What gas is evolved when hydrogen peroxide is decomposed?

I have to go with Dan, you get water and the release of oxygen

2Cu(NO3)2 ----> 2CuO + 4NO2 + O2\nOBSERVATION: brown, choking fumes of NO2 evolved; black solid i.e CuO settles at the bottom\n\n2FeSO4 ----> Fe2O3 + SO2 + SO3 \nOBSERVATION: white fumes of SO3 evolved and reddish brown solid i.e. Fe2O3 formed\n\nEDIT: The above equation for iron(II)sulphate may be a supposed characteristic for its thermal decomposition relating to that of copper(II)nitrate above, but Chaos, O2 will not be evolved here, because SO3 will not get reduced to O2, even on strong heating.

It's depends on the availability of oxygen.  In the presence of O2, bacteria will convert most of the organic material to carbon dioxide gas (CO2).  In the absence of O2, they'll mostly produce methane gas (CH4).

Thank you punnet pundit. I was thinking the same thing. \n\nWhen combining Hydrogen and Oxygen one will get water or hydrogen peroxide. Simple enough. But that's not all there is to it. Just mixing the two doesn't cut it. The mixture must first gain enough energy to react. This is called it's Activation Energy. Which is the amount of energy it needs to absorb in order to carry out a chemical reaction. In the case of water the reaction is spontaneous and once started will continue until there is no longer enough reactants to form products. \n\nIn the case of water the reaction is explosive and quite violent. Liquid Oxygen and Liquid Hydrogen are used in space ships, because the reaction is enough to give the rocket a signifigant amount of upward force. The product is steam really because the water is way above 212 degrees F. but if this is condensed onto something below that temperature you get pure water.\n\nHydrogen peroxide slowly over time can break down in light. That's all I really know about it.

you'll have a mixture of hydrogen and oxygen

two parts hydrogen.......one part oxygen...hence.....H2O

Please do your own home work.\n\nI suspect you are missing a symbol, it probably should be,\nN2O4  <==>  2NO2\n\nThink about how each of the changes will effect the equilibrium of the reaction.

The balanced equation for the reaction is:\n\n2 H2O2 --> 2 H2O + O2\n\n1]  If one mole of Oxygen is produced, the 2 moles of Hydrogen peroxide would be needed.  One mole of Hydrogen peroxide contains 2*H + 2*O = 2(1) + 2(16) = 2 + 32 = 34 grams.\n\n2 moles of Hydrogem peroxide = 2*34 grams = 68 grams.\n\n2]  Is it 0.3 moles or 0.3 cubic decimeters of Hydrogen peroxide?\n\nAssuming 0.3 moles, then from the above, 0.15 moles of Oxygen would be produced.  The volume would be:\n\n0.15 moles * 24 cubic dm/mole  = 3.6 cubic dm of Oxygen at rtp.

None is EVOLVED.  Evolving means adapting and changing.  Methane and Carbon Dioxide are EXPELLED when we fart.

Superoxide is a reactive anion and free radical, formally O2-. It is produced most easily by burning rubidium or caesium in oxygen. Other superoxides, including potassium superoxide, are also known. It has an unpaired electron, is not particularly stable, and spontaneously decomposes into peroxide and oxygen over time. In phagocytes, superoxide is produced in large quantities by the enzyme NADPH oxidase for use in oxygen-dependent killing mechanisms.\n\nHydrogen peroxide (H2O2) is a clear liquid, slightly more viscous than water. It has strong oxidizing properties and is therefore a powerful bleaching agent that has found use as a disinfectant, as an oxidizer, and in rocketry (particularly in high concentrations as high-test peroxide (HTP) as a monopropellant), and in bipropellant systems.

The electrolysis of water with the o2 and h collected in seperate test tubes a lit match will ignite the hydrogen...POP! and a matchstick that has been blown out but still has a hot ember will burst into flame in the oxygen.

Carbon (C), Hydrogen (H), and Oxygen (O)

Hydrogen peroxide give hydrolysis of complexes, since the hydrogens on water ligands are VERY acidic the ligands become hydroxides and the complex usually ends as a metal oxide. Ammonia acts as a lewis base with the complex accepting the electron density and most likely kicking off some chlorides. HCl just storms the complex with chloride ions. And The metal oxygen bonding is much stronger than the metal chloride bond (mainly due to differences in pi backbonding) so the chlorides shouldnt do much to the original complex. \n\n\nAs for the exact molecular formula of what should happen, try asking god. For the answer that your teacher wants try reading a book.

it is a chemical reaction and the gas is c02

The following is an overall (net) reaction:\n\n    H2O2 → H2O + O2\n\nThis reaction is catalysed by the enzyme catalase. For a detailed mechanism have a look at the following link.

By itself, water is an unreactive substance by nature. So you cannot separate oxygen and hydrogen from the water molecules. However, there is only one ay in hich this canbe done: electrolysis.\n\nIt involves the passage of an electric current into a liquid, which naturally conducts electricity. Electrodes are used to pass the electric current. At both the electrodes, gases are evolved, depending upon the liquid.\n\nSome acid or alkali should be added to water for the evolution of gases, namely hydogen and oxygen at the electrodes.\n\n\n\nIt can be mass-produced, but the process is too costly. An application could be to use hydrogen in hydrogen powered cars to replace the more polluting petrol powered cars. \n\nMoreover, oxygen is also obtained by the fractional distillation of liquid air. It involves cooling air by decreasing the its pressure by placing them in special containers, capable of bearing atmospheric pressure. This process is more economical, compared to electrolysis. Liquid oxygen and hydrogen is used to power rockets in order to propel them into space. This process for the production of liquid oxygen and hydrogen is mass produced nowadays to power rocket and hydrogen powered cars. \n\nThanks

Ozone spontaneously decomposes.  If we filled all the holes, the ozone would turn to oxygen in a matter of minutes and the holes would be back.  "Holes in the ozone layer" are a myth propogated by those who would like to reverse the industrial revolution, but who would still insist on driving their BMW's.
