Methane is correct
True
Plants don't combine hydrogen and carbon dioxide directly; if they did (and did so in a 1-to-1 ratio), the result would be formaldehyde. Instead, plants combine carbon dioxide and water in such a way as to produce carbohydrates (particularly glucose) and oxygen in a multi step complex synthetic process.
Human beings give off carbon dioxide. Some bacteria give off methane or hydrogen.
Manganese dioxide is a catalyst for the decomposition of hydrogen peroxide.
The ingredients are carbon dioxide and water in the presence of sunlight. The water is split using sunlight energy into hydrogen and oxygen. Hydrogen is then used to create energy that the plant can use while some oxygen is expelled as a waste product. Carbon dioxide is rearranged into carbon compounds, and the extra 6 oxygen molecules combine with hydrogen to create water which is also expelled as a byproduct.
methane
Carbon and oxygen combine to form carbon dioxide, CO2, during the combustion of fuel.
It's methane. ^^

Plants split Carbon Dioxide (CO2) and combine Hydrogen (H) with Oxygen (O2) to make Water (H20)
It most certainly is. I can get an engine to run on hydrogen. All that is produced at the tail pipe is water vapor and carbon dioxide. When hydrogen and oxygen combine and a ignition source is present, water is formed along with a powerful explosion. Oxygen and Hydrogen are very volatile and are dangerous to combine without a controlled environment. The interesting thing is that Oxygen and Hydrogen combine to form water. What do firemen use to put out a fire? Oxygen and Hydrogen or H2O. If someone can figure out how to release hydrogen from water cheaply, you could power a car off water.

H2O2 is a common name for hydrogen dioxide
dioxide is di(two)oxide(oxygen). no hydrogen.
Is this HO2 for hydrogen dioxide, never heard of it in 'normal' life
Carbon dioxide contains carbon and oxygen. Water contains hydrogen and water. Therefore, to combine with oxygen to form CO2 and H2O, butane must contain carbon and hydrogen.
