Example 1: If a 2.0 L sample of air is collected at 298K, but its temperature falls to -25°C, what is the final volume of the sample?

11. At an altitude of 40 km above the earth's surface, the atmospheric pressure is 5.00 torr, and the surrounding temperature is -20°C. If a weather balloon is filled with 1.000 mol of He at 760 torr and 22°C, what is its a. initial volume before ascent? b. final volume when it reaches 40 km in altitude? (Assume the pressure of the gas equals the surrounding pressure.)

The reaction of hydrogen gas with oxygen gas is likely responsible for the Hindenburg disaster in 1937, when a airship filled with hydrogen gas ignited and burned, killing 37 people. If 965.3 g of oxygen gas reacts completely with hydrogen gas, what volume of water vapor will be produced (in L) at 0.6661 atm and 8.40°C ? Write the balanced equation to help you solve this problem. Give your answer to 4 sig figs!

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. collected gas chemical reaction water Suppose the CÓ gas evolved by a certain chemical reaction taking place at 30.0 °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 131. mL. Sketch of a gas-collection apparatus alo Calculate the mass of CO 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. Explanation Check O 2022 McGraw Hill LLC. All Rights Reserved.

When 35.6 L of ammonia and 40.5 L of oxygen gas burn at STP, gaseous nitrogen monoxide and water vapor form. When the products return to STP how many grams of nitrogen monoxide are present?

A sample of oxygen is collected over water and has a volume of 6.19 ml. The pressure of the collected "wet" gas is 67.27 kPa and the temperature is 20°C. What will the volume of the "dry" oxygen be in mL if the pressure is changed to 91.56 kPa and the temperature is changed to -22.5°C? (The Vapor pressure of water at 20°C is 2.333 kPa) (Answer to two decimal places and no units in your answer)
