Based on the given value of the ksp, what is the molar solubility of mg(oh)2 in 0.200 m naoh?
xz_007 [3.2K]
The Ksp refers to the equilibrium constant for a solid dissolving in an aqueous solution.
 Ksp=  5.61×10⁻¹¹  

The equation for this reaction is: 
 Mg(OH)₂ (s) ⇔ Mg²⁺ (aq) + 2 OH⁻ (aq) 

 And the associated equilibrium expression is: 
 Ksp = [Mg2+]  x  [OH–]² 
 Mg(OH)₂ its solid and because of that doesn't have molarity, so its not included.
 
Ksp             = [Mg²⁺]   x   [OH–]²
5.61x10⁻¹¹  = (x) (0.200)² 
x = 1,4025 x 10⁻⁹

C. If the proton number increases while the number of energy levels remains constant,
Vladimir79 [104]

It increases

The attractive force between the nucleus and the electrons INCREASES if the proton number increases while the number of energy levels remains constant.

Explanation:

Remember that protons carry a positive charge while electrons carry a negative charges. Unlike charges attract while like charges repel. An increase in the number of protons increases the positive charge of the atomic nucleus. This means that the force of attraction on the electron cloud of the atom increases.

This is why the atomic radius of atoms decreases across a period (from left to right) as the mass number of the atoms increase (while the number of electron orbitals remains the same across the period).
