Items Due During Week 11:
All Sections:
- All late work (labs, etc.) is due Friday, December 5 by 9 AM. All extra credit for CH 221 closes Friday at 9 AM as well.
Finals week is right around the corner - ack! - but this also means that the winter break is coming quickly - I guess they even out somehow... ;-)
This week we investigate the empirical formula and its relation to the molecular formula. We will also look at the important concept of molarity with regards to solution concentration. We will learn how to balance chemical equations, and also investigate some common patterns of reactivity which allow chemists to predict the products of a reaction. If you have any questions, let me know!
Here's what is happening in week 11 of CH 221:
- Explore the material in Chapter 6 and Chapter 7.1 - 7.2. There are several tools to help you learn the material.... they include:
- Due: Problem Set #6 which covers problems from Chapter 6 and Chapter 7 (7.1 - 7.2 only.)
- This Week: Seminar Self Quiz #6 and the (actual) Quiz #6
- All quizzes (Seminar Self Quizzes and actual Quizzes, as well as midterm exams and finals) are closed book / no notes allowed. You cannot use a cell phone or computer; you can have a dedicated calculator and a periodic table (which I will provide) only.
- First, take Seminar Self Quiz #6. You will have 20-30 minutes to complete the quiz, and afterwards we will self correct the Quiz as a class before turning it in. If you are late, or do not attend recitation for any reason, your score will be a zero on the Seminar Self Quiz.
- After taking the Seminar Self Quiz, you will take the actual Quiz #6. Quiz #6 will take about 30 minutes and consist of several 'show your work' questions. Turn in the quiz when done (I will pass back any corrected work I have for you at this time.)
- Sample Quiz #6 (answers at the end) might be useful to help you prepare and study.
- Start: The Net Ionic Reactions Lab.
- Bring a printed copy of the Net Ionic Reactions lab with you to class.
- Here is a video which shows what the lab will be like, offer hints, etc.
- This lab will be due at the time of your Lecture Final during finals week.
- All extra credit closes Friday, December 5 at 9 AM.
Here's a preview of what's going to be happening during Week #12 - Finals Week:
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
