Explanation / Answer

Step 1)

oxidation and reduction half

Oxidation half

H2S -- > S

Reduction half

HNO3 -- > NO

Step 2

Balancing . O are balanced by H2O and H are balanced by H+

H2O + H2S -- > S + H2O+ 2H+   

3 H+ HNO3 -- > NO + H2O + H2O

Step 3 charge and electron balancing

3 H2O + 3 H2S -- >6 e- + 3 S + 3 H2O+ 6H+   

6 H+ 2 HNO3 +6 e- -- >2 NO + 2H2O +2 H2O

------------------------------------------------------

3 H2S + 2 HNO3 -- > 3 S + 2 NO + 4 H2O

So the balanced reaction is :

3 H2S + 2 HNO3 -- > 3 S + 2 NO + 4 H2O
