    The salt X is likely ammonium dichromate, (NH4)2Cr2O7, which is orange, but it turns green when it decomposes. When heated, it undergoes a decomposition reaction to produce chromium(III) oxide (Cr2O3), nitrogen gas (N2), and water vapor (H2O). The green-colored substance is chromium(III) oxide, and the gas with a pungent smell is nitrogen dioxide (NO2) which is usually formed due to secondary reactions. The decomposition reaction of ammonium dichromate can be represented by the following chemical equation: (NH4)2Cr2O7→Cr2O3+N2+4H2O
    During the heating process, some NH3 may be released, which can further oxidize to NO2 in the presence of heat and oxygen. So, the salt X is ammonium dichromate, (NH4)2Cr2O7, and the gas Y is nitrogen dioxide, NO2. Here is the full balanced chemical equation: (NH4)2Cr2O7→Cr2O3+N2+4H2O
    When considering secondary reactions for the release of NO2: 4NH3+7O2→4NO2+6H2O
