For many purposes we can treat methane (CH,) as an ideal gas at temperatures above Its bolling point of-161. °C. Suppose the temperature of a sample of methane gas is ralsed from -21.0 °C to 13.0 °C, and at the same time the pressure is changed. If the Initlal pressure was 2.8 atm and the volume Increased by 30.0%, what is the final pressure? Round your answer to the correct number of significant digits. atm x10

By volume, dry air is 78% N2, 21% O2 and 1% Ar. What is the partial pressure of each of these components in air at a pressure of 1.00 atm?
For many purposes we can treat dimethyl ether (C₂H₂O) as an ideal gas at temperatures above its boiling point of -24. °C. Suppose the pressure on a 15.0 g sample of dimethyl ether gas at - 12.0°C is cut in half. Is it possible to change the temperature of the dimethyl ether 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 [°C x10 X Ś

When collecting a gas over water it is necessary to correct for the vapor pressure of water in order to determine the pressure of the gas you are collecting. We will do this by using a graph of ln P in mmHg versus 1/T where T is the temperature in Kelvin. The equation is y = -5206.4 x + 20.621 (With an R^2 = 0.9999). If you collect a gas at 26.8 ℃, what is the value of “x” that you want to use in the equation. (Keep the answer for the next question).
