Write a balanced equation for the oxidation of copper metal by nitric acid.
A) Cu(s) + 6H+(aq) + NO3−(aq) → Cu2+(aq) + NH3(aq) + 3H2O(l)
B) Cu(s) + 12H+(aq) + 2NO3−(aq) → Cu2+(aq) + N2(g) + 6H2O(l)
C) 3Cu(s) + 8H+(aq) + 2NO3−(aq) → 3Cu2+(aq) + 2NO(g) + 4H2O(l)
D) 4Cu(s) + 6H+(aq) + NO3−(aq) → 4Cu2+(aq) + NH3(aq) + 3H2O(l)
E) 5Cu(s) + 12H+(aq) + 2NO3−(aq) → 5Cu2+(aq) + N2(g) + 6H2O(l)
