One of the steps to sweeten sour gas using the Claus process is reacting hydrogen sulfide gas with sulfur dioxide gas to produce water vapour and sulfur.

A mixture of methane (CH₄) and butane (C₄H₁₀) at one atmosphere pressure and 25°C has a density of 1.639 g/L. Assuming ideal behavior, what is the mass in grams of carbon that are in 1 liter of the mixture?

Gaseous mixture: 0.943 g air (0.006846 mol O2 and 0.025754 mol N2) 0.0641 g gas (5.05 x 10^-4 mol isooctane and 1.39 x 10^-4 mol ethanol)  In “the intake stroke”, the air/C8H18 gaseous mixture in Question 3 is transferred into the cylinder, where the piston reaches the bottom of the cylinder.  Assume the gas mixture an ideal gas behavior, the temperature of cylinder is 212 oF, and the total pressure of gas mixture is 1.00 atm, Calculate moles of C8H18, O2 and the total moles of air/fuel mixture?

Long-term space missions require reclamation of the oxygen in the carbon dioxide exhaled by the crew. In one method of reclamation, 1.00 mol of carbon dioxide produces 1.00 mol of oxygen, with 1.00 mol of methane as a by-product. The methane is stored in a tank under pressure and is available to control the attitude of the spacecraft by controlled venting. A single astronaut exhales 1.03 kg of carbon dioxide each day. If the methane generated in the recycling of three astronauts' respiration during one week of flight is stored in an originally empty 140-L tank at −45.0°C, what is the final pressure in the tank?

Upon heating CaCO3 (s), carbon dioxide (CO2) is produced is produced. After cooling the gas to 25 °C, the CO2 (g) pressure is measured using a manometer by comparing the difference in the heights of the mercury (Ah), where Ah equals 248.6 mm. What is the pressure of the CO2 gas in atmosphere units? Answer format: • Calculate your answer in units of atmosphere • Enter the number only; do not include units. • Provide your answer to three decimal places.

A cylinder measuring 9.7 cm wide and 12. cm high is filled with gas and the piston pushed down with a steady force. piston gas KN cylinder Calculate the force on the piston if the pressure in the gas is measured to be 706. kPa. Write your answer in units of kilonewtons. Be sure your answer has the correct number of significant digits. x10 X Ś

A marine biologist is preparing a deep-sea submersible for a dive. The sub stores breathing air under high pressure in a spherical air tank that measures  69.0 cm wide.The biologist estimates she will need  3900L of air for the dive. Calculate the pressure to which this volume of air must be compressed in order to fit into the air tank. Write your answer in atmospheres. Round your answer to  3 significant digits.
