Sentences with phrase «produces oxygen atoms»

In its stratosphere I conclude the important photodissociation reaction that of carbon dioxide with ultraviolet photons which produces oxygen atoms and carbon monoxide molecules.

For the important ultraviolet photons which are desired to be removed from the solar radiation are those less energetic photons which decompose the ozone molecules to produce another oxygen atom which again can reform another ozone molecule.

The first is to produce the oxygen atom from oxygen molecules.

Not exact matches

A value for Hoyle state 2 % higher than the measured value would prevent the formation of carbon.5 A value 2 % lower than the measured value would produce lots of carbon, but no oxygen.5 Both are essential atoms for life.

There are basically two types of lines, those produced by collisions between the atoms or ions and the electrons in the surrounding gas, which are called collision lines, and which are very bright for elements such as oxygen, nitrogen and neon, and lines which are produced when ions capture free electrons, which are called recombination lines, and which are bright only for those gases with the highest abundances in the interstellar medium: hydrogen and helium.

Other elements — typically oxygen, nitrogen, and hydrogen — frequently join that carbon spine, and the choice and arrangement of those atoms produces specific varieties of polymers.

The first mechanism suggests hydrogen (H) atoms each associate with only oxygen (O) atoms to produce only OH species on the surface.

The highly reactive radical, Cl •, then abstracts a hydrogen atom of CH4 to give methyl radicals, CH3 •, which in turn react with oxygen to produce valuable methanol and formic acid.

Combustion causes almost every atom of carbon in the fuel to combine with two atoms of oxygen, producing carbon dioxide.

Normally, one metal atom (either barium or calcium) can react with an oxygen atom to produce a stable molecule.

The surprise to biochemists was that the enzyme, called FtmOx1, produces a highly reactive «helper» known as a free radical that assists in putting the oxygen atoms in the right place.

In the new paper, the researchers map out how an enzyme in a common mold species called Aspergillus fumigatus adds a pair of oxygen atoms to a toxin the mold produces.

Substrate molecules, such as organic compounds containing double bonds, can extract oxygen atoms from this bank to produce oxidized products.

«The nickel fragments that sputter off of the pellet react with the oxygen atoms to produce an oxidized form of nickel that gets deposited onto the semiconductor,» Lewis says.

Some of these recombine into nitric oxide, and this in turn reacts with other atmospheric chemicals, occasionally producing a molecule made up of three oxygen atoms — ozone, or O3.

Some of these light - element nuclei also might be produced by cosmic rays shattering atoms of carbon, nitrogen, oxygen, and other elements in the interstellar medium.

Scientists had suspected that the atoms in carbon dioxide could be decoupled to produce oxygen gas, he notes.

The mass of CO2emitted, some 33 billion tonnes in 2011, is more than twice the mass of all of the fossil fuel produced in that year, a little under 15 billion tonnes (we have to sequester two atoms of oxygen with every atom of carbon).

The resultant attachment of single oxygen atoms to O2 produces ozone (O3).

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.

However, my main point was not so much about the «make up» of ozone but more about the possibility that as long as oxygen atoms and molecules absorb enough energy from UV radiation to alter their structure it may be that they also produce an increase in their heat content, which should be greater at any points nearest to the source — i.e..
