Question

ОВР SO2 + H2S => S + H2O

Answer 1

Это изи

SO2 + 2H2S = 3S + 2H2O;

S(-2) - 2e = S(0)|2 восстановитель

S(+4)+4e = S(0)|1 окислитель

Answer 2

The chemical equation you provided is a reaction between sulfur dioxide (SO2) and hydrogen sulfide (H2S) to form sulfur (S) and water (H2O). The balanced chemical equation for this reaction is as follows:

SO2 + 2 H2S -> 3 S + 2 H2O

In this reaction, one molecule of sulfur dioxide (SO2) reacts with two molecules of hydrogen sulfide (H2S) to produce three molecules of sulfur (S) and two molecules of water (H2O).
