Finals week! I'm very proud of the hard work you've done for this class over the quarter... now show how much you've learned on the finals and be ready for the winter break!

There are three assignments due during finals week. There will be no extensions for late work, so make sure you turn your material in by the posted due date for your lab section. Please be aware: I do not return final exams to students. You will be able to see your final grades online but not your graded assignments, and your final grade in the class will be available by 5 PM Friday. The three assignments are:

• The Lab Final
  • The Lab Final will be a Take Home Lab Final that consists of six "show your work" problems relating to the various labs we have completed this term.
  • Showing your work on these problems is critical! Be clear in your steps, circle final answers, etc.
  • Use your old lab reports to help conquer the questions in the Lab Final. You must complete this assignment on your own with no assistance from lab partners, tutors or friends.
  • The Lab Final will be available by 8 PM Sunday, December 7 via an email link (check your email!) The Lab Final will be due at the time of your Lecture Final (see below).
• The Lecture Final
  • The Lecture Final will cover Chapter One through Chapter Seven Part I (up to section 7.2) and consist of 24 multiple-choice questions and four short answer questions. The questions will range from all six problem sets this quarter (i.e. from sig figs up to types of reactions).
  • The Lecture Final is worth a total of 140 points; 120 of the points will be from the 24 multiple-choice questions and the other 20 points from the short answer questions.
  • A Lecture Final Exam Review is available as a Complete Lecture Video (link).
  • A Sample Final Exam (answers at the end) is available to assist with your studying
• The Net Ionic Reactions Lab
  • The Net Ionic Reactions lab will be due at the time of your Lecture Final (see below.)
