Unformatted text preview: Presented By Preceptors Chemistry 151 Exam 2 Review 2 Seung Attack weapons using lasers most likely will use high energy photons like X-rays. If an X-ray has frequency of 3.0x10 +18 Hz( 1/sec), The energy of one single photon is E=h . ν What is the energy of one mole of photons of this radiation is: ( h= 6.626 x10-34 Js c= 3.0 x 10 8 m/s) E = hv E = (6.626 x10-34 J.s) x (3.0 x 10 18 1/s) = 1.99 x 10-15 J/Photon (1.99 x 10-15 J/Photon) x (6.022 x 10 23 Photon/mole) = 1.19 x 10 9 J/mole Energy of light SO Wavelength Frequency Energy/photon Energy/mole 1980 nm Hz J/photon J/mole m 93.9 MHz J/photon J/mole Energy of light Some things you should know: E = hv (h = 6.626 * 10-34 Js) ; C = λv SO 1.51 * 10 14 1.01 * 10 -19 60457 3.19 6.22 * 10 -26 .037 (1980 nm) x (10-9 ) = 1.98 * 10-6 m (3.0 * 10 8 m/s) / (1.98 * 10 -6 m) = 1.51 * 10 14 1/s (1.51 * 10 14 m) x (6.626 * 10 -34 Js) = 1.01 * 10 -19 J/photon (1.01 * 10 - 19 J/photon) x (6.022 * 10 23 photons/mol) = 60457 J/mol Which one of the following configurations depicts an excited state of a neutral oxygen atom? a)1s 2 2s 2 2p 2 b)1s 2 2s 2 2p 2 3s 2 c)1s 2 2s 2 2p 1 d)1s 2 2s 2 2p 4 e)[He]2s 2 2p 4 Orbitals The electron configuration of a Co 3+ ion is: a) [Ar]3d 5 b) [Ar]4s 1 3d 5 c) [Ar]4s 2 3d 4 d) [Ar]3d 6 e) [Ar]4s 2 3d 9 SO 1s 2s 2p 3s 3p 4s 3d The ground state electron configuration for Cu +2 is _____. a) [Kr]4s 2 3d 10 b) [Ar]4s 3d 9 c) [Ar]4s 2 3d 9 d) [Ar]3s 2 3d 10 e) [Kr]3s 2 3d 10 Orbitals 1s 2s 2p 3s 3p 4s 3d SO Orbitals Write the electronic configuration ( 1s 1 2s 2 2p 6 etc.) for a single atom of Titanium (element 22)...
