Question

An orange coloured ammonium salt (A) when heated in a test tube swells up

to form a green solid (B) and a neutral gas (C) along with steamy vapours.​

Answer 1

Answer:

Ammonium dichromate decomposes on heating to produce nitrogen gas, water vapor (gaseous due to the temperature of the reaction), and solid chromium(III) oxide. The skeletal net reaction is shown below, unbalanced, along with the molecular weights of the compounds involved in the decomposition.
