What changes happen to magnesium powder after you heat it?Heating Magnesium Powder?
As magnesium powder has a large surface area, It will combust and react with oxygen in the air to form magnesium oxide, a white powder and a base. The solid material will convert from a metallic grey colour to a white powder.
The equation is as follows:
2Mg(s) + O2(g) -----------%26gt; 2MgO (s)Heating Magnesium Powder?
It will combine with oxygen and burn very hot very fast. Like white hot! watch out, it's the stuff that makes the best and brightest and loudest white fireworks!
If you heat it in air
It reacts with nitrogen and oxygen
2Mg + O2 -------%26gt; 2MgO
3Mg + N2 --------%26gt; Mg3N2
