Is mitochondrion a participant in photosynthesis?

It takes the products of photosynthesis and uses cellular respiration to produce ATP, but it does not take part in the actual reactions of photosynthesis. The mitochondrion can, however, give carbon dioxide to the chloroplasts, so it is able to give reactants to the process.

What is produced when a fuel burns?

It depends on the fuel and how well it burns. For example, methane, ethane, propane, butane, petrol, ethanol, sugar, etc. will give water & carbon dioxide if burnt fully; however, imperfect burning can produce carbon monoxide or carbon. Burning hydrogen, on the other hand, produces water.


What is the Empirical formula for carbon dioxide?

Carbon dioxide! We give off carbon dioxide, plants give off oxygen. Its one carbon atom and two oxygen atoms.
