This would be a compound because it has more than one molecules that are the same that are attached together forming a chemical bond.
First, we need to get POH value & we can get it from this formula:
PH + POH = 14
when we have PH = 8.59
∴ POH = 14 - 8.59 = 5.41
then, we need to get [OH-] & we can get it using POH:
POH = -㏒[OH]
5.41 = -㏒[OH]
∴ [OH] = 3.89 x 10^-6
when Ksp = [Fe2-][OH-]^2
and when we have Ksp = 4.87 x 10^-17
so, by substitution:
4.87 x 10^-17 = [Fe2-] * (3.89 x 10 ^-6)^2
∴[Fe2-] = 3.22 x 10^-6 M
∴ above 3.22 x 10^-6 M of Fe2+ , Fe(OH)2 will precipitate

<span>A molecule has one carbon-carbon double bond and four monovalent atoms or groups have two isomers.
</span>
<span>When there is different arrangement of atoms in a compound
but having the save molecular formula, these are called isomers of that
compound. These isomers also have different properties due to the change of arrangement
of atoms or different structure.</span>
True. Each contour line on a topographic map represent a certain elevation; the closer they are, the steeper the surface is. All points on a contour line are the same elevation.
