Write an equation to illustrate the reducing nature of ammonia.
As a reducing agent, NH3 reduces heated CuO, while it is itself oxidized to water and nitrogen.
The equation is:-
3CuO(s) + 2NH3(g) → 3Cu(s) + 3H2O(l) + N2(g)
Give two examples to show the reducing property of hydrogen. Illustrate using equations.
