Web19 nov. 2015 · The color in the burning salts comes from the energy contained in their electrons — the negatively charged particles that move around the outer edges of atoms. These electrons become excited when energy is added — for instance, when you set the salt on fire. As the salt burns, the extra energy is lost — as light. WebCombustion is another type of chemical reaction. Combustion usually includes oxygen and usually produces heat and light in the form of flame. A familiar example of combustion is the burning of a hydrocarbon, such as methane, in the presence of oxygen; the products of this reaction are carbon dioxide and water: CH 4 + 2O 2 → CO 2 + 2H 2 O
