Question

расставить методом электронного баланса1) SO2+H2S=S+H2O2) SO2+H2O+I2=HI+H2SO4

Answer 1

SO2+2H2S=3S+2H2O
S(+4)  +4e= S(0)
S(-2)+2e=S(0)

SO2+2H2O+I2=2HI+H2SO4
I2(0)+2e=2I(-1)
S(+4)-2e=S(+6)

Answer 2

Reaction 1: SO2 + H2S = S + H2O

The given chemical equation is:

SO2 + H2S = S + H2O

This equation represents a reaction between sulfur dioxide (SO2) and hydrogen sulfide (H2S) to produce elemental sulfur (S) and water (H2O).

To balance this equation using the method of electronic balancing, we need to ensure that the number of atoms of each element is the same
