Synthetic is not a term used to describe imitation pearls. Synthetic, in the case of gemstones, is completely manmade, and it has to have the same structure, constituents, and chemistry as its natural counterpart. No cultured pearl is completely manmade. There is always human intervention, but the mollusk grows the cultured pearl. Of cultured pearls, only tissue-nucleated and keshis have the same structure, constituents, and chemistry as their natural counterparts, but they result from human intervention. So when the two criteria that determine a synthetic gem are applied, there is no cultured pearl or imitation that meets both. Therefore, no cultured pearl or imitation is a synthetic.
It is "clean" because the by-product in the combustion of Natural Gas is water vapor and and carbon dioxide. That is the same products we exhale. That is why it is considered so clean. The main reason is because NG is mainly comprised of methane. Hope this helps! See the link....
The carbon cycle.
Yes, combustion of natural gas is a form of chemical change.
carbon dioxide
3CO2+8N2+4H2O+heat
Rapid oxidation -- or combustion -- produces carbon dioxide, CO2, and water vapor, H2O.
oxygen
Yes, incomplete combustion of natural gas can produce aldehyde. It is also stated that incomplete combustion of natural gas also produces carbon monoxide.
By burning natural gas in a combustion engine, you get mechanical energy.
All types of combustions are oxidation reactions.
Natural gas is not just one type of hyrdocarbon, and so its heat of combustion (or enthalpy of combustion) will vary from sources. However, it is primarily formed from methane which has a "heat of combustion" of 889 Kilojoules per mole, you could use that value. Hope that's what you wanted!
Natural gas is mainly composed of methane. When methane undergoes combustion, it produces water and CO2 . CH4 + 2O2 -------> CO2 + 2H2O

C2H6 is ethane. It's one of the constituents of natural gas.
