Chapter 8: Chemical Equations and Reactions

Chapter 8: Chemical Equations and Reactions Study Guide This guide is best followed with the live links from the website at: http://discoverva.com/Chemsite/chemindex09.html You can also get to the website through the School Net.

Numbered items in red, you should DO! Numbered items in black you should UNDERSTAND FULLY. The concepts in this chapter are best understood with graphic illustrations (drawings). Bring questions to class. When answering questions: 1. Write all equations used 2. Match given values to variables, isolate unknowns 3. Show all steps involved 4. Use correct Sig Figs, Units and Sci Notation where indicated 5. Place a “box” around your final answer. A neat and organized presentation is REQUIRED. When this series of assignments is graded, you will have to quickly highlight specific questions and answers. You must be able to quickly “find” the selected questions for grading.

Pay close attention to “Chapter Highlights” page 289. 3. Focus on the VOCABULARY, page 250.

Note: All the videos are directly from the “Online Textbook”. This document is simply an easy way to have all videos in “one place” to view AS YOU READ/STUDY.

TEST QUESTIONS COME FROM HOMEWORK ASSIGNMENTS.

Identify the homework problems you do not understand, bring the list to class and they will be explained.

For the test, you will need to do is understand how the topics and vocabulary relate to the homework questions and recall how you completed each homework question = “A” on the test!!! UTV + HWQ = A

When doubt, CONVERT TO MOLES. If that doesn’t work, ASK!!!
