Question

How is heating of sugar different from heating of ammonium chloride? Explain.
(HINT- Amm.Chl. sublimes on heating)

Answer 1

Heating of sugar is a compound change-As the sugar twists on heating (Loses its properties, change in synthesis).

Sugar (On heating)→ New compound

Heating of Ammonium chloride is a physical change-It just changes its state yet piece stays same.

Ammonium chloride (Solid) (On heating)→ Ammonium chloride (Gas)

At the point when sugar is heated, it melts and afterward caramelizes emitting the water. After this, it turns black(carbon) and after that converts to CO2.

So heating of sugar is an endothermic, deterioration and oxidation response.

At the point when Ammonium chloride (NH4Cl) is heated, it specifically goes from strong state to vapor state without changing in the vapor. So the warming of NH4Cl is a case of sublimation response.

Answer 2

When sugar is heated, it does not vapourize instead it becomes brownish and then later it becomes black but when ammonium chloride is heated chlorine gas is released
