About SI for this Course
Whether general chemisty is like a second language to you or not, SI is a great way to knock out some out-of-class study time - the recommended amount for any class is 3 hours per credit hour each week. My sessions will include mostly worksheets, a majority of which will be posted here before each session and are to be completed in session on both an individual and group basis. I will also try to incorporate other fun activities that will provide lots of practice of the concepts discussed in lecture. The answer keys (without solutions) to the posted worksheets will be made available the day I post exam reviews so if you'd like answers earlier, please attend SI. Feel free to contact me through the SI website to address any additonal questions or concerns!
My response to a student that may help others:
"The more negative the standard E red value is for a substance, the better a reducing agent it is (meaning that it leans a little more towards being oxidized), and the worse an oxidizing agent it is (meaning that it leans a little farther from being reduced). Remember that a reducing agent means the species that's oxidized in a redox reaction, and an oxidizing agent is the species that's reduced (opposite of what one would originally assume). So in a redox reaction, the species being oxidized would have the lower E red number and the species being reduced would have the higher E red number.
The above rule has to do with voltaic cells and spontaneous reactions. It does not apply when it comes to electrolysis/electrolytic cells because these deal with nonspontaneous reactions and require energy to complete. Basically yes, an electrolysis process is the opposite of everything stated above."
Today's agenda is a worksheet and the rest of the week will consist of the same and/or a learning acitivity. Just a heads up that Wednesday's (11/1) worksheet/ativity will not be posted but SI will still be happening that day. So whenever a worksheet isn't posted for a session, it means that in-session is the only place it'll be available, not that that day's session has been cancelled. Cancelled sessions will be announced and typically only occur the session after an exam.
Hey guys! So I have a couple of announcements.
1) I was a bit frazzled in today’s session (sorry about that) and for some reason, let y’all out a few minutes early because I thought our time was up. For anyone who was confused about that, SI ends at 4 pm on Sundays and 5 pm on Mondays and Wednesdays!
2) For the person who asked me about question 1c on the homework, a hint is to find Experiment 2’s rate of formation for Br2 and then relate this back to the rate of consumption for Br- by its stoichiometry/relative rates equation. Refer back to the slides for Lecture 2. Hope this helps and apologies for not having a clear answer at the session! I needed time to look over the problem first.
3) In terms of homework this semester, please utilize professor/TA office hours and the Chemistry Help Center in Gilman 1761 for further assistance! SI leaders try to steer clear of any class assignments in order to encourage students to take advantage of other resources.
