Unformatted text preview: State clearly your conclusion. (7 pts) Rh is a d 7 transition metal: ↑↓ ↑↓ ↑ ↑ ↑ Unpaired electrons so paramagnetic 5) Give a CONDENSED electron configuration for a Nickel (II) ion (5 pts) [Ar]3d 8 1 2 3 12) Provide a correct Lewis Structure for nitric acid, include all resonance structures and a sketch of the resonance hybrid. (10 pts) 13) Calculate the average wavelength of a He atom in a sample of He gas at 0.005 atm and 100.0 K. In other words, what is the wavelength of the average He atom in the sample? (10 pts) v rms = sqrt(3RT/M) = sqrt(3*8.314*100/0.004) = 789.7 m/s Convert molar mass to mass of one He Atom Mass = Molar mass/N A = 0.004/6.02x10 23 = 6.64x1027 λ = h/(mv) = 6.626x1034 /(6.64x1027 * 789.7) = 1.2x1010 meters 4...
