Q1.A glass vessel was filled with an unknown quantity of nitrogen gas and the pressure at 28°C was 4.2 x 10⁴Pa. Oxygen gas was introduced at the same temperature until the pressure was to 1.013 ×10⁵Pa.
(I) calculate the partial pressures of nitrogen gas and oxygen gas
(II) calculate the mass ratio of the two gases. ( N=14, O=16)
Q2. When temperature is increased by 10K, what happens to the rate of reaction? Why is it so?
(A) A sample of carbon dioxide gas at a pressure of 1.12 atm and a temperature of 242 °C, occupies a volume of 493 mL. If the gas is heated at constant pressure until its volume is 773 mL, the temperature of the gas sample will be °C. (B) A sample of argon gas at a pressure of 888 mm Hg and a temperature of 25 °C, occupies a volume of 10.5 liters. If the gas is cooled at constant pressure to a temperature of 1 °C, the volume of the gas sample will be L.
The ideal gas law describes the relationship between pressure (P), temperature (T), volume (V), and
the number of moles of gas (n).
PV = nRT
The additional symbol, R, represents the ideal gas constant. The ideal gas law is a good approximation
of the behavior of gases when the pressure is low and the temperature is high. (What constitutes low
pressure and high temperature varies with different gases.) In 1873, Johannes Diderik van der Waals
proposed a modified version of the ideal gas law that better models the behavior of real gases over a
wider range of temperature and pressure.

")(v – nb) = nRT
In this equation the additional variables a and b represent values characteristic of individual gases.

- You have a gas, one of the three known phosphorus-fluorine compounds (PF3, PF3, and P2F4). To find out which, you have decided to measure its molar mass. (a) First, yon determine that the density of the gas is 5.60 g/L at a pressure of 0.971 atm and a temperature of 18.2 C. Calculate the molar mass and identify the compound. (b) To check the results from part (a), you decide to measure the molar mass based on the relative rales of effusion of the unknown gas and CO2. You find that CO2 effuses at a rate of 0.050 mol/min, whereas the unknown phosphorus fluoride effuses at a rate of 0.028 mol/min. Calculate the molar mass of the unknown gas based on these results.arrow_forward109 An ore sample with a mass of 670 kg contains 27.7% magnesium carbonate, MgCO3.
