What is combustion reaction?
Comubustion reactions are those reactions in which organic compound get burnt in the presence of oxygen for the formation of carbon dioxide gas and water molecule.
If the food sample contains the organic compound then it will convert into water and carbon dioxide gas and if it contains the matter in the form of inorganic compounds then it will convert into another product but having the same mass.
Hence if matter of food sample is burned then it will convert into small products as a result of physical or chemical change.
