In carbondioxide: CH4 + 3 O2 ==> CO2 + 2 H2O
Methane burns in oxygen and gets oxidised. Carbon is oxidised to carbon dioxide, hydrogen to water.
Oxygen, Carbon, Hydrogen. <- There are three new ones.
Hydrogen gas, H2.
When sugar burns, it creates a new substance. It's not possible that it's a physical change. So, it's a chemical change !

it burns and seperates actually it burns and oxygen burns it , methane is the gas that we mostly use in southern countries for cooking

Hydrogen is a colorless gas that burns with oxygen. If substances will burn in air, those same substance will burn better in oxygen.

Often it's an oxide. For example, carbon burns in air to form its oxides, carbon monoxide and carbon dioxide. However, there are other possibilities. Hydrogen burns in oxygen to produce water.
combustible?
when magnesium burns in air a white powder called magnesium oxide is formed which is a new substance this is the chemical change
yes, hydrogen gas burns with a pop!
It burns.
