No but i am glad i havent
Answer:
2.5 atm
Explanation:
P2 = 1.2 atm x 2.65 L x 345 K / 1.5 L x 298 K
Esto debería ser igual...
2.45 atm (personajes importantes)
<span>Ksp = 1.2 x 10^-17 = [Zn2+] [OH-]^2
Zn(OH)2 <----> Zn2+ + 2OH-
[Zn2+] = x
[OH-] = 2x
1.2 x 10^-17 = (x) ( 2x)^2 = 4 x ^3
x = 1.4 x 10^-6 M
2x = 2.8 x 10^-6 M
pOH = - log 2.8 x 10^-6 = 5.5
pH = 14 - 5.5 =8.5
i think this is it
