An example which you might come across in the lab is chromium(VI) oxide peroxide, $\ce{CrO5}$. $\ce{CrO5}$ $\ce{Cr2O3}$ $\ce{Na2O2}$ $\ce{BaO2}$ I think peroxy oxygen is peroxide, am I right?. Correct option (b) H 2 S 2 O 8. x=10-2 ; no element have ox .no 10 . In this compound, the oxidation state of Chromium is +6. 1 Answer +1 vote . Rubber magnetic composites were prepared by incorporation of barium ferrite in constant amount—50 phr into acrylonitrile-butadiene rubber. By looking at the above structure, you must have observed that 4 of the O atoms attached, are combined by the peroxide linkage. B + 5. Let the O.N. no. The preparation of Ketones is done by the oxidation of secondary alcohols. When you first see this compound you'll think that the oxidation number of Cr is :- x+{2×-(5)}=0 ……(equation-1) … which comes to +10. MEDIUM.
