Question

on burning a clean piece of magnesium ribbon in hairs are white hat is obtained.what type of change is observed?. what what is observed when Magnesium is burnt and write the chemical formula of the white Ash?

Answer 1

When magnesium burns, it is actually reacting with oxygen in the air and not with fire. Fire is what we call the heat and light produced when things burn. Magnesium reacts with oxygen to make a compound called magnesium oxide. The bright light results because this reaction produces a lot of heat.The increase in mass is due to the fact that oxygen from the air has combined with the magnesium to make magnesium oxide, MgO. The chemical equation, Mg + O2 MgO shows this reaction but it needs to be balanced to make 2Mg + O2 2MgO.

Answer 2

magnesium oxide is the white ash.

mg+O2 - mgO

nature is basic.
