Heating a metal in air, which comprises of about 21% oxygen, using an open flame at sufficiently high temperature can possibly cause a reaction with oxygen.

Sodium burns with a brilliant yellow light to form an ionic sodium oxide.

Magnesium burns with a bright white light to form a MgO.

Metals exhibit strong metallic bonding(electrostatic attraction between a lattice of positive ions and a sea of delocalised electrons) and therefore require high amounts of energy to break. By burning a metal using a normal flame, reaction with oxygen is more likely to occur than to melt the metal, i.e. the latent heat of fusion is too high.

Are carbon atoms changed during burning?

Burning is a combustion reaction, which is a type of oxidation-reduction reaction. During combustion, carbon is oxidized. This means that it oxidation state becomes more positive, since it loses electrons during the reaction (it is bonded to the more electronegative oxygen after the reaction, whereas it was bonded to less electronegative hydrogen before the reaction).


What does oxidation reaction means using oxygen?

Oxidation means addition of oxygen. When oxygen is added to a compound, it is said to be oxidised.


What do you mean by the term combustion?

Combustion is another word for burning. It means a chemical reaction with an oxidising agent, usually oxygen itself, producing new substances and releasing heat.


Why is anything burning a chemical change?

Burning is oxidation, which means that the compounds in whatever is burning are being chemically combined with oxygen.


What conditions are necessary for burning to take place?

Burning, or combustion, requires three main elements: fuel, oxygen, and heat. The fuel provides the substance to burn, oxygen acts as the oxidizer, and heat initiates and sustains the chemical reaction between the fuel and oxygen. Without any of these elements, burning cannot occur.


What is the thing that not need fire for burn?

When we talk about "burning" it generally means a chemical reaction with oxygen from the air, which produces heat. Nuclear scientists and engineers also talk about "burning" or "burnup" of the nuclear fuel, in this case there is no fire or chemical reaction, so perhaps this is what you have in mind.


What does combustion refer to?

combustion means burning of something using Oxygen gas


Is burning sugar endothermic?

No, burning sugar is exothermic because it releases energy in the form of heat and light. The chemical reaction between sugar and oxygen produces carbon dioxide and water, along with energy that is released in the form of heat and light.


Is magnesium ribbon burns an endothermic reaction or an exothermic reaction?

The reaction is highly exothermic as heat energy is released from the system to the surroundings whereas in endothermic the heat is absorbed from the surroundings into the system and you can also observe or see the smoke coming out of the apparatus in which the reaction is occurring or taking place.Heat energy is being released in the form of smoke.Therefore the reaction is exothermic.


Is the reaction between carbon and oxygen to form carbon monoxide exothermic?

Yes, the reaction between carbon and oxygen to form carbon monoxide is exothermic. This means that the reaction releases energy in the form of heat as it proceeds.


What word beginning with r means taking away oxygen in a chemical reaction?

reduction


Does burning magnesium release energy?

ofcourse. release of energy(in the form of light and heat ) is always involved with combustion
