Half a bottle of scotch whiskey is consumed and returned to the cabinet uncorked. Initially the scotch contained 400 grams of ethanol. The unsealed bottle loses ethanol at rate of 0.5grams per day. After sitting in the cabinet over the summer (90 days) with the cork removed, how much alcohol remains in the scotch?
Homework Answers
Initial amount of alcohol = 400g
Amount of alcohol after consumption = 400/2 = 200g
Amount of alcohol lost = 0.5 * 90 = 45 g
Amount of alcohol remaining = 200-45 = 155g

Exercise 5: I was changing 34 around too much that I just made it a separate exercise. Suppose 310. grams of ethanol (ethyl alcohol) is in an aluminum cup of 90.0 grams. Both of these are at 30.0C. A mass m of ice at - 8.5C is taken from a freezer and added to the alcohol in the cup. The final temperature of all the components is 18.0C. Assuming no heat was lost from the system, calculate the mass m...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
