A. a) Vanadium nitrate is usually Vandium (III) nitrate = V(NO3)3 b) Calcium bisulfate is called Calcium hydrogen sulfate = Ca(HSO4)2 c) Aurous nitride often called Gold (I) nitride = Au3N d) Cyanic acid is only stable below 0 C = CNOH. At higher temperatures, it polymerizes (usually into a trimer) = (CNOH)3 e) Ferrous ferrocyanide or Iron (II) ferrocyanide = Fe2[Fe(CN)6]

Write the chemical formula!! HELP?
Q. Write the chemical formula for each of the given traditional names: 11. stannic carbonate 12. cuprous oxalate 13. plumbous sulphate 14. aurous sulphide 15. ferrous hydroxide Write the traditional AND/OR Stock System name for each of the following compounds. 1. FeS 2. SnCO3 3. Ni2O2 4. CuCl2 5. PbSO4
Asked by freindly asian - Sat Dec 2 18:55:49 2006 - - 3 Answers - 0 Comments
A. OK all the chemical symbols on the periodic table relate to the old names. Iron (Fe) is Ferrous, so Ferrous hydroxide is Iron hydroxide. Aurous is gold (Au), Cuprous (Cu) is copper, plumbus (Pb) is lead, Stannic (Sn) is tin. Carbonate is CO3, hydroxide OH, sulphate SO4, Sulphide S (2-), an oxalate ion is (COO)2, can be written as C2O4 it's charge is 2-. You should be able to work them all out now. Good luck.
