such as hydrogen sulfide, which make farts smell bad. However, bad smells only apply to about 1 percent of the gas that people expel, most of which is almost odor-free.
Where Does Helium Come from? Hydrogen and helium are the two most abundant elements in the Universe. As a matter of fact, the entire cosmic inventory of hydrogen and helium make up over 98聽% of all known matter in the Universe. The remaining 2聽% amounts to every o... WM“S Jr -...

"Jupiter is calleda failed starbecause it is made of the same elements (hydrogen and helium) as is the Sun, but it is not massive enough to have the internal pressure and temperature necessary to cause hydrogen to fuse to helium, the energy source that powers the sun and most other stars...
They are unique because their structures, characterized by polymer chains, are linked through powerful hydrogen bonds that efficiently transfer mechanical stress. These characteristics make aramids perfectly suited to various industries like automotive, aerospace and defense, where heat resistance and ...
The chemicals used to make nylon are amine, hexamethylene diamine, and adipic acid. The new amide molecules are held together by hydrogen atoms. This chain of molecules, which is nylon, closely resembles the chemical structure of silk, which is produced by silkworms. ...
7.Some of the warm-adapted bacteria actively carry out chemical synthesis, but unlike photosynthetic organisms, they do not use light as an energy source. Other kinds of bacteria get energy by combining hydrogen or sulfur with oxygen in the way that higher organisms obtain energy by oxidizing su...
(in accordance with the national hydrogen strategy [11]), other PtX solutions, or, where feasible, costly direct electrification solutions. In this context, it should be noted that the national biomass potential is limited and its use must be sustainable without leading to further biodiversity ...
It was also demonstrated, as early as in 1960 that the surfaces of silica have peroxidative activity where this activity was shown to be increased with the presence of trace amounts of iron and further increased with the addition of hydrogen peroxide. It was then speculated that a substance ...
