The unheated sample (magnesium metal) is white in colour and after combustion, it results in the formation of oxide of magnesium, which is grey in colour.

On addition of HCl to the unheated sample, Magnesium chloride is formed along with liberation of hydrogen (bubbling).

Addition of HCl to the heated sample results in the format...
