Answer:
Ksp = 1.07x10⁻²¹
Explanation:
Molar solubility is defined as moles of solute can be dissolved in 1L.
Ksp for NiS is defined as:
NiS(s) ⇄ Ni²⁺(aq) + S²⁻(aq)
Ksp = [Ni²⁺] [S²⁻]
As molar solubility is 3.27x10⁻¹¹M, concentration of [Ni²⁺] and [S²⁻] is 3.27x10⁻¹¹M for both.
Replacing:
Ksp = [3.27x10⁻¹¹M] [3.27x10⁻¹¹M]
<em>Ksp = 1.07x10⁻²¹</em>

Answer :
Option D) 2.50 X 
Mol/(L s)
Explanation: While calculating the average reaction rate for the given reaction in terms of Cl;
.
using the rate equation which is;
![\frac{delta [Cl]}{delta t}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bdelta%20%5BCl%5D%7D%7Bdelta%20t%7D%20)
=
=
2.50 X Mol/(L s)
Sodium is Highly reactive. It reacts with like everything
In covalent bonding electrons are shared betweed adjacent atoms.
This kind of bonding means that none of the atoms are detached from its electrons.
A molecule of compound is formed when two or more atoms are bonded through covalent bonds. The electrons shared are considered part of the valence electrons (outer energy level) of both atoms forming the covalent bonding.
