Question

Write the balanced equation for the following:
(a) Action of concentrated nitric acid on copper.
(b) Action of heat on AgNO₃.

Answer 1

(a) $3\mathrm{Cu}+8{\mathrm{HNO}}_3\to 3\mathrm{Cu}{\left({\mathrm{NO}}_3\right)}_2+2{\mathrm{NO}}_2+4{\mathrm{H}}_2\mathrm{O}$
(b) $2{\mathrm{AgNO}}_3\stackrel{∆}{\to }2\mathrm{Ag}+2{\mathrm{NO}}_2+{\mathrm{O}}_2$
