Question

Складіть рівняння реакцій за якими можна виконати перетворення 1. H2O2 => O2 => P2O5 => H3PO4 2.KMnO4 => O2 => H2O => NaOH Якщо не складно то поясніть як його робити

Answer 1

2H2O2 -> 2H2O + O2

4O2 + P4 -> 2P2O5

P2O5 + 3H2O -> 2H3PO4

2KMnO4 -> 2KOH + 5O2 + 3MnO2

5O2 + 2H2O -> 4H+ + 4OH-

4OH- + 4H+ -> 4H2O

2NaOH + H2O -> Na2O + 2H2O

Answer 2

Equations for the Given Transformations

1. The equation for the transformation from H2O2 to H3PO4 can be represented as follows: ``` H2O2 -> O2 -> P2O5 -> H3PO4 ```

2. The equation for the transformation from KMnO4 to NaOH can be represented as follows: ``` KMnO4 -> O2 -> H2O -> NaOH ```

Explanation of the Transformations

1. Transformation from H2O2 to H3PO4: - In the first step, hydrogen peroxide (H2O2) decomposes into oxygen gas (O2). - The equation for this decomposition reaction is: 2H2O2 -> 2H2O + O2. - This reaction is typically catalyzed by a catalyst such as manganese dioxide (MnO2). - In the second step, the oxygen gas (O2) reacts with phosphorus pentoxide (P2O5) to form phosphoric acid (H3PO4). - The equation for this reaction is: O2 + P2O5 -> 2H3PO4.

2. Transformation from KMnO4 to NaOH: - In the first step, potassium permanganate (KMnO4) decomposes into oxygen gas (O2). - The equation for this decomposition reaction is: 2KMnO4 -> K2O + 2MnO2 + 3O2. - In the second step, the oxygen gas (O2) reacts with water (H2O) to form water vapor (H2O). - The equation for this reaction is: O2 + 2H2O -> 2H2O. - In the third step, the water vapor (H2O) reacts with sodium hydroxide (NaOH) to form sodium hydroxide solution. - The equation for this reaction is: H2O + NaOH -> NaOH.

Please note that these equations are simplified representations of the transformations and may not include all the intermediate steps or conditions required for the reactions to occur.
