Test Prep

While I may not even be there for the test- I'm still studying during the short period of time I have enough energy to. So here's some resources to review all of stoichiometry:

Limiting Reagents and Percent Yield
Explanation + examples
Walk through Video

Also do the worksheets on schoology!

Percent Yield

Last thing we learned in this Unit was percent yield:

Actual Yield / Theoretical Yield x 100 = % Yield

Doing this as another step to Stoichiometry can be a bit confusing. Here's some resources to help:

Lab. So Far

I haven't been here for most of the lab but so far what I've seen is that we're making solid copper in a baby food jar using a nail. Single Replacement reaction: Copper II Chloride + Iron = Iron II Chloride +Copper. On the day I was there we-

Washed off the remainder of the nail
Siphoned off the solution of Iron II Chloride
Washed copper with HCl and distilled water
Put copper in 'drying oven'

Quiz

Oh boy. I feel like that was way harder than it should have been. I've had an easy time learning this yet I didn't do very well on the test. I don't mind making connections between what I've learned and harder questions but to do it on a test with limited time worth a huge amount of points is very nerve wracking. Trying to find a way around this confusion still.

Some study links for people who didn't take it yesterday for some reason:
Stoichiometry 1
2- Video
LOTS of links and resources
