Question

3. If magnesium is gently heated ,it forms * 1 point
A.)Magnesium sulphide
B..) Magnesium nitride
C.). Magnesium oxide D.) None​

Answer 1

The correct option is C) magnesium oxide

Explanation:

• When magnesium is heated, a chemical reaction takes place.
• Magnesium reacts with oxygen in the air upon heating, giving rise to magnesium oxide.
• The reaction is exothermic and hence heat is released as a result of this reaction.
• This reaction can be written as: 2Mg+O2→2MgO+heat
