Consider the unbalanced chemical reaction shown below: Cu(s)+HNO3(aq)→Cu(NO3)2(aq)+NO(g)+H2O(l) The oxidation state of Cu in Cu(s)Cu(s) = The oxidation state of Cu in Cu(NO_3)_2(aq)Cu(NO3)2(aq) = The oxidation state of N in HNO_3(aq)HNO3(aq) = The oxidation state of N in NO(g)NO(g) = The total number of electrons transferred in this reaction is = The sum of the coefficients in the balanced chemical reaction =
I think I may have also done some of the oxidation states wrong.
Please let me know the oxidation states and if it is oxidation or
reduction. Thank you!
