Every reaction becomes easy in context of finding oxidised and reduced species.. If we know how to find oxidation number…if you know.. Then this question will look easy to u coz in H2S oxidation state of sulphur is - 2 and when H2S - > S Oxidation no. Of only S is 0(coz this is the element not a compoound) We can clearly see that oxidation no. Of S is increasing from - 2 to 0 so sulphur is undergoing oxidation while in O2 - > H2O Oxidation no. Of oxygen is decreasing from - 2 to zero.. So it is undergoing reduction..
