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 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 oxidation reaction means using oxygen?
Oxidation means addition of oxygen. When oxygen is added to a compound, it is said to be oxidised.
How do you know that a burning of candle wax is an exothermic change?
Because heat is coming out of the reaction, that means it is losing energy
Having below normal oxygen levels in the body tissues and cells?
Hypoxemia means having below normal oxygen levels in the blood.

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 does combustion refer to?
combustion means burning of something using Oxygen gas
Difference between 2O and 2 O in a chemical equation?
2O means two molecules of oxygen involved in the reaction and O2 means two atoms of oxygen which are ready to form a bond after a chemical reaction
If you mixed chlorine argon and sodium together what would you expect to happen?
Sodium will react with chlorine to give you sodium chloride. Sodium will burn out. That means it is exothermic reaction. The argon is noble gas. argon will not take part in the chemical reaction or in the process of burning. Argon will act as a medium to dilute the chlorine. The end products will be same. The time to complete the burning will be little more, when chlorine is diluted with argon gas. This is just like carbon burning in the air and in pure oxygen. Carbon burns brighter in pure oxygen.
What word beginning with r means taking away oxygen in a chemical reaction?
reduction

Is burning sugar endothermic?
Endothermic means absorbing thermal energy, so of course not. There is no such thing as sugar getting cold when it's burning. Burning sugar is exothermic, meaning it releases heat.
What dose irritant mean?
Irritant means it can have a reaction to something for example if you see irritant with a cross on a chemical bottle it means if it has contact with body parts or skin you may have a bad reaction like itching , sourness or burning
