(WCSU24) We often use theory (valence bond, hybridization, resonance, etc.) to explain experimental data. When resonance (delocalized pi bonding) is present in a structure, what you see is not always what you get. In the structure shown, the bond angles about nitrogen are 120 degrees. Based on this information, give the following information: a. Molecular geometry about the nitrogen atom: [blank1] b. Hybridization of the nitrogen atom: [blank2] c. Name type of orbital holds the lone pair: [blank3]

(WCSU24) Each of the following transitions is from a different series (i.e. Balmer, Lyman, etc.) of emission lines from the hydrogen atom. NO CALCULATIONS ARE NECESSARY! 🙂 a. n = 10 to n = 5 b. n = 5 to n = 2 c. n = 3 to n = 2 d. n = 2 to n = 1 i. Which transition will be the smallest change in energy? [drop1] ii. Which transition will have the shortest wavelength? [drop2]

(WCSU24) Shown below are five curves that represent the distribution of molecular speeds of five different gases at the same temperature and pressure, each in a separate 10 L container. The gases are H2, CH4, He, SF6, and N2. Complete the statements so that they are true. a. The gas represented by [drop1] has the largest fraction of molecules traveling at the most probable speed. b. Curve [drop2] corresponds to N2. c. All of the gases represented have the same [drop3]. d. Gas [drop4] has the greatest density. e. Increasing the speed of the molecules will [drop5] the pressure.
