The magnesium is chemically changed and become magnesium oxide. The oxygen is also chemically changed from an element -oxygen gas, to a solid oxide.
To confuse the answer slightly, they are also physically changed. The magnesium changes from a shiny, malleable lustrous metal to a white powdered oxide. The oxygen changes from a colorless gas to a solid oxide.

that's why.

Why burning of magnesium in air is chemical change?
magnesium burns in oxygen to form magnesium oxide. and hence this is a chemical change
Mixing magnesium and the product of burning magnesium with hydrochloric acid is it a physical or chemical change?
Is it a chemical change.
When magnesium burns in air is it chemical or physical change?
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.
Is burning magnesium a physical change?
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
Is burning magnesium oxide a chemical change or physical?
If you burn anything, no matter what it is, you are activating a chemical change.
Is magnesium burning in the air a chemical change?
Yes. Burning anything is a chemical change.
Is burning a magnesium ribbon a physical change?
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.

Mixing magnesium and the product of burning magnesium with hydrochloric acid is it a physical or chemical change?
Is it a chemical change.
Is burning a strip of magnesium ribbon a chemical or physical change?
This is a chemical change. The reaction is: Mg + O ---> MgO

Why is the burning of magnesium considered a chemical change?
During burning magnesium is transformed in magnesium oxide - a chemical reaction:2 Mg + O2 = 2 MgO
When magnesium is burning in the presence of oxygen what are some evidence that a chemical change is occurring?
It shows the change of when the magnesium is burning in the presence of oxygen.

Is burning magnesium oxide a chemical change or physical?
If you burn anything, no matter what it is, you are activating a chemical change.
Is burning a fire a physical or chemical change?
Burning is a chemical change.
