Answer: option C. Copper (II) chloride
Explanation:
To name CuCl2, we need to know the oxidation state of Cu in the compound as chlorine always have oxidation on —1 in all its compound. The oxidation state of Cu can be calculated as follows:
Cu + 2Cl = 0 (since the compound has no charge)
Cl = —1
Cu + 2(—1) = 0
Cu —2 = 0
Collect like terms
Cu = 0 +2
Cu = +2
Therefore, the oxidation state of Cu in CuCl2 is +2.
The name of the compound will be copper(ii) chloride, since cupper has oxidation state +2 in the compound.
Going down a group the acid strength increases because the bond strength decreases as a function of increasing size of the nonmetal, and this has a larger effect than the electronegativity.
<h3>What is Electronegativity? </h3>
A functional group or an atom's propensity to draw electrons to itself is referred to as its "electronegativity," which is a chemical attribute. An atom's atomic number and the separation between its valence electrons and charged nuclei have an impact on how electronegativity is determined.
For an atom to be able to draw electrons, it must be electronegativity. It varies in direct proportion to the gap between an atom's attraction to the electron and its potential for ionisation.

Answer:
It connects the two half‑reactions.
Explanation:
A salt bridge is a laboratory device used to connect the oxidation and reduction of half-cells of a galvanic cell. It prevents the cell from rapidly running its reaction to equilibrium.
Salt bridge or a porous plate connects the solutions of the half-cells that allow ions to pass from one solution to the other. This process balances the charges of the solutions and allows the reaction to continue.
Answer:
electrical
Explanation:
It wouldnt be kinetic or potential since both of those have to do with motion, and it would not be heat because heat does not power a light bulb. Therefore, the answer is electrical.
