Question

What is the formula of sodium hypochlorite? NaClO_4 NaClO_2 NaClO NaClO_3 what is the frequency of radiation with a wavelength of 440 nm? 4.95 times 1-^-12 s^-1 1.51 times 10^-27 s^-1 6.81 times 10^5 s^-1 6.81 times 10^14 s^-1 2.02 times 10^-11 s^-1 Using the Bohr energy equation (E = -R_H/n^2) calculate the wavelength in meters of light absorbed by an electron In 3n atom of hydrogen as it moves from n = 3 to n = 6. 1.83 times 10^-7 m 1.65 times 10^-11 m 8.22 times 10^-7 m 1.09 times 10^-6 m 3.28 times 10^-6 m The possible values of the magnetic quantum number. m_i, of a 3p electron are: 0, 1, 2 1, 2, 3 -1, 0, +1 2, 1, 0, -1, -2 none of these

Explanation / Answer

13. Formula of sodium hypochlorite

C) NaClO

14. Frequency v = c/l

                           = 3 x 10^8/440 x 10^-9

                           = 6.81 x 10^14 s-1

Answer : d. 6.81 x 10^14 s-1

15. Energy dE = -2.18 x 10^-18(1/nf^2 - 1/ni^2)

   dE = -21.8 x 10^-18(1/6^2 - 1/3^2)

        = 1.82 x 10^-19 J

wavelength (l) = hc/dE

                        = 6.626 x 10^-34 x 3 x 10^8/1.82 x 10^-19

                        = 1.09 x 10^-6 m

Answer : d. 1.09 x 10^-6 m

16. The possible values for m quantum number for 3p electron would be,

c. -1, 0, +1
