${\mathrm{AgNO}}_3$ on heating strongly gives Ag metal. $2{\mathrm{AgNO}}_3\stackrel{\text{ Redheat }}{\to }2\mathrm{Ag}+2{\mathrm{NO}}_2+{\mathrm{O}}_2$

While others give oxides of the metals

$$\begin{array}{rlrl}& 2\mathrm{Pb}{\left({\mathrm{NO}}_3\right)}_2\stackrel{\Delta }{\to }2\mathrm{PbO}+4{\mathrm{NO}}_2+{\mathrm{O}}_2& & \end{array}$$

$$2\mathrm{Cu}{\left({\mathrm{NO}}_3\right)}_2\stackrel{\Delta }{\to }2\mathrm{CuO}+4{\mathrm{NO}}_2+{\mathrm{O}}_2$$

$$4\mathrm{Al}{\left({\mathrm{NO}}_3\right)}_3\stackrel{\Delta }{\to }2{\mathrm{Al}}_2{\mathrm{O}}_3+12{\mathrm{NO}}_2+3{\mathrm{O}}_2$$
