Answer: See explanation
Explanation:
The explanation for why solid sodium chloride can't conduct electricity while molten sodium chloride can is explained below:
Ionic compounds that are in their solid state like sodium chloride have their ions fixed in position. Due to this reason, the able to move, therefore we can say that the solid ionic compounds cannot be able to conduct electricity.
On the other hand, ionic compounds in their molten state, are free to flow unlike when they're in their solid state and therefore we can say that molten sodium chloride can be able to conduct electricity.
Your answer would be (D), Noble Gases, or Inert Gases - The far right on the periodic table is also known as Group(0)., or Group 18 on the periodic table. Elements in this group includes, Neon(NE), Argon(AR), Krypton(KR), Xenon(XE), and Radon(RN).

Nitric acid and calcium hydroxide react to form calcium nitrate and water.
The molecular equation is as follows:
2HNO3 (aq) + Ca(OH)2 (aq) = Ca(NO3)2 (aq) + 2H2O (l)
So the formula of calcium nitrate, the salt formed in this reaction is Ca(NO3)2 .
Water here seem to be the only real product. It is formed from the OH+ of the hydroxide and the H+ of the acid which combine to form two water molecules.
Calcium and Nitrate ions remain unchanged before and after the reaction and are thus known as spectator ions.
Answer: E
