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.
Best Answer: The stock name for this compound is ammonium phosphate. This is an ionic compound, which means that it is named with the names of the ions. The cation (the first ion, positively charged) is NH4+, which is called ammonium. The anion (the second ion, negatively charged) is called phosphate, PO4(3-).Note that because the entire compound must be neutral, there are three ammonium (+) ions to balance out one 3- PO4 ion.Source(s):he cation (the first ion, positively charged) is NH4+, which is called ammonium. The anion (the second ion, negatively charged) is called phosphate, PO4(3-).
