Homework: Due Monday, 11.28.16

Read chapeter 17.1 – 17.3

Complete the practice test. I know there are items on the practice test we haven’t gone over yet, you an try them but I will not hold you accountable for them.

Happy Thanksgiving!

If you don’t have the instructions for the analysis for the Stoichiometry Lab (2nd period), here they are. It is due on Monday, 11.28.

Analysis – You need to show all your work to get credit!!!
1. Find the actual yield of silver: Subtract the mass of the empty beaker from the mass of the beaker + silver crystals.
2. Find the theoretical yield of silver, this is a limiting reactant problem:
a. Find the mass of Cu that reacted by subtracting the (mass of the copper after the reaction) from the( mass of the copper) before the reaction.
b. Using that answer from 2a as your given, complete all 3 parts of a stoichiometry problem to determine the mass of silver theoretically produced from that copper.
c. Find the mass of AgNO3 that reacted by subtracting the (mass of the empty vial) from the (mass of the vial + AgNO3).
d. Using that answer from 2c as your given, complete all 3 parts of a stoichiometry problem to determine the mass of silver theoretically produced from the AgNO3.
e. Which answer is smaller, your answer from 2b or your answer from 2d? Whichever answer is smaller is your theoretical yield!
f. Find the % yield = (actual yield/theoretical yield) x 100.
