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.
I would say letter C.
"the oxygen atom<span> attracts </span>electrons<span> a bit </span>more<span> strongly </span>than the hydrogen atoms. The unequal sharing of electrons<span> gives the </span>water<span> molecule a slight </span>negative charge<span> near its </span>oxygen atom <span>and a slight </span>positive charge<span> near its </span>hydrogen atoms<span>."

Answer:
Option 4th, TRUE . Its pH becomes equal to 7.
Explanation:
[H₃O⁺] = [OH⁻]
pH = pOH → 7
[H₃O⁺] > [OH⁻] → pH < 7 ⇒ acidic solution
[H₃O⁺] < [OH⁻] → pH > 7 ⇒ basic solution
pH = 0 does not exist.
Answer: the upper right portion of the periodic table.
Explanation:
Appropriate units for the speed of a chemical reaction, the reaction rate, are M/s
