Exam 3 Material
Homework Page Without Visible Answers
This page has all of the required homework for the material covered in the third exam of the first semester of General Chemistry. The textbook associated with this homework is CHEMISTRY The Central Science by Brown, LeMay, et.al. The last edition I required students to buy was the 12th edition (CHEMISTRY The Central Science, 12th ed. by Brown, LeMay, Bursten, Murphy and Woodward), but any edition of this text will do for this course.
Note: You are expected to go to the end of chapter problems in your textbook, find similar questions, and work out those problems as well. This is just the required list of problems for quiz purposes. You should also study the Exercises within the chapters. The exercises are worked out examples of the questions at the back of the chapter. The study guide also has worked out examples.
These are bare-bones questions. The textbook questions will have additional information that may be useful and that connects the problems to real life applications, many of them in biology.
Thermochemistry (Ch. 5)
Answer the following thermochemistry questions.
What is the first law of thermodynamics?
Answer
Energy can not be created or destroyed, it can change form, but the total amount of energy in the universe remains constant. Energy is conserved.
What is a state function?
Answer
The magnitudes of state functions are independent of the path. Any property of a system, like temperature, where the value of that property doesn't depend on how it got there is a state function.
