Consider this reaction: h2s hno3 right arrow. s no h2o reduction half-reaction: n 5 3e- right arrow. n 2 oxidation half-reaction
Vera_Pavlovna [14]

The coefficients of H2S and HNO3 in the balanced reaction equation are 2 and 3 respectively.

<h3>Chemical reaction</h3>

In a chemical reaction, reactans interact in a unique way to form products. In this case, the unbalanced reaction equation is; H2S + HNO3-----> NO + H2O.

Since this reaction is redox and electrons are lost/gained in the process, the coefficients of H2S and HNO3 in the balanced reaction equation are 2 and 3 respectively.
