Answer: Oxygen, Beryllium, Lithium, & Fluorine
Explanation:
theoretically it might not be the answer be
This is a
redox reaction where oxidation and a reduction occur.
<span>Here, Mg goes to Mg²</span>⁺ <span>by changing
its oxidation
number from 0 to +2 while S goes
to S²</span>⁻ <span>by reducing its oxidation
state from 0 to -2 .
Hence Mg is
oxidized by S in the
reaction.</span>
Reducing agent <span>is a substance which reduces other
substance by oxidizing itself. Hence, the reducing
agent of this reaction
is <span>Magnesium.</span></span>
