Firstly you have not completed your second question but don't worry I know-
When hydrogen gas is passed through heated copper oxide reduction of copper oxide happens . The equation is-
CuO +H2= Cu + H2O
Some current will induced in coil B . It is because of the change in the magnetic field lines of coil A because of change of current.
