Question

Напишите уравнения химических реакций, с помощью которых можно осуществить превращенияа)S>S03>Na2SO4б)Fe(OH)2>FeO>Fe(NO3)2

Answer 1

а)S>S03>Na2SO4

1)S+О2=SO2

2)2SO2 + O2 = 2SO3

3)2NaOH+SO3=Na2SO4+H2O

 

 

б)Fe(OH)2>FeO>Fe(NO3)2

1)Fe(OH)2=FeO+H2O

2)FeO+2HNO3=Fe(NO3)2+H2O

Answer 2

Chemical Equations for the Given Reactions:

a) The chemical reactions to achieve the transformation from S to Na2SO4 can be represented as follows:

1. Sulfur to Sulfur Trioxide (S to SO3): - The balanced chemical equation for the conversion of sulfur to sulfur trioxide is: ``` 2S + 3O2 → 2SO3 ```

2. Sulfur Trioxide to Sodium Sulfate (SO3 to Na2SO4): - The balanced chemical equation for the reaction of sulfur trioxide with sodium hydroxide to form sodium sulfate is: ``` SO3 + 2NaOH → Na2SO4 + H2O ```

b) The chemical reactions to achieve the transformation from Fe(OH)2 to Fe(NO3)2 can be represented as follows:

1. Iron(II) Hydroxide to Iron(II) Oxide (Fe(OH)2 to FeO): - The balanced chemical equation for the decomposition of iron(II) hydroxide to form iron(II) oxide is: ``` 2Fe(OH)2 → Fe2O3 + 3H2O ```

2. Iron(II) Oxide to Iron(II) Nitrate (FeO to Fe(NO3)2): - The balanced chemical equation for the reaction of iron(II) oxide with nitric acid to form iron(II) nitrate is: ``` FeO + 2HNO3 → Fe(NO3)2 + H2O ```

These chemical equations represent the step-by-step transformations from the given initial substances to the desired products.
