Chapter 15, Problem 2P

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.

Give the major product of the following reaction. excess 1. OH, H₂O 1.OH H CH3CH2CH21 H 2. A.-H₂O Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default.

2. Use Hess's law to calculate the AH (in kJ) for: rxn CIF(g) + F2(g) → CIF 3 (1) using the following information: 2CIF(g) + O2(g) → Cl₂O(g) + OF 2(g) AH = 167.5 kJ ΔΗ 2F2 (g) + O2(g) → 2 OF 2(g) 2C1F3 (1) + 202(g) → Cl₂O(g) + 3 OF 2(g) о = = -43.5 kJ AH = 394.1kJ

ci Draw the major product(s) of the following reactions: (3 pts) CH3 HNO3/H2SO4 HNO3/ H2SO4 OCH3 (1 pts)

Provide the product for the reaction
