The infrared radiation emitted from the CHM 100 student sitting next to you e. The ultraviolet radiation from the lights at the tanning salon
5. To the right is an energy level diagram for an atom of beryllium. (The actual values are not accurate, but that's ok for this question.) How much energy is required to excite a 2s electron to the 3p orbital? (Hint: Be sure to look at the units of the axis very carefully) a. 13.67x10 J Energy/10-19 J b. 5.20x10" J c. 2.90x10 J d. 13.67 J e. 5.20 J 1.06 f. 2.90 J 0.59 9. This electron transition is impossible -1.24 2p 21. 11 -14.91 18 6. In what type of orbital does the electron described by the following quantum numbers reside? n 3,1-1, m,-1, m,- a. 1s bid c2p d. 3s e. 3p 1. 3d 9. This set of quantum numbers is not allowed.
7. A 1.50 L portion of 0.100 M sutamic acid (HSO,NH) is placed in the bottom of a 10.0L glass lined stainless steel chamber. A dish containing 17 25 g of sold NaNO, is floated on the acid. A thin open-ended U tube containing a pool of liquid mercury is connected to the chamber with a short length of gas sight tubing. When the assembly is prepared as shown, the chamber is gently shaken to overturn the floating dish. The resulting reaction proceeds to completion and retums to room temperature.
