what added to sugar causes it catch fire?

any sort of oxidizer, sugar by itself will "burn", but as you may have learned it isnt complete combustion without a large amount of extra o2 being present.  could have been a permanganate (barium permanganate, magnesium permanganate), however if you hope to acquire some of this yourself, it might be a little hard to come by.  you could always use nitrous oxide too :) N20

Ethanol has a low flash point (-5 C), which is the temperature at which enough vapors in the air can be present to create an explosive atmosphere; a spark or flame can cause an explosion.  It also does burn with a weakly colored flame, making it hard to see.  \nAlso - high-strength ethanol that you can by is called denatured alcohol - there are many kinds, but they are all poisoned with something - methanol, isopropanol, toluene etc. which render it undrinkable.  Don't do it.\nPunch in "MSDS" and "ethanol" into yahoo and pull up a material safety data sheet.

Glucose is oxidized with bromine.

potassium nitrate and sugar equal parts and a wick of some type or at least an ignition source. You can add certain elements to make different colors as well.

The sugar in the mentos reacts with the carbonate in the coke causing gasses to form and pressure to increase inside the bottle, when this pressure is released the gasses will shoot out causing it to "rocket".

Fire if what you are drinking is water.

Pr0n.\n\n\nSeriously, the heat is generated from the oxidation (burning) of fuel (mostly glucose) within the cells (mitochondria).  Just as oxidation of gasoline creates heat & energy, so does the controlled, catalytic (enzymatic) oxidation of sugar - it's what we live on!!

Fire is the result of a combustion chemical reaction in which a hydrocarbon (a compound containing carbon and hydrogen) is reacted with oxygen forming carbon dioxide and water.  This reaction releases a lot of energy in the form of thermal (heat) radiation which is the result of fire.\n\nNote that there are other compounds which react with oxygen to release much energy and form oxides, but they're not relevant with respect to water.\n\nIce is water and not a hydrocarbon so it can not catch on fire.

Lots of smoke.\n\nThe chemical results include nigrogen gas and various forms of burned carbon. Sucrose is such a complecated molocule that it is impractical to determine the products.\n\nWhat you are probably asking is whether or not this is poisones. The answer is no, it will not hurt you, I have tried it. Maybe don't purposefully inhale it... But its okay to be in the smoke.

the most common salt that burns purple is salts with potassium. I'm not sure what gives a black flame test, but sugars such as glucose and surcrose definately "burns" black.

That should only happen with copper or copper salts.\nIt's the oxidation of the copper in the flame.\nAll elements burn differently, this is the basis of how a spectrometer works.

well basically its just a chemical reaction.\n\nSince Soda is basically just made up of sugur,flavoring, water and preservatives. Since Mentos is a heavy peice of candy it sinks to the bottom of the coke bottle which making it easier for more bubbles to be formed from the bottom up. Each Mentos candy has thousands of tiny pits all over the surface. These tiny pits are called nucleation sites - perfect places for carbon dioxide bubbles to form. So thats what causes the eruption and boom it explode.

C6H12O2 + 6O2 --> 6CO2 + 6H2O\n\nis the combustion reaction for glucose.

One that catches on fire like alcohol or gasoline

it burns. Gasoline contains various compounds of carbon (C) and hydrogen (H). When you add oxygen (O) and burn it, chemical reaction results in water H2O (water vapor) and CO2 (carbon dioxide)

It is a metabolic product which ultimately derives from glucose. You may have had some high sugar food stuffs. Then again there is the occasional error.

Oxygen is what fuels fire, but when we blow out a candle there is so much force in your breath that the flame is blown out otherwise it would only make it bigger. Oxygen is highly flammable, carbon-dioxide is a fire suppressant.
