What partial-derivative relation can you derive from the thermodynamic identity by considering a process that takes place at constant entropy? Does the resulting equation agree with what you already knew? Explain.
Cholesterol in blood is measured in milligrams of cholesterol per deciliter of blood. If the average adult has 6.0 liters of blood, how many grams of cholesterol would be in the blood of an average adult with a cholesterol reading of 185 mg/dL? Densi..
The thallium (present as Tl2SO4) in a 9.043 g pesticide sample was precipitated as thallium(I) iodide. Calculate the mass percent of Tl2SO4 in the sample if 0.3524 g of TlI was recovered.
Analysis of water in a sediment sample at equilibrium at pH 7.00 showed [SO42-] = 2.00 x 10^-5 M and a partial pressure of H2S of 0.100 atm. Show with appropriate calculations if methane, CH4, would be expected in the sediment.
A gaseous hydrocarbon with the empirical formula CH2 was placed in a 2.00L container. At a temperature of 101oC the pressure was 755 Torr and the mass of the hydrocarbon was 1.812g. What are the values of the integer a and b for this molecular for..
Presume that when determining the volume of a pycnometer a student didn't notice there were air bubbles inside the pycnometer when it was filled with water. Explain what effect would this have on the determination of the pycnometer's volume
