(NH₄)₂Cr₂O₇(s) → Cr₂O₃(s) + N₂(g) + 4H₂O(g)
Here's a breakdown:
* (NH₄)₂Cr₂O₇(s): This is the formula for ammonium dichromate in its solid state (s).
* Cr₂O₃(s): This represents chromium(III) oxide, a solid green product.
* N₂(g): Nitrogen gas is produced in its gaseous state (g).
* 4H₂O(g): Four molecules of water vapor are released as a gas.
This reaction is a classic example of a dramatic chemical demonstration known as the "volcano reaction." The heat from the reaction causes the ammonium dichromate to decompose rapidly, producing a large amount of green chromium(III) oxide and a puff of nitrogen gas and steam.
