Today in the review session, they said that when in the same row, charge becomes the determinant of which one is greater.

Kguox1B

Wow, you guys are amazing for putting it on here step by step! This will most definitely be a useful tool, thank you!

So if unless told/shown that it is negative, it will always be Ferrum?

Kguox1B

No, we won't.

Kguox1B

Thanks for all the replies!

I might have missed this in lecture, but will we be expected to come up with a chemical formula based on the element's name?

Kguox1B

Based on the final review session pdf, I understood that the final will be completely composed of homework problems. Is this correct?

Kguox1B

Thanks !

Since we know that shape changing in σ-bonds is possible due to the rotations, will we need to know how many rotations occurred?

Kguox1B

Thank you for this thread

Kguox1B

Thanks for the differentiation !

Kguox1B

Thanks for this response!

Kguox1B

Thank you so much for the examples and the detail in your answer. Makes so much more sense now, I appreciate it!

Which M3 ions (where M is a metal) are predicted to have the following ground-state electron configurations: (a) [Ar]3d6 (b) [Ar]3d5
Can someone explain why a is Co3+ and b is Fe3+?

Kguox1B

I would say number of valence electrons because then we have figure out how to distribute them, which gives us our formal charge.

Kguox1B

Thank you for replying! It makes sense now!

When going over the photoelectric effect, we were given two equations: E=hv-work and 1/2mv^2=hv-work. How do we know which one to use for certain problems? Based on the examples I have seen, I understand how to do it but not why we use a certain equation for a certain part?

Kguox1B

It is towards the end of the textbook. You need to skip the section that says answers and go to "Odd-Numbered Exercises." It starts on page C10.

Kguox1B

I think he said he was just going over it because everyone asks questions about it on here, but that it won't be needed.

Kguox1B

Thank you!

After learning about acetylene, your roommate becomes excited about 4th of July festivities. She assembles a closed vessel containing 190g of acetylene gas and 230g of molecular oxygen, which she plans to ignite in celebration. Identify the limiting reactant for this combustion reaction, and calcula...

Does anyone mind taking pictures of today’s slides or emailing me their notes? I would really appreciate it. My email is kimberlyguox827@gmail.com. Thank you so much.

Kguox1B

Thank you!

Kguox1B

What about for (aq) examples?

Kguox1B

Thank you for relating both equations step by step, my brain appreciates it!

Kguox1B

This might be redundant, but if there are four subparts (a,b,c,d) for one problem, it still only counts for the credit of one problem right? It is not as if I did four different ones?

Kguox1B

Are there any updates on whether AAP has a PLF holding sessions for the class? Online, there are no times available.

Kguox1B

Thank you for the clarification!

In class, we saw an example where the number "100." had 3 significant figures. Does the fact that there is a decimal point after change the sig fig in any way?
