Ammonium dichromate, (NH4)2Cr2O7, decomposes when heated to produce chromium(III) oxide [Cr2O3], nitrogen gas, and water vapor:
(NH4)2Cr2O7(s) --> Cr2O3(s) + N2(g) + 4H2O(g)
While the ammonium dichromate decomposes, it gives off orange sparks and throws the green chromium(III) oxide crystals into the air, producing an effect that looks like a miniature volcanic eruption.
The chromium(III) oxide crystals that are produced are "fluffier" than the original ammonium dichromate crystals, and even though a lot of the mass of the starting materials escapes as vapor, the product looks like a larger amount of material.
when ammonium chloride is heated its particles get converted into gaseous state i.e vapours of ammonium chloride due to sublimation.
produce silver
since ammonium nitrate decomposes on heating so ammonium nitrate is covered with excess of calcium hydroxide with some water and then heated to get ammonia
If ammonium chloride and sand are heated or undergo sublimation, ammonium chloride being a sublimable substance sublimes and sand is left behind as the residue.
CaCO3 --> CO2 + CaO
Either ammonium nitrite or ammonium dichromate can he heated to obtain nitrogen gas.
nothing happens. it becomes an aqueous solution of ammonium chloride
It burns.
It forms soap.
2FeSo4--->Fe2O3+So2+So3
ammonia should release on heating.

The solvent is vaporized.
The particles in a liguid are bonded (not as strongly as a solid which is why it flows.) when it is heated the particles vibrate and eventually the bonds break and the particles break away. This is evaporation.
Ammonia gas will be evolved. The chemical reaction is :NH4Cl + NaOH --> NH3 (g) + NaCl + H2O
when natural gas is strongly heated, hydrogen(H) and carbon(C) are obtained.
