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.
Penta= 5. Octa = 8. So pentachlorine octaoxide is Cl5O8
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.
The chemical formula for tetranitrogen decasulfide is N4S10.
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.
The chemical formula for dinitrogen pentoxide is N2O5.
Penta= 5. Octa = 8. So pentachlorine octaoxide is Cl5O8
The formula for Heptasulfur Dioxide is S7O2.
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.
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.
The chemical formula for tetranitrogen decasulfide is N4S10.
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
Iit is phosphorus penta fluoride a molecule with Trigonal bipyramidal geometry.
