Derive a relation for ( hint: Maxwell's relations will be helpful) to determine how entropy will change with pressure at constant temperature (δS/δp)t for a gas that behaves according to the following equation of state PV = nRT/a + P/b, where a and b are empirically determined constants for a given gas.
Integrate your solution to solve for an equation for ?S and answer the following question.
Suppose that 22.65 mL of a 0.02024 M permanganate solution (KMnO4) was needed to react with the Fe2+ in a sample that had a mass of 1.1243 g. What is the mass of the Fe2+ in the sample and what is the % of Fe2+ in the sample
the chromatographic paper in the spot testing chromatogram. predict the effect of this procedural change on the solution of the cation in the standard mixture
After the label fell off a bottle containing a clear liquid believed to be benzene, a chemist measured the density of the liquid to verify its identity. A 25.0-{\rm mL} portion of the liquid had a mass of 21.95 {\rm g}. A chemistry handbook lists the..
What is the equilibrium concentration of chloroacetic acid, HC2H2O2Cl, in a solution prepared by dissolving 0.0277 mol of HC2H2O2Cl in 1.00 L of water

Looking at the nickel complexes as an example, it is found that those formed with ammonia give the complex [Ni(NH3)6]^2+ and when formed with ethylenediamine the complex [Ni(en)3)^2+ is the result.
predict the ratio of the two masses of oxygen that combine with a fixed mass of lead to form PbO and PbO2? PbO:PbO2 oxygen mass ratio= ?/?
An evaluation of R was performed, following the procedure described in this module. The barometric pressure was 736 torr, the temperature was 295k and volume of hydrogen gas collected was 35.6 mL. The calculated value of R was 82.1 mL atm K^-1 mol..
Above 300 degrees C, ammonium nitrate decomposes to N2, O2, and H2O. Write a balanced chemical reaction describing the decomposition of ammonium nitrate, and determine the standard heat of reaction by using the appropriate enthalpies of formation.
Calculate the molar mass of maltose (which is not an ionic compound). (b) The density of the solution is 1.014 g/mL. Calculate the osmotic pressure of the solution.
The latest techniques in microspectroscopy are capable of detecting fluorescent molecules in volumes limited only by the spatial resolution of the microscope, as small as (1μm)3 . if a 2 micromolar (2μM) solution is sampled by such a microscope
Every living organism is unique because of its genetic code. Organisms may look like each other physically or have the same physiological abilities
