Question

Складіть рівняння реакцій: а) S + О2 → б) Н2S + О2 → в) Fe + О2 → Врахуйте, що валентність у Сульфуру буде (IV), а у Феруму – (ІІІ) СРОЧНО !!!!​

Answer 1

Ответ:

SO2 ( валентність S- 4 , валентність О- 2тому маємо SO2) ;

FeO2( валентність феруму 3 тому Fe2O3)

Answer 2

Equation for Reaction a):

The equation for the reaction between sulfur (S) and oxygen (O2) can be written as:

S + O2 → SO2

In this reaction, sulfur combines with oxygen to form sulfur dioxide.

Equation for Reaction б):

The equation for the reaction between hydrogen sulfide (H2S) and oxygen (O2) can be written as:

2H2S + 3O2 → 2H2O + 2SO2

In this reaction, hydrogen sulfide reacts with oxygen to produce water and sulfur dioxide.

Equation for Reaction в):

The equation for the reaction between iron (Fe) and oxygen (O2) can be written as:

4Fe + 3O2 → 2Fe2O3

In this reaction, iron reacts with oxygen to form iron(III) oxide.

Please note that the valence of sulfur in reaction a) is IV, and the valence of iron in reaction в) is III.
