Notices:

N.B. In order to take Chem 102 , students must be registered in both a lecture section and a lab section in the same term.

Laboratory credit may be allowed for students who have successfully completed the laboratory within the past three years. Credit is provided for only one subsequent attempt. Students applying for laboratory credit from previous years must email the First Year Senior Lab Instructor, Monica Reimer and request laboratory credit from the previous year. In the e-mail , please include your student number and a previous one, if you had one before the present system, the term that you took the course, the number of the course and your full name as it is on your registration.

If past lab credit is denied, the student must immediately register in a lab section.

Labs begin the week of January 9, 2012.

Drop-in opens January 11, 2012.

Any report not in the appropriate report slot (in the hallway on 2nd floor, Elliott Building) when due will lose 25% off the maximum mark possible for the report.

No reports that are due will be accepted after 4:00 p.m. on the sixth day following the laboratory period in which the experiment was carried out. (However, for experiments done on Monday, the time is 8:30 a.m. the Monday following.)

Student Evaluation

Student performance is assessed continuously on the basis of: pre-lab quizzes, results, assignments and reports, quality of personal and technical performance in the laboratory, notebook keeping and laboratory reports.

A passing mark (50%) must be attained in the laboratory and 70% of the experiments must be completed and graded.

The laboratory component will contribute 33% to the course mark.

 

Expt. 1. Click here for the equation to calculate Rf values.

 

Expt. 2.

Equation for the comparison between the experimenal value and the predicted value for the moles of hydrogen gas.
