Which of the following ammonium salt is used for making artificial volcano ?

Options:

Answer:

Solution:

The ammonium salt used for making an artificial volcano is ammonium dichromate, $(NH_{4})_{2} Cr_{2} O_{7}$ . When heated, it decomposes exothermically to produce green chromium(III) oxide, nitrogen gas, and water vapor, creating a visually striking "volcano" effect.

The decomposition reaction is:

$(NH_{4})_{2} Cr_{2} O_{7} (s) Δ Cr_{2} O_{3} (s) + N_{2} (g) + 4 H_{2} O (g)$
