1)The Ksp of mercury(II) hydroxide, Hg(OH)2, is 3.60 × 10-26. Calculate the solubility of this compound in g/L.Gf of H2CO3 = -616.1 KJ/mol Gf of H20 = -237.1 KJ/mol Gf of CO2 = - 394.4 KJ/mol 2.A) Carbon dioxide dissolves in water to form carbonic acid. Estimate the thermodynamic equilibrium constant for this reaction using the ΔGf° values shown here.2.B) Carbonic acid then ionizes in water (Ka1 = 4.5× 10-7). Ignoring Ka2, estimate K for the overall process by which CO2 and H2O form H and HCO3-.2.C) What is the pressure of CO2 in equilibrium with carbonated water at 25 °C and pH = 4.57?3) The free energy generated by ion movement in the cell is used by the cell to do work. Compute the minimum number of millimoles of sodium that would be needed to pump one millimole of calcium ions if the following concentrations were present in the cell. Assume the temperature to be 370C and recall that R=0.008314 kJ/mol-K.Na+(aq, 31 mM) -> Na+(aq, 9 mM)Ca2+(aq, 12 mM) -> Ca2+(aq, 800 mM)
