Correct option is C
The correct answer is (c) Magnesium oxide.
When a magnesium ribbon is burned with a spirit lamp, it reacts with the oxygen in the air to form magnesium oxide (MgO). This is a white, powdery substance.
Information Booster:
Reaction: The chemical reaction that takes place is:
2Mg + O₂ → 2MgO.
Magnesium (Mg) reacts with oxygen (O₂) in the air to form magnesium oxide.Properties of Magnesium Oxide:
- It is a white powder and has high melting point.
- It is basic in nature and reacts with acids to form magnesium salts.
Uses of Magnesium Oxide:
- Used in the production of refractory materials (materials that can withstand high temperatures).
- It is also used as an antacid for treating acidity in the stomach.
