Experimenting: Yeast, Hydrogen Peroxide Chemical Reaction (fire)


Introduction: Experimenting: Yeast, Hydrogen Peroxide Chemical Reaction (fire)

Experimenting with Yeast and Hydrogen peroxide. When Hydrogen Peroxide (2 H2O2) reacts with yeast it makes water (H2O) and Oxygen (O2) 2 H2O2 -> 2 H2O+O2 im just board and want to share my chemical reactions with others.
It relights the piece of wood because the air inside the cup is so rich it changes the flash point (correct me if im wrong)

    Hi i make shooting things!
    I'm ChemGirl and I noticed that your post information is incorrect. Your chemical equation is incorrect, because you for got to add the chemical formula for yeast. However, since yeast is a complex structure, there isn't a chemical formula for yeast.

    Yeast is a catalyst and does not undergo a chemical change and therefore is not written as part of the chemical reaction but noted above the arrow.

    You spelled board wrong it's bored.

    if the gas is heavier than air you can pour it, if it is lighter than air you cant. http://chemistry.about.com/od/funfireprojects/a/candle-science-magic-trick.htm for reference

    Yes, however O2 is not significantly heavier than air, and in this situation there was no gas being poured.

    ...and yes I know that you would have to light it first. I am just curios if it would make lighting a campfire easier. 

    Liver may be used with hydrogen peroxide for a similar reaction, in which catalase is produced liberating lots of oxygen, at which point you can use a candle or similar for re-ignition

    everything cool has science in it. like, for instance, if you burn something with liquid oxygen, the oxygen rich environment makes it explode. which is cool.

    This is dangerous when you mix the resulting oxygen with something like hydrogen, gasoline, or anything that burns. There's a reason oxygen canisters have a warning about not operating near a flame, cigarette, etc.

    I love simple pyro experiments like this. Any other ones that someone can suggest? I'm working on getting potassium nitrate for flash powder/smoke bombs, but I have magnesium.
