honestly I would just toss a couple inside the beaker and shake it around. The shaking would represent ambient temp and if you do it right it should “crystallize” into its lowest energy state, at least in theory 😂

5:11 - clarification: 73mL - 57mL gave me the volume of the my 4 spheres (2 black and 2 white). I multiplied by 16 to get the total volume of all the spheres in my beaker (the volume of 4 spheres * 16 = volume of 64 spheres). The "96" and "160" is my showing my work when I multiple 16 * 16 because I didn't have a calculator and I couldn't use the calculator on my phone because I was recording with my phone. The point is - multiple 16 mL (volume of 4 spheres) by 16 to get the volume of all 63 spheres = 256 mL. Let me know if you have any other questions.

5:57 correction - silvers going to end in 4d⁹ and gold is going to end in 5d⁹. Actually copper, silver, and gold are all exceptions to aufbau...so they are all going to have full d-orbitals at the expense of their final s-orbital.

Why do i get 4.54230*10^-4 otherwise very good thanks

Hertz = cycles per second = one divided by seconds = 1/sec

kinda outdated imo, wheres flashy editing?

3:17 Correction: In hotel C, there is another pair of electrons spinning in the same direction in one of the 3p orbitals. That is also a violation. 8:41 Correction: ml should be +1 direction (not +2) 9:21 Correction: ...that "room" (not hotel) is facing the parking lot....this "room" is facing the beach... 10:22 Correction: The circled electron in hotel B is in the 3d orbital (not 4d). n= 3 (not n=4).

👍🏻

0:25 - should be "atomic number" not "atomic mass"

Nice videos, Really helpful! Keep up the good work🔥

thank you <3

answer should be in units of μm (micrometers)

a. is 2.6 m² (not 2.5 m²)

final answer should have units of cubic meters (m³)

Correction @0:45 - I meant to say "melting point" (not "boiling point")

Correction @5:30 moving the decimal to the left 3 times is the same thing as dividing by 1,000 (not 100). 1kJ =1,000 J

I copied the mass incorrectly. Mass should be 96.1g. Final answer should be 44.4g/mol.

Distiller all the way. It’s the easiest and best quality. I use the cheapest one and it still puts out 0-1ppm. I use a 4hr timer with mine. This way there is always a tiny bit at the bottom when done. I can go a month or two with every day use before cleaning

soak the filter for a day better yet toss it in the garbage and go with your distiller

@26:18 denominator should read (0.01M²) (0.1M) i.e. - if you square (0.1M)², you get → 0.01M²

@3:55 the last conversion factor in green should be PH₃, not PH₄. Good catch Carlton!

Very helpful. Thanks a lot

at 14:10 molar mass of nitrogen x 2 is 28g/mol, not 48g/mol. Final answer should be 8.80 mol.
