Let's acidify some phosphorous. Figure out how many grams of SO2you could theoretically produce if you start with 2.3 moles of P and 3.6 moles of H2SO4. Reaction: 2P + 5H2SO4--> 2H3PO4+ 5SO2+ 2H2O. You must show all work clearly and in detail to receive credit. All numbers seen immediately following the elemental symbols are intended to be subscripts.
The students continued to do the experiment and determined the negative heat capacity of a metal and heats of reaction, using the negative heat capacity for the calorimeter.
Suppose that the observed melting point range of a solid was originally 150-160 °C, but this became 145-145.5 °C after recrystallization. How might you account for this observation

an acetic acid solution of 2.87 pH is titrated with 1.5 mL of bromocresol green. When the color changes to light green, the pH is 3.95. The final color of the solution is dark blue.
During the course of an experiment, 10.0 mL of water is added to 25.0 mL of aqueous 0.120 M NaCl. What is the concentration of NaCl in the resulting solution
In the Hofmann Degradation of amines an amine is exhaustively methylated with Methyl Iodide and the resultant compound treated with Silver Hydroxide and heated. An alkene is formed which is not the Saytzeff product.
Calculate the systematic treatment of equilibrium. Remember C2O4^2- is a weak base so you must consider other equilibria. (Ksp(ZnC2O4)=7.5X10^-9, Kb1=1.8X10^-10, Kb2=1.8X10^-13). Solve using systematic treatment of equilibrium.

The solubility product for barium sulfate is 1.10x10-10. Calculate ?G° in kJ/mol at 298 K. Report your answer with one decimal point.
Sn2 requires a strong nucleophile while E2 requires a strong base. But relatively compared if you have a very strong base the E2 is preferred. Why is it so?
