It's a cool guys face. He has sun glasses on. (h) means hot
triple h msn
(H)
5k - 2*(h - 8k) = 5k - 2h + 16k = 21k - 2h
the formula is c2h4 like a normal ethane, however it has the square brackets around it with the 'n' on the bottom right to show that it is polymer. H H l l -C- C- (with the square brackets) l l H H n
For a weak acid, HA...HA ==> H^+ + A^- Ka = [H+][A-]/[HA] Plug these values into the Ka equation. You also must know the [HA] that you start with. Solve for [H+] Take -log [H+] = pH
2k - 3(h - 5k) = 2k - 3h + 15k = 17k - 3h
Yep, normally should be on the R/H side at the back, attached the the exhaust studs, and one on the l/h side at the front!
What does 14 K and H with a circle in it mean
h= hour
H mean is halal M mean is muslim
h h h
The pH tells you the concentration of H+ ions in the solution according to this formula pH = -log [H+] (where the square brackets mean "the concentration of" whatever is inside the brackets) So, if you have the pH, you can find the concentration of H+ from this: [H+] = 10-pH If the pH is 5.00, then 10-5 = 1 x 10-5 M = 0.00001 moles per liter But that's [H+], not the concentration of [OH-]! But those two are related like this: [H+] * [OH-] = 10-14. So to find [OH-], we use: [OH-] = 10-14 / [H+] In this case, [OH-] = 1 x 10-9 M
