Question

A few crystals of Ag No 3, are strongly
heated​

Answer 1

Explanation:

When AgNO3 is heated strongly, the products formed are NO2 and O2.

The reaction is as follows:

2AgNO3(l) ---Δ-->> 2Ag(s)+O2(g)+2NO2(g)

Answer 2

Answer:

2 AgNO3(l) → 2 Ag(s) + O2(g) + 2 NO2(g)

Explanation:

Silver nitrate decomposes when heated:

2 AgNO3(l) → 2 Ag(s) + O2(g) + 2 NO2(g)

Qualitatively, decomposition is negligible below the melting point, but becomes appreciable around 250 °C and fully decomposes at 440 °C.[10]

Most metal nitrates thermally decompose to the respective oxides, but silver oxide decomposes at a lower temperature than silver nitrate, so the decomposition of silver nitrate yields elemental silver instead.
