<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

Answer: A when going down the periodic table your atomic radius will get bigger same if you got to the side. B Moving left to right within a period or upward within a group, the first ionization energy generally increases
Explanation:
The answer to this question is A. Humidity.. because humitity causes steam
Answer: False
Explanation: The kinetic energy of the molecules is the energy possessed by virtue of motion of particles.
Kinetic energy of the particles is directly proportional to the temperature of the gas.
where T= temperature
R= gas constant
Thus if the particles are moving faster that means the kinetic energy is high, the temperature must be higher and the particles must feel hot to touch.
