Sentences with phrase «fewer hydrogen atoms»

They differ from saturated fats by having fewer hydrogen atoms bonded to their carbon chains.

Gravity will ultimately determine the fate of the expansion, and gravity is dependent upon the mass of the universe; specifically, there is a critical density of mass in the universe of 10 - 29 g / cm3 (equivalent to a few hydrogen atoms in a phone booth) that determines what might happen.

«The large - scale differences in the structures and transmission characteristics of these proteins — caused by what amounts to seemingly insignificant differences in the positions of a few carbon and hydrogen atoms — are quite remarkable,» Jaroniec said.

Of the nuclei, most are single protons - the nuclei of hydrogen atoms - but a few are much heavier, ranging up to the nuclei of lead atoms.

«Such galaxies, which have remained dormant for most of their lives, are believed to contain the chemical elements forged a few minutes after the Big Bang.By measuring the relative number of hydrogen and helium atoms in the Little Cub we might be able to learn more about what made up the Universe in the moments after it began 13.7 billion years ago,» Cooke added.

Like good gardeners, the team trimmed a few pendant amines off their catalyst, leaving only enough to make the protons stand out, ready to accept a negatively charged hydrogen atom.

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 damaged.
