Question

Give one way in which the formation of magnesium oxide differs from the formation of the sodium chloride?

Answer 1

Answer:

Calcining at different temperatures produces magnesium oxide of different reactivity. Sodium chloride is formed when sodium atoms interact with chlorine atoms.

Explanation:

Answer 2

To form Na_2O compound, 2 sodiumions are needed to neutralize the charge on oxygen ion. This will loose 2 electron to form Mg^{2+} ion. This will gain 2 electrons to form O^{2-} ion. To form MgO compound, 1 magnesiumion is needed to neutralize the charge on oxygen ion.
