Magnesium reaction with oxygen

Back

Magnesium burns vigorously and reacts with oxygen from the air to form magnesium oxide.

Front

Word equation for magnesium and oxygen

Back

Magnesium + oxygen → magnesium oxide

Front

Magnesium oxide formation

Back

Magnesium reacts with oxygen even without heating, forming a thin layer of magnesium oxide.
