Re: Midterm question 2A

Since the change in volume is zero, w=-P*deltaV is zero. q=-w and deltaH=q/T therefore they are all zero.

Re: Quiz 3

Quiz 3 will cover the Arrhenius equation, naming, constitutional isomers, energy profiles, and Sn2 mechanisms.

Re: Quiz 2 Winter 2017

From the quiz 2 preparation in the course reader, it seems that it will just cover kinetics.

Re: Post All Chemistry Jokes Here

A chemistry teacher was berating the students for not learning the period table of elements. She said "Why when I was your age I knew both their names and weights." One kid popped up, "Yeah, but teacher, there were so few of them back then."

Re: Topics and Formulas on the Quiz

All formulas that you will need relating to the topics we have discussed will be given to you. It's similar to the back of the periodic table of elements you got with your course reader. And no, I do not believe you will be tested on that.

Re: Ch 8 Exercise 107

First covert ounces to grams using the conversion factor 1oz=28.35g. Then calculate the amount of energy released from the cheese by multiplying the specific enthalpy of combustion by the amount of grams. Lastly, multiply the amount of energy by 1min/30kJ to get the required time of exercise. Hope t...

Re: Chapter 8 Question #3 (The First Law)

a) I would start with the equation w=-Pex*ΔV, where P is given as 2.00 atm. Then substitute ΔV for -A*d. The radius of the pump is 3.0cm/2=1.5cm and the pump is depressed 20.o cm thus, d=20.0cm. Plug these values into the equation ΔV=-A*d and the answer into liters. Once you get ΔV plug it into the ...
