A sample of gas contains four gases (He, Ne, Ar and Xe) with the following partial pressures:         He - - 43 mm Hg        Ar ---- 835 mm Hg        Xe ---- 111 mm Hg If the total pressure in the container is 2.0 atm, what is the partial pressure of Ne in the sample? a.  989 mm Hg b.  531 mm Hg c.  366 mm Hg d.  760 mm Hg

Three samples of three different gases are listed in the table below. All the samples contain exactly 1 mole of gas and are at a temperature of -10.0°C. For each sample, decide whether the gas can be reasonably described as an ideal gas. If the gas isn't ideal, decide the most important reason why it isn't. sample A B C pressure (atm) 2.8 1.1 0.86 volume (L) 10.0 20.0 30.0 ideal? O O yes no yes no yes no If not ideal, the most important reason why not: O There are attractions between the particles. The particles don't have zero volume. There are attractions between the particles. The particles don't have zero volume. O There are attractions between the particles. The particles don't have zero volume. X S
