the cross-section is strongly dependent on the neutron energy. In the common case, the cross-section is usually much larger at low energies than at high energies. This is why most nuclear reactors use a neutron moderator to reduce the neutron’s energy and thus increase the...
What is Nitrogen? The lack of reactivity of nitrogen is its biggest quality and as a result, the gas is used to prevent slow and fast oxidation. The electronics industry presents a perfect example of this use, as during the production of circuit boards and other small components, slow ...
reacts rapidly with water, snow, and ice to produce sodium hydroxide. when metallic sodium is exposed to air, it loses its silver appearance and develops an opaque grey colour layer which is a coating of sodium oxide. sodium does not react with nitrogen even at very high temperatures but ...
condensation is when a gas turns to a liquid. condensations have been defined to include those reactions in which two molecules are joined with loss of water. condensation is defined as the removal of heat from a system in such a manner that vapour is converted into liquid. in the summer,...
The sum of an atom's protons and neutrons is itsHow many neutrons are found in an isotope of Carbon-14?a) What are electron shells? b) How many electrons are in each? c) How does the number of electrons in a shell affect the reactivity of an atom?
Our calculations, however, show that at the HF/6-31G* level, the carbon atom is coplanar with the nitrogens while the oxygens of the nitro groups are rotated out of plane. The result is a structure with D3D3 symmetry. The C(CN)3−C(CN)3− anion is likewise found ...
Therefore, it seems that strain CCDM 368, through its membrane potential, reacts to the antibiotic presence in the environment and/or adapts to the environment to survive. It is worth emphasizing that experiments based on the stimulation of eukaryotic cells with bacteria are often performed in ...
What is a pulmonary surfactant? What are blood flukes? What is hypoxic hypoxia? What is erythrocyte protoporphyrin? What is placental cotyledon? What is autologous platelet gel? What is platelet reactivity? What type of macromolecule is gelatin?
Due to their non-reactivity, Inert Gases are used in preserving historical documents. 12 Noble Gases Noble Gases are known for their lack of color, odor, and flavor. Radon, one of the Noble Gases, is radioactive and can be found in some basements. 9 Inert Gases Inert Gases are often ...
