Question

В реакции, схема которой NO₂ + H₂O = HNO₃ + NO степень окисления Нитрогена изменилась, а Оксигена - нет степень окисления Гидрогена изменилась, а Оксигена - нет степень окисления Оксигена изменилась, а Нитрогена - нет степень окисления элементов не изменилась

Answer 1

изменилась степень окисления нитрогена, а оксигена-нет!

Answer 2

Changes in Oxidation States in the Reaction NO₂ + H₂O = HNO₃ + NO

In the given reaction, the oxidation state of nitrogen (N) changes, while the oxidation state of oxygen (O) remains the same. The oxidation state of hydrogen (H) also changes, but the question states that the oxidation state of oxygen does not change.

The reaction can be represented as follows: NO₂ + H₂O → HNO₃ + NO

Let's analyze the changes in oxidation states for each element involved:

1. Nitrogen (N): - In NO₂, the oxidation state of nitrogen is +4. - In HNO₃, the oxidation state of nitrogen is +5. - Therefore, the oxidation state of nitrogen increases from +4 to +5.

2. Oxygen (O): - In NO₂, the oxidation state of oxygen is -2. - In HNO₃, the oxidation state of oxygen is -2. - Therefore, the oxidation state of oxygen remains the same (-2) throughout the reaction.

3. Hydrogen (H): - In H₂O, the oxidation state of hydrogen is +1. - In HNO₃, the oxidation state of hydrogen is +1. - Therefore, the oxidation state of hydrogen remains the same (+1) throughout the reaction.

To summarize: - The oxidation state of nitrogen increases from +4 to +5. - The oxidation state of oxygen remains the same (-2). - The oxidation state of hydrogen remains the same (+1).
