Burning (oxydation) and transformation in magnesium oxide.
it turn white as ash
Yes, when magnesium ribbon burns, it reacts with oxygen in the air to produce magnesium oxide, which appears as a white ash. This combustion is highly exothermic, resulting in a bright white flame. The white ash formed is primarily magnesium oxide, a powdery substance that can be seen after the reaction.
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)
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.
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.
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.
Burning magnesium reacts with oxygen in the air to form magnesium oxide, which is a white ash-like substance.
