A. Predict the delta H, delta S, delta V and delta G for dissolving 60. g benzene (C6H6) in 100. g of toluene (C7H8) at 298 K. State any assumptions made.
B. At 20 degrees C, 0.164 mg of H2 dissolves in 100.0 g of water when the H2 pressure above the water is 1.000 atm. Find the Henry's law constant for H2 is water at 20 degrees C.
synthesize benzocaine from benzene. please explain in detail in only three steps how to achieve this reaction. list NMR, MS and IR peaks for each step.
the specific heat of H2O(s) is 2.09 J/g ?C, of H2O (l) is 4.184 J/g ?C, and of H2O (g) is 1.84 J/g ? C. The heat of fusion of water is 334.7 J/g and the heat of vaporization is 2259.4 J/g.
