Note from lab this week.  I forgot to emphasize that the Thu lab people should work Q's 9.68 (in current text) and 9.112 before leaving lab.  

We did on Wed and the discussions were helpful.  9.68 is an assigned  HW Q.  People that actually work it and check their answer usually always ask.

Q 9.112 is one of the best summary enthalpy questions in Ch 9.

Second class survey (worth another 1% of grade if completed on time)
Very sorry for this short turn around, but I only received the link and information today.  Please be prompt in completing it before the requested Oct 27 deadline.

This survey consists of twelve questions about supplemental instruction, eight general confidence questions, and eighteen chemistry content questions with a follow up question about your confidence answering the content question. The confidence and content questions span knowledge gained in College Chemistry I through Organic Chemistry II. You, therefore, are not expected to get a question correct over a topic in a course that you haven't taken, just do your best.

The last screen of the survey is a Thank You note. You MUST click submit on that screen for your response to be recorded.
Once you click submit on the Thank You note screen, a certificate of completion will be sent to your email.

This survey is available from October 13-27, 2023. Your professor will receive an email on November 1st indicating who responded to the survey.

---------------------------------------
Lab grading notes:
Some will receive back their Separations lab with things like "-2 Tech" or "-4 Tech" point deductions.  This reflects the fact that we gave you a window to hit the right answer, the correct %(w/w) sand and salt.  Results outside this window were hit with a point deduction.  Each %(w/w) was worth 2 technique points; it was possible to get one right but have an error in the other.

Postlab Q's.  People are giving vague answers like "changed the mass" or "affected the mass" or "my results would be off."  You have to commit.  Did this increase or decrease the mass as a result of that error.

Some will see lots of points removed in their density lab for significant figures using different pieces of equipment.  This is a discipline in lab issue.  You have to be mindful of how many SF each piece of equipment allows all the time and make readings accordingly.

Volunteers sought for anxiety study
My name is Cynthia Price, and I am currently a graduate student at the University of Central Arkansas (UCA) School of Nursing. I would like to invite you to participate in my educational research project. I am looking for first-year college students, ages 18-25, who self-identify with anxiety. Many first-year college students have self-identified with anxiety.

The purpose of my project is to determine if using a biofeedback application affects anxiety in first-year college students who self-identify with anxiety. Participants will be asked to participate in a two-month study. Total participation will take approximately 5.15 to 7.5 hours.

Please see the attached flyer for more details. Please contact Cynthia Price at email (cprice14@cub.uca.edu) or phone (937-689-1932) if you are interested in participating.    Promotional flyer posted here.

Provided for you:

Avogadro's number

If you don't see something here, it probably means I will not provide it.  Please feel free to ask if you are unsure.
---------------------------------------

Wed Sep 13, Thu Sep 14  LAB = working problems for Fri's exam
Comments re. measurements lab, things to fix in the future:
>Sig figs were where people lost lots of points.  Typically the numbers reported did not reflect the precision available for the equipment used.
>Too many failed to submit prelabs as PRElabs.  These are due 1st thing when you come to class.
>Recall that ALL day we were trying to measure volumes of 25 mL.  Inexplicably, some reported volumes of 75 mL of 55 mL.  This is a case of paying no attention to what you are trying to measure.  Some consideration would have convinced people that such values could not possibly be right!  Most of these forgot to subtract the mass of empty beakers.
>Some of the reflection questions were vague and ambivalent.  People said their measurements were "off" (what does that mean).  How would you feel if you surgeon said they might have been "off" in excising your brain tumor?  Some said "we should have been more careful using _______."  It is a given that you are being careful.  A given.  How would you feel if your pharmacist said they should have been "more careful" measuring your drug dosages.  Be thoughtful about your sources of error and whether they would lead to results that are too high or too low.
> Finally, some chose the grad cyl for the final drug lab Q.  The grad cyl lacks the precision (+/- 0.1 mL) to make the meausrements ask for (out to +/- 0.01).  If the result was the difference between life in prison or complete exoneration, you'd demand that kind of precision and would not settle for a grad cylinder.

UCA See something, Say Something campaign
We have a collective responsibility to look out for each other.
UCA's CARE Team allows us to care for and support each other on this sprawling busy campus. Concerned professors and classmates can report concerns to the CARE Team office using the Student of Concern Report. There is a guide on their website to help determine the best course of action when reporting. If you feel someone is in immediate danger or if someone is experiencing a medical emergency, please call 911.   Together we can all work toward a successful fall semester.

Start of term survey:  worth 1% of your overall course grade if completed on time (by Sep 10)

This survey consists of four questions about you, eight general confidence questions, and eighteen chemistry content questions with a follow up question about your confidence answering the content question. The confidence and content questions span knowledge gained in College Chemistry I through Organic Chemistry II. You are not expected to get a question correct over a topic in a course that you haven't taken; just do your best.

The last screen of the survey is a Thank You note. You MUST click submit on that screen for your response to be recorded. Once you click submit on the Thank You note screen, a certificate of completion will be sent to your email.
This survey is available from August 24, 2023 to September 10, 2023. Your professor will receive an email on September 13th indicating who responded to the survey.     Link to survey:   https://forms.gle/fKG5PRGJj1RgqxRt8
