Mercury is poured into a tall glass. Ethyl alcohol (which does not mix with mercury) is then poured on top of the mercury until the height of the ethyl alcohol itself is 113 cm. The air pressure at the top of the ethyl alcohol is one atmosphere. What is the absolute pressure at a point that is 9.27 cm below the ethyl alcohol-mercury interface?

Mercury is poured into a tall glass. Ethyl alcohol (which does
not mix with mercury) is then poured on top of the mercury until
the height of the ethyl alcohol itself is 136 cm. The air pressure
at the top of the ethyl alcohol is one atmosphere. What is the
absolute pressure at a point that is 7.52 cm below the ethyl
alcohol-mercury interface?

An experiment requires 74.2 mL of ethyl alcohol. If the density
of ethyl alcohol is 0.790 g/cm3, what is the mass of 74.2 mL of
ethyl alcohol?

Ethyl alcohol vapors and air are mixed. The partial pressure of
the ethyl alcohol is 0.550 kPa. The pressure and temperature of the
ideal gas mixture are 96.0 kPa and 25.0oC respectively. Calculate
the mol fraction (PPM), the mass concentration (mg/m3) and the
molar concentration (mol/m3) of the ethyl alcohol.

Consider a crystallization of sulfanilamide in which
10ml of hot 95% ethyl alcohol is added to 0.10g of impure
sulfanilamide. After the solid has dissolved, the solution is
cooled to room temperature and then placed in an ice water bath. No
crystals form, even after scratching with a glass rod. explain why
this crystallization failed. What would you have to do at this
point to make the crystallization work??

An organic liquid is a mixture of methyl alcohol (CH3OH) and
ethyl alcohol (C2H5OH). A 0.220-g sample of the liquid is burned in
an excess of O2(g) and yields 0.380 g CO2(g) (carbon dioxide).
Set up two algebraic equations, one expressing the mass of
carbon dioxide produced in terms of each reagent and the other
expressing the mass of sample burned in terms of each reagent.

An organic liquid is a mixture of methyl alcohol (CH3OH) and
ethyl alcohol (C2H5OH). A 0.220-gsample of the liquid is burned in
an excess of O2(g) and yields 0.348 g CO2(g) (carbon dioxide).
Set up two algebraic equations, one expressing the mass of
carbon dioxide produced in terms of each reagent and the other
expressing the mass of sample burned in terms of each reagent.

An organic liquid is a mixture of methyl alcohol (CH3OH) and
ethyl alcohol (C2H5OH). A 0.220-g sample of the liquid is burned in
an excess of O2(g) and yields 0.376 g CO2(g) (carbon dioxide).
Set up two algebraic equations, one expressing the mass of
carbon dioxide produced in terms of each reagent and the other
expressing the mass of sample burned in terms of each reagent. What
is the mass of methyl alcohol (CH3OH) in the sample?

Ice cubes at 0 c are poured into a glass that contains 150 g of
liquid water at 20 c. The contents of the glass are gently stirred
and after short time the ice melts and the liquid cools to 0 c. No
appreciable heat exchange with the environment takes place.
a) calculate the entropy change of the universe (system plus
environment) during the process. Cp=Cv = 4.18 kj/kgK
b)if the same process were performed reversibly, how much useful
