In the Alka-Seltzer reaction, 19.76 mL of carbon dioxide are measured.  The partial pressure of carbon dioxide is 0.903 atm, the temperature is 24.4°C.  What is the moles of carbon dioxide?

Consider a gas sample in a closed 5.0 liter cylinder at a pressure of 1.2 atm. If the volume of the cylinder is expanded to 17.0 liters, what will the pressure inside the cylinder be? Assume that T and n stay constant.

A sample of gas contains 0.1700 mol of CH4(g) and 0.1700 mol of H2O(g) and occupies a volume of 19.2 L. The following reaction takes place:CH4(g) + H2O(g)3H2(g) + CO(g)Calculate the volume of the sample after the reaction takes place, assuming that the temperature and the pressure remain constant.

How many grams of iron are needed to completely consume 36.4 L of chlorine gas according to the following reaction at 25 °C and 1 atm?iron ( s ) + chlorine ( g )  iron(III) chloride ( s )

A mixture of nitrogen and xenon gases, in a 5.99 L flask at 50 °C, contains 2.90 grams of nitrogen and 43.1 grams of xenon. The partial pressure of xenon in the flask is atm and the total pressure in the flask is atm.

2. The pressure inside a 4.00 L cylinder of gas is 1.808 atm. If the gas was comnpressed to a pressure of 440.0 kPa, what would its volume become? (Assume constant T). Note: 1 atm= 101.325 kPa

A mixture of helium and carbon dioxide gases, in a 7.08 L flask at 81 °C, contains 1.17 grams of helium and 6.24 grams of carbon dioxide. The partial pressure of carbon dioxide in the flask is  atm and the total pressure in the flask is  atm.

A 6.906 g sample of dintrogen pentaoxide gas in a 275 mL container at 35°C has a pressure of atm.

Combustion of hydrocarbons such as pentane (C5H12) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. A.) suppose 0.100 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 13°C. Calculate the volume of carbon dioxide gas that is produced. Round your answer to three significant digits.
