Ik it's not magnesium because that was my first answer. The correct answer would be Sulfur. Sulfur is a non metal. All the other answers are good conductors of heat

<u>Answer:</u> The balanced half reaction is written below.
<u>Explanation:</u>
Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
When oxygen gas is reduced to oxide ions, the number of electron transferred are 2
The chemical equation for the reduction of oxygen gas to oxide ions follows:
Hence, the balanced half reaction is written above.
Answer: Option (d) is the correct answer.
Explanation:
When we dissolve an ionic compound in water then it readily dissociates into ions.
This is because ionic compounds are polar in nature and like dissolves like. Since, water is also polar in nature hence,
For example, NaF is an ionic compound as it is formed by transfer of an electron from sodium atom to fluorine atom.
So, when NaF is dissolved in water then it dissociates into and ions.
As electric current occurs due to movement of electrons or ions. Therefore, a solution with and ions is able to conduct electricity.
Thus, we can conclude that if you want to conduct an electrical current, then dissolving solid NaF in water would produce a solution capable of this.
