When Magnesium burns, it is actually combining with oxygen in the air to form a new compound, magnesium oxide. If we were to carefully weigh a piece of magnesium before and after burning it, you would see that its weight increased by about one third. For example, if you start with 100 grams of magnesium, after the burn you would end up with about 130 grams of magnesium oxide. The fact that the magnesium oxide you create by burning is powdery, means that it takes up more space (size or volume) than the solid magnesium did.
Magnesium becomes heavier after it is burnt. This is because the magnesium has chemically bonded with oxygen to form magnesium oxide. The oxygen adds the extra weight.
When magnesium ribbon reacts with hydrochloric acid (HCl), magnesium chloride forms along with hydrogen gas being produced as a byproduct. The chemical equation for this reaction is: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g)
Mg(s) + 2HCl(aq) ---> MgCl2(aq) + H2(g)
The colour when coal is burnt is white,when it become ash
That is true. Coal is composed mostly of carbon, and when it burns it turns into carbon dioxide, which is a gas. The ash is just a minor residue of the non-carbon part of the coal. Whereas, magnesium when it burns turns into a solid material, magnesium oxide; it gains oxygen from the air and therefore increases in weight.

Burning (oxydation) and transformation in magnesium oxide.
it turn white as ash
The white ash obtained by burning magnesium ribbon is magnesium oxide (MgO). When magnesium burns in the presence of oxygen, it reacts to form magnesium oxide, which appears as a white powdery ash. Magnesium oxide is commonly used in various industrial applications, as well as in manufacturing pharmaceuticals and supplements.
When magnesium ribbon reacts with hydrochloric acid (HCl), magnesium chloride forms along with hydrogen gas being produced as a byproduct. The chemical equation for this reaction is: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g)
The result would be that the white ash of magnesium ribbon reacts with water to form magnesium hydroxide, which will turn the red litmus paper blue due to the basic nature of the resulting solution.
Mg +2HCl >> MgCl2 + H2 A salt and hydrogen gas.
According to the Law of Conservation of Mass, matter can neither be created nor destroyed, only change forms. Therefore, if you burn magnesium inside of a closed container, the mass will remain the same. ---- However you will get heavier ash than you had magnesium as the Oxygen in the air in your container will be transfered. But Total Mass is conserved.
Magnesium weight more than ash. White ash is magnesium oxide.
Magnesium weight more than ash. White ash is magnesium oxide.
Mg(s) + 2HCl(aq) ---> MgCl2(aq) + H2(g)
When magnesium ribbons are burned, they react with oxygen in the air to form magnesium oxide ash (MgO). This ash is a white, powdery substance that is the result of the oxidation of magnesium.
