Hi everyone,

Happy Week 3!

Here is the worksheet for today. Please give your best attempt for this midterm review before coming to session.

See you then! =)

Hey Gabriel!

I was wondering if an answer key would be posted? Thank you!

[Emily Do 1F]

Hi! I was wondering if the worksheet for tomorrow, Sunday January 28, would be the same one that was covered during workshop today (Saturday 1/27)? Thank you!

I will post a key either later today or tomorrow. I am still revising the key. :-)

Yes, it will be more or less the same from yesterday.

By the way, someone left their scientific calculator in the Sycamore room today. I've attached a picture below of where it was left. I'm currently holding onto it, so please reach out if it's yours. My email is viviankha11@ucla.edu.

Here is the key!

Hey Gabriel,

For number 15, why did you divide (0.024*.110)^2 by ((1-0.024)*0.110). Shouldn't the denominator be 0.110-(0.024*0.110). Also, on the key, the M is 0.110, but on the worksheet, it is 0.100M

[Vivian Kha 2J]

For #15, the denominator is correct. The concentration of the reactant is 0.110 - (0.024*0.110) which Gabriel simplified in the key to (1-0.024)*0.110. Additionally, I talked to Gabriel about the M of solution and the original had a typo. It was always supposed to be 0.110 M solution because if you do the calculations with 0.100 M solution, you will get 5.9 * 10^-5 which isn't one of the options.

Would you mind explaining the answer to #13 part c?
