Question

2H2S+3O2=2H2O+2SO2 тип реакции?

Answer 1

Окислительно-восстановительная реакция :

H2S(-2)+O2(0)=H2O+S(+4)O(-2)2

S(-2)-6e-=S(+4)
2 - восстановитель, процесс окисления

2O(0)+4e-=2O(-2)
3 окислитель, процесс восстановления

2S(-2)+6O(0)=2S(+4)+6O(-2)
2H2S+3O2=2H2O+2SO2

Answer 2

Окислитеьно-восстановительная 
сложение 

Answer 3

Reaction Type and Balanced Equation

The given chemical equation is:

2H2S + 3O2 = 2H2O + 2SO2

This is a combustion reaction. In a combustion reaction, a substance reacts with oxygen to produce heat and light. In this case, hydrogen sulfide (H2S) reacts with oxygen (O2) to produce water (H2O) and sulfur dioxide (SO2).

To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here is the balanced equation:

2H2S + 3O2 = 2H2O + 2SO2

Please note that the equation is already balanced.

Summary

The reaction is a combustion reaction, and the balanced equation is:

2H2S + 3O2 = 2H2O + 2SO2
