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