Recommend Problems for Chapter 12 Problems for Oxtoby: Chapter 12: 1-4, 9, 31-36, 67, 72 (Oxtoby is much more calculation-focused than we are; these are intended to help you understand the  various aspects of gases and not generally representative of exam questions.) Additional Problems: From the following pairs, pick the one that would represent higher kinetic energy: A) A reaction that glows red or  a reaction that glows blue – blue represents the release of light at a  higher energy than red B)  1 kg weight travelling at 2 m/s  or a 2kg weight travelling at 1m/s –  Velocity is squared in the  equation and so would have a greater effect than mass C) A 1kg weight suspended at 2 meters in the air or a 2kg weight suspended at 1 meter in the air-  Neither both are examples of potential energy From the following pairs, pick the one with the higher potential energy: A) O 2  or  2O – Atomic orbitals have higher potential energy than molecular orbitals B) OH -  or  O 2-  and H

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
