The answer is Na < Cl
Chlorine is more electronegative than sodium because this follows the trend of the periodic table. The trend states that an element's electronegativity increases from left to right of a period and bottom to up of a group. Since sodium and chlorine are from the same period, and chlorine is at the right of sodium, chlorine is more electronegative.
-When Ksp is the solubility product constant for a solid substance when it
dissolved in an aqueous solution, and measure the level at which a solute
dissolves in the solution.
- and we have the solubility and it is the maximum quantity of solute which can dissolve in a certain solute
we can assume the solubility = X = 2.2 x 10^-5 M
and when the balanced reaction equation is:
Mn(OH)2(s) ↔ Mn2+ + 2OH-
∴ the Ksp expression is = [Mn2+] [OH-]^2
when [Mn2+] = X = 2.2 x 10^-5 M
and [OH-] = 2X = 2*(2.2 x 10^-5) = 4.4 x 10^-5 M
by substitution:
∴ Ksp = X * (2X)^2
= (2.2 x 10^-5)(4.4 x 10^-5)^2
= 4.3 x 10^-14
The density of mercury is 13.6 g/mL. Hope this helps you solve.
It’s the doubles I think not sure let me know if it’s true
