Hydrogen combines with oxygen when it is burned and produces water as a by-product. Insignificant amounts of nitric oxides are also formed in areas around the combustion zone.
Water can be readily split into hydrogen and oxygen using electricity. This process is known as electrolysis. The hydrogen captured in this process can be burned, where it combines with oxygen from the air and becomes transformed into water once again. This process can be repeated in an ongoing cycle, as long as there is a constant input of electricity into the system. However, it takes more electricity to split the water into its component parts than could be produced by burning the hydrogen.Learn More
Polypropylene is produced from liquid or gaseous propene, which is derived from gas oil, naphtha, ethane and propane. The process of creating polypropylene from propene is known as polymerization.Full Answer >
Natural light is produced by natural processes, such as the sun and stars. By contrast, man-made devices, such as flashlights and light bulbs, emit artificial light. All forms of light require the release of energy, and in the natural world, this includes explosions, fires and similar phenomenon.Full Answer >
A burning candle is an example of a chemical change because the paraffin wax, which is a hydrocarbon, undergoes a chemical reaction with oxygen to form water and carbon dioxide gas. Because the chemical structure of the paraffin has been altered, this is a chemical change.Full Answer >
Oxidation, in common parlance, is the process or product of a substance combining with oxygen. The oxidation process may be slow as when a hammer left outside overnight rusts (iron changing to iron oxide). A faster example of oxidation is when a cut apple or banana turns brown.Full Answer >
