Thanks for this video, Sir. Just realized that I screwed up on a good 2 problems during my AP chem test....

Also, one more question (I am just now coming back to finish watching this video). For question 6 part (c), me being so stressed I somehow interpreted NO2+ as a gaining of an electron, so my Lewis structure for (c) i is ofc wrong, and I had an additional electron on the nitrogen and a double bond on one of the oxygens. Do you think for part (c) ii I would get credit for still agreeing with the student and supporting my answer with my Lewis structure in part (c) i? In (c) ii, I said something along the lines of the fact of an additional electron increases repulsion and decreases the bond angle for NO2+.

I am so embarrassed by completely missing these basic points for Lewis structures…

Do you think an answer of 3.95 would be acceptable for number 1 part c for the ph

For question 2 part (g), do you think a ratio of 9/1 would be accepted?
