Question

Write an equation for the following conversions A, B, C and D.

Answer 1

A: Copper can be converted into copper nitrate.

\[\ce{Cu + 4HNO3 -> \underset{Copper nitrate}{Cu(NO3)2} + 2H2O + 2NO2}\]

B: \[\ce{\underset{Blue crystalline}{2Cu(NO3)2} ->[\Delta] \underset{Black}{2CuO} + 4NO2 + O2}\]

C: \[\ce{\underset{Strong heating}{2Cu + O2} ->[\Delta] \underset{Black}{2CuO}}\]

D: By reduction,

\[\ce{CuO + H2 ->[\Delta] Cu + H2O}\]
