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?

Expert Solution

Absolute pressure at a point 7.52 cm below the ethyl alcohol-mercury interface

P = Pa + +

= 1.013 * 105 + 789 *9.8*1.36 + 13600*9.8*0.0752

= 121838 .448 Pascals

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. 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 work...
