by adding sodium hydroxide solution

ANSWER WITH REASON

Answer 1

$\huge\bold{\textbf{\textsf{{\color{cyan}{Answer}}}}}$

Such as CuO+H2SO4→CuSO4+H2O, CuSO4+Fe→FeSO4+Cu/ electrowinning the CuS04 solution, also can get copper cathode.

Determine the formula of copper(II) oxide by reducing it using hydrogen or methane. Natural gas (mainly methane) can also be used as a reducing agent, but the reaction is much slower.
