(I) A nonvolatile solute is dissolved in pentane and then the volume of this solvent is reduced from 200 mL to 50 mL by evaporation. What is the sign of the entropy change, ??delta??Ssys, for the nonvolatile solute during the evaporation?
a) ??delta??Ssolute < 0 because reducing the volume of solvent decreases the positional disorder of the solute.
b) ??delta?? Ssolute < 0 because reducing the volume of solvent increases the positional disorder of the solute.
c) ??delta?? Ssolute > 0 because reducing the volume of solvent decreases the positional disorder of the solute.
d) ??delta?? Ssolute > 0 because reducing the volume of solvent increases the positional disorder of the solute.
(II) The temperature of 2.00 mol Ne(g) is increased from 25 °C to 200 °C at constant pressure. Calculate the change in the entropy of neon (assume ideal behavior).
(III) Calculate the change in molar entropy when the pressure of argon is allowed to double isothermally (assume ideal behavior).

Standardization of Na2S2O3, Added 0.12 g KIO3 and dissolved in 75 mL of distilled water. Added .20 g of KI to solution, then added 10 mL of 1M HCl and immediately titrated with thiosulfate solution (made by weighed 25 g of Na2S2O3-5H20
How much heat is required to warm 223 g of ice from -44.3°C to 0.0°C, melt the ice, warm the water from 0.0°C to 100.0°C, boil the water, and heat the steam to 173.0°C?
The enthalpy of fusion of water that is the heat required to melt ice is 6.007 kJ/mol. The density of the water is 1.0 g/mL. Presume the specific heat capacity of water is constant and equal to 4.184 J/g/K.
Can someone explain to me what is metastability, what does it mean. If you could, can it also be explained in terms of geology
