For many purposes we can treat methane (CH₂) as an ideal gas at temperatures above its boiling point of -161. °C. Suppose the temperature of a sample of methane gas is raised from -69.0 °C to -38.0 °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? O increase O decrease O stays the same If you said the volume increases or decreases, calculate the percentage change in % the volume. Round your answer to the nearest percent. 0 x10

12. The pressure of a gas sample at 60.0 °C is decreased from 3.40 atm to 2.60 atm by cooling at a constant volume. What is the temperature (in °C) of the gas at 2.60 atm?

e to search For many purposes we can treat propane (C3H₂) 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 24.0 °C to -18.0 °C, and at the same time the pressure is changed. If the initial pressure was 7.1 atm and the volume increased by 45.0%, what is the final pressure?

For many purposes we can treat ammonia (NH3) a Suppose the pressure on a 590. mL sample of ammonia gas at 9.00°C is doubled. as an ideal gas at temperatures above its boiling point of -33. °C. 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 O no C 0 x10 X S

The stopcock connecting a 4.44 L bulb containing carbon dioxide gas at a pressure of 8.24 atm, and a 6.17 L bulb containing neon gas at a pressure of 4.32 atm, is opened and the gases are allowed to mix. Assuming that the temperature remains constant, the final pressure in the system is  atm.

For many purposes we can treat propane (C,H,) a as an ideal gas at temperatures above its boiling point of -42. "C. Suppose the temperature of a sample of propane gas is raised from 90.0 °C to 144.0 °C, and at the same time the pressure is increased by 10.0%. Does the volume of the sample increase, decrease, or stay the same? O increase O decrease O stays the same If you said the volume increases or decreases, calculate the percentage change in % the Round your answer to the percent X

O Consider the Ideal Gas Law. Suppose the volume and amount of gas are held constant. If the pressure is increased from 1 atm to 3 atm, and the original temperature is 27° C, what will be the new temperature?

A. an experiment was done to determine the value of the ideal gas constant( R). hydrogen gas was generated and collected at a given temperature and pressure 1.44X 10 ^-3 moles of hydrogen gas occupied 35.9 mL at 758.0 MMHG and 23.2 Celsius based on these values, calculate the experimentally determine value of R (L x atm/mol x K). B. Using the ungrounded number for the previous problem determine the percent error for the experimentally determined value of R.
