Ammonium dichromate decomposes to form nitrogen, water vapor, and chromium(III) oxide.
An alcohol-soaked fuse is placed upon a small mound of ammonium dichromate and ignited. The orange ammonium dichromate decomposes to form nitrogen, water vapor, and fluffy greenish-black chromium(III) oxide.
Equation:
(NH4)2Cr2O7 —> N2 + 4H2O + Cr2O3
