But many molecules have more than two atoms — carbon dioxide, for instance, is triatomic, consisting of a carbon molecule linked to two oxygen molecules — one on each arm, as it were.

When petroleum is burned, some energy is required to separate the molecules into individual atoms, but much more energy is given back as the carbon and hydrogen atoms combine with oxygen to give carbon dioxide and water vapor.

As with petroleum, some energy is required to separate the molecule into separate atoms, but the energy is more than returned when the carbon and hydrogen burn to form carbon dioxide and water vapor respectively.

If so, then you either disagree with the theory of combustion, that is, one atom of carbon burned in an excess of oxygen produces one molecule of CO2, or you believe there is some sort of vast conspirousy to make people think that much more fossil fuel has been burned than actually has been.

Fossil Fuel is a generic term that isn't quite correct Natural Gasoline is a distilled derivative of oil but almost all ofit is manufactured from cracked and recombined oil derivativeswhile natural gasoline is further refined intoPropane, butane, Proproline (a plastics feed stock), and Natural gasand also separates out sulfur (for fertilizer and explosives) Gasoline can be made from coal («Coaline») or from organic matter («Bio-fuel») but uses a few of oil based feed stocks instead tomake «Sythiline» (artificial gasoline) This gasoline is actually cleaner burning then natural gas with allit's «flare offs» (butane, propane, propoline, sulfur) used in theearly 19th century because it is manufactured only with essentialHydrocarbons Diesel fuel is also becoming more and more Manufactured instead ofdistilled as demand for it rises but improvements in Hydro cleaningis allowing for diesel with no volatile chemicals like sulfur andmercury (taken out for petro - chemical feedstock to make fertilizerand thermometers) In both cases what you have is pure hydro - carbons, a carbon atomwith hydrogen atoms attached to it In the case of gasoline there is CH1, cH7, CH11 When in a combustion engine the gasoline is sprayed into the pistonafter being mixed with air and the drive of the engine compressesthe the chamber filled with the gasoline mist until it's full downstoke then the spark plug causes the Exothermic reaction... which isthe conversion of the potential energy in the gasoline mist to heatand force, with the force side of that equation shooting the pistonupward and the top of the stroke kicking what's left of thecaramelized gasoline mist out into the Emission control box If the Emulsion control box wasn't there to filter out the burntgasoline particles, any potential additives and volatile chemicalsthen the caramelized gunk hitting air would create CARBON MONOXIDEin the cooler then the heat of the engine difference CARBON MONOXIDE can also become a problem if the Emissions controlBox filter, air filters or muffler filters is worn or dacarbon atomwith hydrogen atoms attached to it In the case of gasoline there is CH1, cH7, CH11 When in a combustion engine the gasoline is sprayed into the pistonafter being mixed with air and the drive of the engine compressesthe the chamber filled with the gasoline mist until it's full downstoke then the spark plug causes the Exothermic reaction... which isthe conversion of the potential energy in the gasoline mist to heatand force, with the force side of that equation shooting the pistonupward and the top of the stroke kicking what's left of thecaramelized gasoline mist out into the Emission control box If the Emulsion control box wasn't there to filter out the burntgasoline particles, any potential additives and volatile chemicalsthen the caramelized gunk hitting air would create CARBON MONOXIDEin the cooler then the heat of the engine difference CARBON MONOXIDE can also become a problem if the Emissions controlBox filter, air filters or muffler filters is worn or daCARBON MONOXIDEin the cooler then the heat of the engine difference CARBON MONOXIDE can also become a problem if the Emissions controlBox filter, air filters or muffler filters is worn or daCARBON MONOXIDE can also become a problem if the Emissions controlBox filter, air filters or muffler filters is worn or damaged.
