Question

does sodium carbonate decahydrate and ammonium dichromate both
swell up on heating​

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.
