Question

select the correct answer.
when magnesium combines with sulfur to form magnesium sulfide, it is oxidized to ( mg^{2+} ). which statement is true about this reaction?
○ a. it involves gain of electrons.
○ b. it involves loss of electrons.
○ c. it involves loss of oxygen.
○ d. it involves gain of hydrogen

Explanation:

Step1: Understand oxidation and reduction

Oxidation is loss of electrons and reduction is gain of electrons.

Step2: Analyze the reaction of magnesium

Magnesium (Mg) is oxidized to \(Mg^{2 +}\). Oxidation means loss of electrons.

Answer:

B. It involves loss of electrons.
