The cofficient of the [tex]\rm H_2S,HNO_3,NO,H_2O,S[/tex] willl be 3,2,2,4 and 3 respectively.
One or more compounds, known as reactants, are transformed into one or more distinct substances, known as products. Such a process is known as a chemical reaction.
The overall reaction is found as;
[tex]\rm H_2S +HNO_3 \rightarrow S+NO+H_2O[/tex]
Reduction reaction;
[tex]\rm N^{+5} + 3e^{-1} \rightarrow N^{+2}[/tex]
The oxidation half-reaction from the overall reaction is;
[tex]\rm S^{-2} = S+ 2e^{-1}[/tex]
Multiply the oxidation reaction by 2 and the reduction reaction by 3 and add them.
[tex]\rm 2 N^{+5}+6e^{-1}+3S^{-2} \rightarrow 2N^{+2}+3S+H_2O \\\\ 2N^{+5}+3 S^{-2}\rightarrow 2N^{+2}+3S \\\\ 3H_2S +2HNO_3 \rightarrow 3 S + 2NO + 4H_2O[/tex]
The cofficient of the [tex]\rm H_2S,HNO_3,NO,H_2O,S[/tex] willl be 3,2,2,4 and 3 respectively.
