Web#NEET2024 On tribromooctaoxide question came in NEET 2024 WebIt has oxidation number −2. Four oxygen atoms are attached to Cr atom through a single bond. Each of these oxygen has an oxidation number −1. Let x be the oxidation number of chromium. The sum of all the oxidation numbers is zero. Hence, x−2+4(−1)=0 and x=6 . Thus, the oxidation number of chromium in CrO 5 is +6 . flushing hospital address queens nyc

WebFormula in Hill system is Br3O8: Computing molar mass (molar weight) To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In chemical formula … Web21 de set. de 2014 · Since 3 oxygen hence total -6 for all 3 oxygen and +6 for Br bonded to terminal Oxygen. Similarly +4 for central Br. When covalent bond is form between same atoms then both the atoms acquire the oxidation state of zero. So their is no change in oxidation state of Br by Br-Br covalent bond. Oxidation state of Br at terminal positions … flushing hospital billing department
