The dissolution of copper sulfide in aqueous nitric acid is described by thefollowing
Chapter 4, Problem 27(choose chapter or problem)
The dissolution of copper sulfide in aqueous nitric acid is described by thefollowing chemical equation:- + 2+ 2-aCuS + bN03 + cH -7 dCu + eS04 +f NO + gH20where the coefficients a, b, c, d, e,J, and g are the numbers of the various moleculeparticipating in the reaction and are unknown. The unknown coefficientsare determined by balancing each atom on left and right and thenbalancing the ionic charge. The resulting equations are:a= d, a= e , b =f, 3b = 4e+f+g , c = 2g, -b +c = 2d-2e
