Using the following Latimar diagram, calculate the value that would be plotted on the Frost diagram for the NH4+ species. Have your answer to 2 decimal places.

You are asked to make spaghetti. You start boiling the water and find it is taking too long. Your friend suggests that you add salt to the water to speed up the boiling process. a. Based upon the circumstances above, come up with a very specific question you will try to answer through experimentatior b. Based upon knowledge of intermolecular and intramolecular bonding, hypothesize an answer to the question you created. c. Based upon your knowledge of inter and intramolecular bonding, give reasons for your hypothesis. Include diagrams in your explanation d. Design a fair experiment to test your hypothesis

Calculate the value of the force constant for a crystal of sodium chloride if you know that the lattice constant is 2.82 * 10^-10 m, the mass of sodium is 3.8 * 10^-23 gm, the mass of chlorine is 5.9 * 10-23 gm, and their phase speed is 3.4 * 10^-3 m/sec    equal to 3.4x6

The diagram shown below is a theoretical representation of the phase diagram for carbon. The hatched regions indicate conditions under which the phase is predicted to be metastable in effect this means that multiple phases can co-exist in these regions. Using this diagram, answer the following questions concerning the phases of carbon. Note the indicated scales for the horizontal and vertical axes (1 bar = 0.0001 GPa). 1000- 100- p/GPa 10- 0.1 0.01- 0.001+ 0 diamond graphite 1 2 3 4 liquid vapor 5 6 7 T/1000 K 8 9 10 (a) Does graphite melt or sublime at 10 bars of pressure? (b) If pressure remains constant, what are the possible phase transitions for diamond at 4500 K as T is increased? (c) Identify the approximate temperature and pressure of the standard solid-liquid-gas triple point on this diagram. Are there other triple points indicated in the diagram? (d) Estimate the maximum temperature at which graphite can exist at P = 1 GPa. What would happen if the pressure is increased for a…
