Answer:
Chemical equation:
Sr + S → SrS
Explanation:
Mg react with sulfur and form magnesium sulfate.
Chemical equation:
Mg + S → MgS
The oxidation state of magnesium is +2 it loses its two valance electrons while sulfur gain two electrons to complete the octet. That's why one atom of magnesium combine with one atom sulfur.
Chemical equation:
Sr + S → SrS
The oxidation state of strontium is +2 it loses its two valance electrons while sulfur gain two electrons to complete the octet. That's why one atom of strontium combine with one atom sulfur.
