Concept Introduction:
Effusion is explained as movement of the gas molecule through small hole.
Diffusion can be explained as when one gas molecule mix with another gas molecule by random motion.
Graham’s law of effusion gives relation of rate of effusion with molar mass. Rate of effusion and square root of molar mass are inversely related. The mathematical expression is as follows:

(b) Which cylinder contains the greater number of molecules?arrow_forward73. A 500.-mL sample of O2 gas at 24 °C was prepared by decomposing a 3% aqueous solution of hydrogen peroxide, H2 O2, in the presence of a small amount of manganese catalyst by the reaction 2H2 O2 (aq) → 2H2O (g) + The oxygen thus prepared was collected by displacement of water. The total pressure of gas collected was 755 mm Hg. What is the partial pressure of O2 in the mixture? How many moles of O2 are in the mixture?

- Before small batteries were available, carbide lamps were used for bicycle lights. Acetylene gas, C2H2, and solid calcium hydroxide were formed by the reaction of calcium carbide, CaC2, with water. The ignition of the acetylene gas provided the light. Currently, the same lamps are used by some cavers, and calcium carbide is used to produce acetylene for carbide cannons.(a) Outline the steps necessary to answer the following question: What volume of C2H2 at 1.005 atm and 12.2 °C is formed by the reaction of 15.48 g of CaC2 with water?(b) Answer the question.arrow_forwardMass of a vacuumed (empty) vessel of volume 5 L is 640.05 g, and mass of the same vessel filled with this hydrocarbon up to the pressure 2.0 atm at 22oC is 658.23 g.
