Re: Winter 2021 Classes

12 units is the minimum for a full time student and 19 units is the maximum unless you have an exception so you can have more units (-:

Re: Hydrogen bonds

Hydrogen and Carbon's electronegativities are too similar to create the polarity needed for Hydrogen bonds to form.

I like to move out of my room to study to seperate "work space" from resting space. It forces me to pay better attention!

Re: Section 1D #25

the n=2 level would need to have 5 orbitals for 2d to exist, which is impossible as the only l values possible are 0 and 1. Therefore the largest ml range is -1 to +1 and the largest possible number of subshells at n=2 is 3. Hope that helps!

Pretty sure Schrodinger's Wave Function is just used as a way to better understand and conceptualize atomic orbitals.

Re: Understanding Black Body Radiation

Black Body radiation is a theoretical concept, because no such object actually exists with these properties. However, in theory a black body is able to absorb any frequency of light and emit radiation at any wavelength. Any emission is called black body radiation.

Re: Multiplying versus adding

Yup you got it!
As was said above, For addition and subtraction, round to the least amount of decimal places, and when you're multiplying or dividing use the same number of sig figs as the number with the least.
