Sodium nitrate Sodium nitrate is a white crystalline solid. Noncombustible but accelerates the burning of combustible materials. If large quantities are involved in fire or the combustible material is finely divided an explosion may result. May explode under prolonged exposure to heat or fire. Toxic oxides of nitrogen are produced in fires. Used in solid propellants, explosives, fertilizers, and for many other uses.

Toxic Substances Portal - n-Hexane n-Hexane (hereafter referred to simply as hexane) is a chemical made from crude oil. Pure hexane is a colorless liquid with a slightly disagreeable odor. It evaporates very easily into the air and dissolves only slightly in water. Hexane is highly flammable, and its vapors can be explosive. Pure hexane is used in laboratories.

Nitrogen Nitrogen is a nonmetal, with an electronegativity of 3.04. It has five electrons in its outer shell and is, therefore, trivalent in most compounds. The triple bond in molecular nitrogen (N 2) is one of the strongest.itrogen gas has become the inert gas of choice for inert gas asphyxiation, and is under consideration as a replacement for lethal injection in Oklahoma. Nitrogen is promoted by euthanasia advocate Philip Nitschke to end life in a peaceful, reliable [and] totally legal manner.

Neurofibromatosis Neurofibromatosis (NF) is a group of three conditions in which tumors grow in the nervous system. The three types are neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2), and schwannomatosis. In NF1 symptoms include light brown spots on the skin, freckles in the armpit and groin, small bumps within nerves, and scoliosis.

Alone we are rare. Together we are strong.â¥ Donate Today General Discussion. Necrotizing fasciitis (NF) is a rare infection that means decaying infection of the fascia, which is the soft tissue that is part of the connective tissue system that runs throughout the body. NF is caused by one or more bacteria that attacks the skin, the tissue just beneath the skin (subcutaneous tissue), and the fascia causing these tissues to die (necrosis).

- Nitrogen oxides are a group of gases that are composed of nitrogen and oxygen. Two of the most common nitrogen oxides are nitric oxide and nitrogen dioxide. The chemical formula for nitric oxide is NO; for nitrogen dioxide, it is NO2. Nitrous oxide, N2O, is a greenhouse gas that contributes to climate change.itric oxide is used to bleach rayon and produce nitric acid. Nitrogen dioxide is used to produce rocket fuels, explosives, and other chemicals. Nitrogen dioxide is sometimes used to bleach flour. Nitrogen oxides are common pollutants found in most of the air in the United States.

Chlorofluorocarbon Chlorofluorocarbons (CFC) are gases used for various purposes including solvents,refrigerants and aerosol sprays. They are organic chemicals and contain carbon, (sometimes hydrogen,) chlorine, and fluorine. They were much used in the middle 20th century, replacing chemicals that were toxic or flammable or had other problems. In 1978, Sweden became the first country that banned CFC products.
