The flow of blood to the arteries of the body is impaired when aortic stenosis exists. Ultimately, this can lead to heart failure. Aortic stenosis occurs three times more commonly in men than women. Picture of heart and valves -- aortic valve stenosis.
Ammonium thiocyanate is colorless lustrous monoclinic flaky or columnar crystal with the chemical formula being NH4SCN and the molecular weight of 76.12. At 92 â, it is rhombohedral crystal with the melting point of 147 â (decompose at 170 â), the relative density of 1.3057 and the refractive index of 1.685.
Ammonium nitrate (AN) is an odorless, colorless or white, crystal salt produced by the reaction of ammonia and nitric acid. It was the first solid nitrogen (N) fertilizer produced on a large scale.ertilizer prills are formed as drops of the concentrated ammonium nitrate solution (95 to 99 percent) fall from a tower and solidify. Low-density prills are more porous and are preferred for industrial or explosive use.
