Question

:HNO3(aq)+ Cu(s)->NO2(g)+ Cu(NO3)2(aq)+ H2O(l)




Balance using ion electron method

Answer 1

Answer:

Explanation:

For the reaction:HNO3(aq)+ Cu(s)->NO2(g)+ Cu(NO3)2(aq)+ H2O(l). 2*the reducing half reaction plus 1*the oxidizing half reaction cancels the electrons: 2H+(aq) + 2HNO3(aq) + Cu(s) + 2NO3-(aq) -> 2NO2(g) + 2H2O(l) + Cu(NO3)2(aq).
