the element is copper
the black coloured substance is cuo
2cu+o2=2cuo
cuo+h2=cu+h2o

Hii friend,
The shiny brown coloured element which belongs to atomic number 29 is "Copper".
Copper on reacts with air forms " cupric oxide" (cuo)
2Cu +O2 -> 2CuO (black)
Cu o on treating with hydrogen forms the element copper and water.
CuO + H2 -> Cu +H2O.
Hope this helps you a little!!!!
