- Determine the oxidation state of sulfur in each of the following:(a) SO3(b) SO2(c) SO32−arrow_forwardK2Cr207 + 7H2C204 · 2H2O 2K[Cr(C204)2(H2O)2] · 2H2O + 6CO2 + 13H2O Is this is redox reaction? if so, what element is being oxidized? what is initial and final oxidation state?arrow_forwardGive the oxidation state of the metal for each of the following oxides of the first transition series. (Hint: Oxides of formula M3O4 are examples of mixed valence compounds in which the metal ion is present in more than oneoxidation state. It is possible to write these compound formulas in the equivalent format MO∙M2O3, to permit estimation of the metal’s two oxidation states.)(a) Sc2O3(b) TiO2(c) V2O5(d) CrO3(e) MnO2(f) Fe3O4(g) Co3O4(h) NiO(i) Cu2Oarrow_forward
