Detailed calculations show that the value of Z e f f for the outermost electrons in Si and Cl atoms is 4.29 and 6.12 +, respectively. (a) What value do you estimate for Zeff experienced by the outermost electron in both Si and Cl by assuming core electrons contribute 1.00 and valence electrons contribute 0.00 to the screening constant? (b) What values do you estimate for Z e f f using Slater's rules? (c) Which approach gives a more accurate estimate of Z e f f (d) Which method of approximation more accurately accounts for the steady increase in Z e f f that occurs upon moving left to right across a period? (e) Predict Z e f f for a valence electron in P, phosphorus, based on the calculations for Si and Cl.

2. Make an ice cube at 1 bar pressure by freezing an amount of liquid water that is 2
cm x 2 cm x 2 cm in volume. The density of liquid water at 0 °C is 1.000 g cm³ and the
density of ice at 0 °C is 0.915 g cm³. Note that this difference in density is the reason
your water pipes burst if they freeze and why you shouldn't forget to take your bottle of
pop out of the freezer if you put it in there to try and cool it down faster.
A. What is the work of expansion upon freezing?
B. Is work done on the system or by the system?
I have a excitation/emission spectra of a quinine standard solution here, and I'm having trouble interpreting it. the red line is emission the blue line is excitation. i'm having trouble interpreting properly. just want to know if there is any evidence of raman or rayleigh peaks in the spectra.
