How do we represent the oxidation of hydrogen sulfide by nitric acid to give sulfur and #NO(g)#?
This is a redox reaction: sulfur is oxidized, and nitrogen is reduced.
In both cases, mass is balanced, and charge is balanced, as is required for a chemical reaction.
For the overall redox reaction, we simply cross-multiply each equation in order to eliminate the electrons that appear in each half equation:
Are charge and mass balanced here? What would be observed in this reaction is the appearance of a fine white precipitate of sulfur. The evolved
You are certainly free to multiply each stoichiometric coefficient by
