PFl5
BrI5 Br is Bromine and is being listed as a +5 ion and Penta means five so it is I5 so the answer is BrI5.
dinitrogen pentaoxide: This IS the formula name for the chemical formula N2O5, sometimes called nitrogen pentoxide (without 'di' and pent without 'a').From Latin: 'di' = two and 'penta' = five
PCl3 is the formula. This is the compound we know as phosphorus trichloride.
This compound very probable doesn't exist; PCl3 is the chemical formula of phosphorus trichloride.
Penta= 5. Octa = 8. So pentachlorine octaoxide is Cl5O8
This formula could be written in more than one way, but one way is: F3CSF5.
BrI5 Br is Bromine and is being listed as a +5 ion and Penta means five so it is I5 so the answer is BrI5.
N2O5 ( di=2, penta=5)
The formula for Heptasulfur Dioxide is S7O2.
why dose not nitrogen from penta-halides like phosphorus
The molecular formula for iodine pentafluoride is IF5. No prefix in front of iodine is understood to be one, but mono- is not used for the first element in a binary covalent compount. The prefix penta- means five, so the subscript for fluoride is 5. Unfortunately, there is no way to write the 5 as a subscript.
Iit is phosphorus penta fluoride a molecule with Trigonal bipyramidal geometry.
dinitrogen pentaoxide: This IS the formula name for the chemical formula N2O5, sometimes called nitrogen pentoxide (without 'di' and pent without 'a').From Latin: 'di' = two and 'penta' = five
The chemical formula is CuSO4.5 H2O; the pentahydrate contain 5 molecules of water (penta = five, in the Greek lanuage).
PCl3 is the formula. This is the compound we know as phosphorus trichloride.
P2S5 is Phosphorous Penta Sulphide. P = Phosphours S = Sulfur Its molecular weight is 222.28.
V+4 PO4-3 <--- these are the ions and their charges V+4 V+4 V+4 PO4-3 PO4-3 PO4-3 PO4-3 <--- the charges have to add up to zero, so three +4 vanadium ions cancels out four -3 phosphate ions V3(PO4)4 <--- simplify
