The ground state ion that has unpaired electrons is <u>Sc²⁺ ion</u>; option C is correct.
<h3>
What is ground state ion?</h3>
The ground state ion is the state in which all its electrons are in the lowest energy orbitals possible. You can get positive ions by removing electrons until you reach a noble gas configuration.
Ground state ion configurations are the foundation for understanding molecular bonding, properties, and structures. From the electrons in an atom to the differing orbitals and hybridization, the ground state ion configuration throws light on many different atomic properties.
For example, the electronic configuration of Sc²⁺ is 1s²2s²2p⁶3s²3p⁶ 3d¹ 4s.
In conclusion, understanding electronic configuration leads to an understanding of the periodic table.

Answer : The correct expression for equilibrium constant will be,
Explanation :
Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.
The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.
As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.
The given equilibrium reaction is,
The expression of will be,
Therefore, the correct expression for equilibrium constant will be,
Answer:
for the process is -375 kJ

Though the sun emits all of the different kinds of electromagnetic radiation, 99% of its rays are in the form of visible light, ultraviolet rays, and infrared rays (also known as heat). hope this helps
Answer: The partial pressure of the oxygen is 698 torr
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : =total pressure of gases = 720 torr
= partial pressure of = ?
= partial pressure of = 22 torr
Thus the partial pressure of the oxygen is 698 torr
