3 moles of an ideal gas in an initial state T1 = 300 K and P1 = 0.5 bar undergo an isothermal compression until the pressure of the system is four times the original pressure. The process may occur in two ways:
A) Reversibly.
B) Against a constant external pressure Pext equal to the final pressure P2 of the gas.
For both cases, calculate Delta G in the process.
At 25 oC, experiment shows that the total pressure of the gases in equilibrium with the solid is 0.116 atm. What is the equilibrium constant Kp and Kc?
An equilibrium mixture of SO2,O2 and SO3 gases at 1500k is determined to consist of 0.244 mol/L SO2, 0.172 mol/L O2 and 0.56 mol/L SO3.
what is the molecular mass nonionic solutes of 8.02 grams of solute in 861 grams of water lower the freezing point to -0.430 c.
What is the pH of a solution that results from diluting 0.30 mol acetic acid (CH3CO2H) and 0.20 mol sodium acetate (NaCH3CO2) with water to a volume of 1.0 L?
An ice cube of 15.1 grams is placed into 304 grams of H 2 O. compute the change in temperature in the H 2 O upon completing melting of the ice.
how many liters of H2 would be formed at 530 mm Hg and 15 degrees celcius if 20.5g of zinc was allowed to react?
a sample of 0.600 moles of metal M reacts completely with excess of flourine to form 46.8g of MF2. How many moles of F are present in sample of MF2 that forms?
If aqueous acetone (80% acetone, 20% h2o) is used as the extraction solvent instead of 100% acetone, the extraction yields of chlorophyll a and beta carotene
When blood is donated, sodium oxalate solution is used to precipitate Ca2+, which triggers clotting. A 108mL sample of blood contains 9.7*10^-5g Ca2+/mL
Calculate the mole percent composition of the mixture. Assume that the response of the detector (area per mole) is the same for each component.
Suppose that the solvent ethanol could serve to replace the methanol in this process, but at the expense of double the concentrations of the solvent in the atmosphere.
The other criterion is very basic and relates to whether simple or fractional is selected
