Today you took your test! Homework is to do this tutorial on precipitation reactions. Take notes (with pictures!!) and submit your tutorial results to my e-mail: marguerite dot wiseman at apsva.us (but put a . in for dot and an @ for at) Reaction Videos here show some examples of precipitation reactions.
Today I handed out a challenge stoichiometry problem that involved 3 sequential reactions…after going over how to do that you all continued to work on the packet problems including the textbook problems. So for tomorrow you must have the following complete: All of page 1 75% of page 4 75% of page 5 All of […]
Agenda 1. Review solutions 2. Make your 0.5 M (or whatever most concentrated solution) 3. Set-up lab notebook w/ appropriate data tables a) Data for making each level of IV b) Data you will take for each reaction c) Results (i.e. actual yield, theoretical yield, percent yield) 4. Calculate theoretical yields for each […]
Agenda: Pop quiz on limiting reactant and dilutions? Tutorial: Dilutions, Submit completion to me via e-mail: marguerite dot wiseman @ apsva.us Tutorial: Limiting Reactant, Submit completion to me via e-mail: marguerite dot wiseman @ apsva.us Comments on labs Uncertainty on balance Use of uncertainties for calculated values “Commenting on results” what it means and using […]
Today I handed back the test and let you know that retakes for naming and formulas would be on Wednesday during 8:20 or H block. If you intend to retake you need to come to a review session on Monday after school or you need to provide some evidence that you are actually going to […]
Today you had time to finish up your Mole ratios lab, work on naming acids, review solutions calculations (packet) and begin reviewing stoichiometry (packet).
Today we did a little smart board lesson on conservation of mass and the idea of mole ratios. You guys were supposed to balance reactions and draw pictures at the molecular level so that I could see that you understood what the coefficents meant, etc. Then we completed the mole ratios lab. Homework was […]
Today we started with notes on the smart board (here’s a pdf copy). We went over dissociation of ionic compounds and you did a piece of this activity. Homework is to do page 1 in giant worksheet packet (although doing page 4 would also be good since we did enough in class for you to […]
Today we started with a practice naming quiz. When I went over the answers I also reviewed some naming rules and patterns Next we prepared for lab – set up lab notebook, did pre-lab problems, etc. We only had about 40 minutes to do the lab and there was so much difficulty in getting equipment […]
Today we spent the short class completing the empirical formula virtual lab you started last class. I also handed out the lab for next class (Analysis of Alum) and a worksheet to help you with vocab on hydrates. Homework: Finish virtual empirical formula lab, read alum lab, you may also need to read the page […]
