Im stuck on this problem too and I'm not really understanding the concept. Would it be better to draw the lewis structure or label which of the atoms is more electronegative

Re: How to relax

I usually go on tik tok to give me a boost of serotonin or I listen to music that is perfect for laying on the group and starring at the ceiling. You can also try baking or napping.

There isn't a restriction on calculators so you're welcome to use any (recommend: a scientific one) and the professors website provides a periodic table. Hope this was helpful !

Re: Spectral Lines

Spectral lines are essentially lines that denote how much energy is emitted or absorbed from the light source. Using these lines, we can determine atoms or molecules; hence, they play a key role in spectroscopy. The range of their emission or absorption allows us to match what atom or molecule also...

Re: Sapling Week 1 #8

I was stuck on this problem for a while too! At first, I thought the double bonds had a bigger meaning for this problem but they didn't. I counted the elements (from the picture) for the molecular formula and later calculated the molar mass.
