Answer:
The answer is hydrogen gas and oxygen gas
Explanation:
When the solubility is the amount of solute that dissolved in a unit volume of the solvent.
and when the balanced reaction equation is:
so, by using the ICE table:
Cd(OH)2(s) ↔ Cd2+ + 2OH-
initial 0 0
change +X +2X
Equ X 2X
so the Ksp expression = [Cd2+] [OH-]^2
and we have Ksp = 7.2 x 10^-15
and when we assume the solubility = X
by substitution:
7.2 x 10^-15 = (X) (2X)^2
7.2 x 10^-15 = X*4X^2
7.2 x 10^-15 = 4X^3
∴X = ∛(7.2x10^-15)/4
= 1.22 x 10^-5 M
∴ the solubility = X = 1.22 x 10^-5 M
Well I'm thinking that it would be both.
The answer is B red blood cells. The other three are part of our immune system to defense for infectious disease. While red blood cells are responsible for transport oxygen from lung to other place in our body.
