What is the molar solubility of AgCl in 0.30 M NH3? Ksp for AgCl is 1.8 x 10^-10 and Kf for Ag(NH3)2+ is 1.7 x 10^7.
The complete combustion of 1.076g of C9H8O in a bomb calorimeter ( Cccalorimeter=3.895 kJ/ degree C) produced an increase in temperature of 11.21C. Calculate the molar enthalpy of combustion in kJ/mol.
The normal boiling point of the liquid is 425 K. Liquid, X, and Y are all in equilibrium at 342 K and 1800 bar. Tc = 571K, Pc= 46 bar
the molar enthalpy of vaporization of water at 373 k and 1.00 atm is 40.7 kjmol. what fraction of this energy is used
what is the maximum amount of sodium chloride that can be separated at 25 ºC by filtration, and what is the mass percentage of sodium chloride in the filtrate?
During the synthesis of methyl 3-nitrobenzoate, when the reaction mixture is poured on ice, the product separates out as a solid. Why
Indicate whether or not, each has a fixed shape or fixed volume. In addition, include their relative kinetic energies. Pictures can be drawn to assist in the explanation.
For gases, the canonical partition function, Q, is related to the molecular partition function q by Q = q^N/N!. Use the expression for q and general thermodynamic relations to derive the perfect gas law pV = nRT.
Draw the conformations of 2,2-dimethylbutane looking down the C2-C3 bond clearly labeling the dihedral angle for each conformer. Name eash conformer . Rank all the conformation in descending order from highest to lowest.
At a given temperature, 1.18 atm of F2 and 5.91 atm of Br2 are mixed and allowed to come to equilibrium. The equilibrium pressure of BrF is found to be 1.044 atm. Calculate Kp for the reaction at this temperature. F2(g) + Br2(g) 2 BrF(g)
When optically active propylene oxide is used, the 1,2-diol obtained from the acid hydrolysis has a optical rotation opposite from the Alkaline hydrolysis. Write the mechanism of each hydrolysis that is likely to explain these facts.
The melting of ice requires 1.44 Kcal/mol. If this energy goes into breaking H-bonds, how many H-bonds will there be in liquid water at 0°C?
