Question
ed to raise the tenperatu to raise tRe A12 cm, must be abso your eye by 3.0 °C. Ass e the mass of an eye is 11 g and its specific heat ca ity is 4.0J/s K. L. 65. When the Sojourn pacecraft landed on Mars in 1997, imately 7.8 x 107 km from Earth the planer u it take for the television picture signal to reach Earth from Mars? 66. The most prominent line in the emission spectrum of chromium is found at 425.4 nm. Other lines in the chro- mium spectrum are found at 357.9 nm, 359.3 nm, 360.5 nm, 427.5 nm, 429.0 nm, and 520.8 nm. (a) Which of these lines represents the most energetic light? (b) What color is light of wavelength 425.4 nm? 67, Answer the following questions as a summary quiz on the chapter (a) The quantum number n describes the of an atomic orbital. quantum number energy than a photon of orange light. (b) The shape of an atomic orbital is given by the (c) A photon of green light has(less or more) (d) The maximum number of orbitals that may be asso- ciated with the set of quantum numbers n 4 and (e) The maximum number of orbitals that may be asso ciated with the quantum number set n- 3,e 2, and me-2 is (f) Label each of the following orbital pictures with the appropriate letter:Explanation / Answer
n is called principal quantum number
l is called Azimuthal quantum number
ml is Magnetic quantum number
67)
a)
energy
b)
l (Azimuthal quantum number)
c)
wavelength is less for green than orange
since E = h*c/wavelength
lesser wavelength implies greater energy
Answer: more
d)
n=4 and l=3 is 4f orbital
For given l, the number of orbital = 2l+1
= 2*3+1
= 7
Answer: 7
e)
when n,l,ml is specified, it represents only 1 orbital
Answer: 1
f)
the one with 4 lobes is d
The one which is spherical is s
the one with 2 lobes is p
