Ammonium dichromate (NH4)2Cr2O7 decomposes when heated yielding green chromium(III) oxide, nitrogen and water vapor. It is a comproportionation reaction where Cr(+6) of Cr2O7(2-) gets reduced to Cr(+3) of Cr2O3 oxidising N(-3) of NH4(+) to N(0) of N2 gas. Also some H2O is released but it does not involve any REDOX process.
