Instructions
This lab is based on the Lab Manual. The Lab report is in a quiz format. No template is required.
If you DO NOT want to Fail this lab, please DO NOT START it by doing the Lab Report. Instead, follow the instructions below and enjoy your success! Click here to open the link How_to_Conduct LabReport_Based_Labs (https://fsw.instructure.com/courses/1124909/files/85820291/download?wrap=1) and follow all steps applicable to this lab activity. Download the Lab Manual in Word. (https://fsw.instructure.com/courses/1124909/files/86440167?wrap=1) If your computer distorts the lab format, download the Lab Manual in pdf (https://fsw.instructure.com/courses/1124909/files/86440168?wrap=1) (https://fsw.instructure.com/courses/1124909/files/86440168?wrap=1) format. Explore each section of the Introduction , try Examples , and then Practice Problems. Check out the answers and refer to Helpful Links and References in the Manual and Video Tutorials in the Canvas Module if you need help. Go to the General and Group discussion forums and ASK (if you need) or OFFER (if you feel you can) help in this area. Make sure you feel comfortable with every section because you will get similar problems in the Lab Report. Use your posts to get grades for the Graded discussion. When you feel prepared, complete the Lab Report. It is in the form of a quiz. You do not need to use any simulations and templates in this lab. To insert the picture of your work in the Lab Report, you have to take a picture of your calculations that must be done according to the examples, save it on your computer in the common format , and then insert the picture in the corresponding text box. Requirements You have 3 attempts for this assignment to help you master your skills in applying simple algebra to solve problems in chemistry. The assignment is not timed, so DO NOT guess. It will not help you in the future. Rather, take some time between attempts to study the topics where you did not feel confident. Good Luck! Need Help?
