A 26.4 mL of ethylene gas, C2H4, has a pressure of 2.50 atm at 2.50C. If the volume is increased to 36.2 mL and the temperature is raised to 10OC, what is the new pressure?

Consider 4.40 LL of a gas at 365 mmHgmmHg and 20. ∘C∘C . If the container is compressed to 2.40 LL and the temperature is increased to 33 ∘C∘C , what is the new pressure, P2P2P_2, inside the container? Assume no change in the amount of gas inside the cylinder.

For many purposes we can treat propane (C₂Hg) as an ideal gas at temperatures above its boiling point of -42. °C. Suppose the temperature of a sample of propane gas is lowered from 21.0 °C to -24.0 °C, and at the same time the pressure is changed. If the initial pressure was 0.34 kPa and the volume decreased by 55.0%, what is the final pressure? Round your answer to the correct number of significant digits. kPa X Ś

A sample of methane occupied 18.95 L at 41.03 °C. When the volume changed to 11.60 L at 16.59 °C, the pressure was 2.044 atm. Calculate the original pressure (atm). Write out the problem on paper in order to answer the questions related to the setup and the calculation for this problem. Identify all of the terms in this problem and enter the numerical values (without units) in the appropriate blanks. Convert temperature(s) to K, and enter with proper s.f.

A gas sample originally occupies 436 mL at 24 °C. When the volume is expanded to 612 mL and the temperature is increased to 97 °C, the pressure becomes 526 mm Hg. What was the original pressure?

Oxygen gas can be prepared by heating potassium chlorate according to the following equation: 2KC103 (8) 2KCl(s) + 302(g) The product gas, O2, is collected over water at a temperature of 20 °C and a pressure of 757.0 mm Hg. If the wet O₂ gas formed occupies a volume of 5.22 L, the number of moles of KCIO, reacted was 5.3 mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.

A 15.9 mL sample of liquid ethanol (C₂H5OH, density = 0.789 g/mL) was injected into a 10.0 L cylinder containing O₂ at a pressure of 4.50 atm and a temperature of 25 °C. The cylinder was heated to 125 °C and a spark was used to ignite the ethanol, which was completely combusted. What was the final total pressure in the cylinder (in atm) after the reaction, while it was still at 125 °C?

For many purposes we can treat butane (C,H10) : as an ideal gas at temperatures above its boiling point of – 1. °C. Suppose the pressure on a 43.0 g sample of butane gas at 14.0°C is reduced to one-third its initial value. Oyes Is it possible to change the temperature of the butane at the same time such that the volume of the gas doesn't change? к10 no If you answered yes, calculate the new temperature of the gas. Round your answer to the nearest °C.

For many purposes we can treat ammonia (NH3). as an ideal gas at temperatures above its boiling point of -33. °C. Suppose the pressure on a 6.0 m³ sample of ammonia gas at -14.0°C is doubled. Is it possible to change the temperature of the ammonia at the same time such that the volume of the gas doesn't change? If you answered yes, calculate the new temperature of the gas. Round your answer to the nearest °C. yes no пос x10 X

For many purposes we can treat nitrogen (N₂) as an ideal gas at temperatures above its boiling point of −196. °C. Suppose the temperature of a sample of nitrogen gas is lowered from 99.0 °C to 80.0 °C, and at the same time the pressure is increased by 5.0%. Does the volume of the sample increase, decrease, or stay the same? If you said the volume increases or decreases, calculate the percentage change in the volume.
