Burnt sugar is also called black jack in the baking industry. When this term is referred to as a flavor, the reference is to a deep, caramelized flavor, not an actual burnt flavor. To confuse things further, simple caramelized sugar is sometimes referred to as burnt sugar.

Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.

Air contains about 21 percent oxygen, and most fires require at least 16 percent oxygen content to burn. Oxygen supports the chemical processes that occur during fire. When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.).

Air will never spontaneously combust, nor can it be made to burn non-spontaneously. Air is mostly nitrogen, which is not flammable.

Tiny sugar particles burn up almost instantly because of their high ratio of surface area to volume. Table sugar, or sucrose, is flammable under the right conditions, just like wood (which is made of cellulose, or lots of sugar molecules linked together).

Sugar is made of carbon, hydrogen and oxygen atoms. When heated over a candle, these elements react with the fire to turn into a liquid. The heat causes the sugar’s atoms to combine with the oxygen in the air, forming new groups of atoms. Energy is released in this chemical reaction in the form of smoke and black soot.

As they burn the glucose fuel, they produce water and carbon dioxide. Your heart beats faster pumping more fuel and oxygen to the cells and taking carbon dioxide away from the cells.

When glucose (C6H12O6) reacts with oxygen, carbon dioxide and water are produced. The balanced equation for this reaction is: If 12 moles of oxygen react, The reaction consumes moles of glucose (C6H12O6). The reaction produces moles of carbon dioxide and moles of water.
