Why is magnesium cleaned before burning?

Magnesium ribbon should be cleaned before burning it in air to remove the oxide layer from it which may prevent or slow down the burning of magnesium ribbon.

to remove the layer of basic magnesium carbonate to remove the layer of Mg Oxide

Magnesium is an extremely reactive metal. When stored, it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper for removing this layer so that the underlying metal can be exposed to air.

Magnesium ribbon is cleaned with the sand paper before use because its surface is covered with certain type of grease, in the presence of which the Mg cannot work proper and faster.

magnesium has a layer of magnesium oxide so it is rubbed by sand paper before burning other wise magnesium will not burn

what is the compound for burning magnesium

The reactants of hen burning magnesium metal is: Magnesium and oxide  

After burning of magnesium MgO (magnesium oxide) is obtained.

No. Burning magnesium, or burning anything for that matter, is a chemical change. The magnesium reacts with oxygen to form magnesium oxide, and to some degree reacts with nitrogen to form magnesium nitride.

To remove the layer of magnesium oxide from the surface which would inhibit reaction.

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…

Because atom cant just disappear

Yes. Burning anything is a chemical change as magnesium is converted to magnesium oxide.

fart head bum poo in your pooy face

This is a chemical change, like any other burning reaction: magnesium is turned into magnesium oxide by burning reaction with oxygen (from air). 2Mg + O2 --> 2MgO

This is chemical: magnesium is turned into magnesium oxide by burning reaction with oxygen (from air). 2Mg + O2 --> 2MgO

Precautions to be taken while Burning Magnesium with Oxygen: As we know burning magnesium is bright, apart from this it produces some ultraviolet light. We should avoid looking directly at it. The burning magnesium is very hot so we should not touch it. As magnesium burns in the presence of carbon dioxide, the flame from burning magnesium does not put out from a CO2 fire extinguisher. So we should use a dry chemical fire extinguisher…

During burning magnesium is transformed in magnesium oxide - a chemical reaction: 2 Mg + O2 = 2 MgO

equation for burning a piece of magnesium ribbon: 2Mg + O2 -----> 2MgO

Magnesium is flammable; after burning magnesium oxide is formed.

MgO, Magnesium oxide.

By burning magnesium. It will react with oxygen in the air, forming magnesium oxide.

Magnesium (Mg) + Oxygen (O) -> Magnesium oxide (MgO)

magnesium + oxygen gas ----D magnesium oxide

Magnesium oxide with traces of magnesium nitride

magnesium look like white powder after burning in air. magnesium burns in air n react with atmospheric oxygen n forms magnesium oxide which is a white powder.

why Covering the crucible with its lid as soon as the magnesium starts burning

Yes, the burning of magnesium ribbon is an oxidation-reduction reaction.

It shows the change of when the magnesium is burning in the presence of oxygen.

The flame of magnesium is white.

Burning of magnesium (or anything else) requires continuing combination with oxygen. If a burning piece of magnesium is transferred to an atmosphere of nitrogen, no additional magnesium can react with oxygen because none is available for reaction.

Strange question. either you have lit some magnesium (in which case you have observed it burn) or not. The evidence is in the burning.

It is called Magnesium Oxide

Magnesium nitride (Mg3N2) is obtained.

No, magnesium can continue tor burn in nitrogen to form magnesium nitride, Mg3N2

No fundamentally they are the same process, oxidation.

It will stop burning

Burning magnesium will result in a brilliant white light.

Burning (oxydation) and transformation in magnesium oxide.

A white color during magnesium burning.

By magnesium reacting with oxygen. Mostly its heating or burning it which causes a white powder- magnesium oxide.

When burning magnesium in nitrogen, magnesium nitride is formed. 3Mg + N2 ---> Mg3N2

magnesium burns in oxygen to form magnesium oxide. and hence this is a chemical change

no, when exposed to air magneesium is tarneshed, but it can be lusterous if it is cleaned.

The magnesium is burned and reacts with the oxygen in the air. 2Mg + O2 → 2MgO Magnesium + Oxygen gas → Magnesium oxide

When you burn magnesium, you are taking two elements, magnesium and oxygen, and combining them to form a compound, magnesium oxide. That is synthesis.

Burning magnesium (or burning anything) can be described as a chemical reaction, or as a chemical change. It is not a property. However, the capacity of being able to burn, also known as flammability, is a chemical property.

Burning is a chemical change.

Yes. Burning anything is a chemical change.
