CaCl2 is a good conductor of electricity when dissolved in water.

Answer:

CaCl_2

Explanation:

We have to keep in mind that a <u>good conductor</u> would be a substance that has the ability to produce <u>ions</u> (<u>charged species</u>). These species are responsible for the electricity conduction on water.

Therefore, we have to check which ones of these compounds will produce <u>ions in water</u>. For N_2 and O_2 we have <u>diatomic</u> molecules (also gases) this type of molecules don't have the ability to produce ions due to his simplicity, they already are <u>very stable</u>.

In the sugar molecule C_6H_12O_6 we have a <u>covalent compound</u>. The ions are produced by <u>ionic compounds</u>. So, this molecule can be discarded too.

For CaCl_2 we have an ionic compound that have the ability to produce ions:

CaCl_2~~->~~Ca^+^2~+~2Cl^-

So, this is the compound that would be a good conductor due to the Ca^+^2 and the Cl^- ions.

I NEED HELP FAST!!!!! Can you tell me about the location of electrons in atoms and how energy affects their location??? I have a
Art [367]
Their locations can vary depending on the molecule they are associated with but they are usually in a "cloud " that is on the outside of an atom/molecule and if the atom is unstable the  electrons tend to be located farther away from the atom.
