Question

Magnesium oxide is formed by:
1melting Magnesium
2burning Magnesium ribbon
3reacting Magnesium with water
4reacting Magnesium with Sulphur

Answer 1

Magnesium oxide is produced by the calcination of magnesium carbonate or magnesium hydroxide. The latter is obtained by the treatment of magnesium chloride solutions, typically seawater, with limewater or milk of lime. Mg 2+ + Ca (OH) 2 → Mg (OH) 2 + Ca 2+ Calcining at different temperatures produces magnesium oxide of different reactivity.
