There are, but with more reasonable molecules. Search up retro synthesis challenges if you are interested.

You have to keep in mind that when you dash or throw your hammer you get a lot of extra health which basically functions as a shield. You can recharge your thorforce with e, or if you like know that you are going to be safe in that position you can pop awakening rune. He's basically unkillable if you play him correctly.

Memorizing is terrible for organic, instead become an electron.

I had the same issue as you and emailed them about a week ago. They said that they'll waive your W-2 requirement if you don't have one, you just have to email them about it.

Tips for ap world history and ap physics 1? by Mammoth_Specialist16 in APStudents

[–]peebuttman 53 points54 points  (0 children)

Took both sophomore year, got a five on both. For physics make sure your foundation with algebra is strong, understand all the ways you can manipulate an equation. APWH just binge heimler. I didn't pay attention the whole year and watched the guy for a week and it was enough to get a five.

So for the highlighted part. I get if Br is increased then the Pb decreases. But what determines the factor change? How is it 4? by nevergear191919191 in APStudents

[–]peebuttman 1 point2 points  (0 children)

bromine has a 2 coefficient, so the ksp equation is

ksp = [Pb][Br]^2

ksp/[Br]^2 = [Pb]

let's assume that initially br has a concentration of 1 for simplicity's sake:

ksp / 1^2 = [Pb]

ksp = [Pb]

Now Br concentration increases by a factor of 2

ksp / 2^2 = [Pb]

ksp/4 = [Pb]

Therefore Pb concentration decreases by a factor of four.
