temperature of 23.0°C is found to occupy a volume of 28.0 liters. The pressure of this gas sample is _____ atm.     A 1.20 mol sample of argon gas is collected at a pressure of 697 mmHg and a temperature of 15.0°C. The volume of the sample is ______ L.       PLEASE ANSWER ALL THE QUESTIONS IT WAS IN ONE WHOLE QUESTION, THANK YOU!
