1.	Ammonium dichromate upon heating decomposes to give nitrogen gas and chromium oxide is it a redox reaction ? If so what is the type of the redox whether inter or introamolecular
Answer» Solution :Hre O.N of N increase from -3 to 0 in `N_(2)` THEREFORE it is oxidised in contrast the O.N of Cr DECREASE from +6 to +3 in `Cr_(2)O_(3)` therefore it is reduced thus it is an interamolecular REDOX reaction SINCE both the SPECIES cation and the anion are part of the same compountd ammonium dichromate
