54. Magnesium oxide can be obtained by heating
(1) MgCO,
(2) Mg(NO),
(3) Mg(OH),
(4) All​

Answer 1

Answer:

When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. ... Oxygen and magnesium combine in a chemical reaction to form this compound. After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product.

Explanation:

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 lime. Calcining at different temperatures produces magnesium oxide of different reactivity.
