Practice Problems with Lewis Structures
มุมมอง 2265 หลายเดือนก่อน
A walkthrough of some practice problems that cover the following learning objectives: 1) Draw Lewis dot structures for atoms, ions, ionic compounds, and covalent compounds 2) Classify bonds as covalent, polar covalent, or ionic 3) Apply the octet rule to Lewis structures of compounds and ions 4) Recognize covalent compounds that do not follow the octet rule due to incomplete octet, odd number o...
Limiting Reagent Practice Problem

You forgot to remove the 2 bottom dots on Bromine at 4:40
I just double checked, and the structure at 4:40 is the correct one. If we removed those two dots, our structure would not have the correct electron count. Hope that helps!
@@drvv4739 oh ok, thanks for the clarification ☺️
Thanks, this was so helpful!
Can you help me with this question pls? Select the Lewis structure in which formal charges are minimized for the periodate anion, IO4 - . (A) I with 4 single bonds to O (B) I with 3 single and 1 double bond to O (C) I with 2 single and 2 double bonds to O (D) I with 1 single and 3 double bonds to O (E) I with 4 double bonds to O
sure
@@noblevenom2858 No worried any more, I passed my Chem test. Now I can forget about this hell of a brainrot sub
This was really so helpful thank you Soo much ✨
