Question

2 NO + O2&#8594; 2 NO2is an example of :a)Combination reaction between 2 compoundsb)Combination reaction between an element and a compoundc)Decomposition reactiond)Combination reaction between 2 elementsCorrect answer is option 'B'. Can you explain this answer?

Answer

Combination reaction forms a single product after reaction. hence, it is clear that it is combination reaction . here, NO is a compound and o2 an element. hence, C

Answer

Here the single product i.e. NO2 gets formed from two different reactants i.e. NO and O2 are used. The NO is compund while O2 is element hence it is a combination reaction between compound and element.

Answer

Option B is correct...

Answer

Combination reaction
A chemical reaction in which two or more substances combine to form a single new substance is called a combination reaction.
Representation: A + B → AB

Answer

Combination reaction between an element and a compound

Combination reactions involve the combination of two or more substances to form a new compound. In this case, 2 NO (nitric oxide) and O2 (oxygen) combine to form 2 NO2 (nitrogen dioxide). Let's break down the reaction and explain why it is a combination reaction between an element and a compound.

1. Explanation of the reaction:
The given reaction is: 2 NO + O2 → 2 NO2

- NO is a compound, specifically a diatomic molecule consisting of nitrogen and oxygen.
- O2 is an element, in its molecular form, consisting of two oxygen atoms.
- NO2 is also a compound, consisting of nitrogen and oxygen.

2. Identification of reactants and products:
- Reactants: 2 NO and O2
- Products: 2 NO2

3. Analysis of the reaction type:
- The reactants in this reaction include a compound (NO) and an element (O2).
- The combination of these two substances results in the formation of a new compound (NO2).
- Therefore, this reaction represents a combination reaction between an element (O2) and a compound (NO).

4. Explanation of the reaction process:
- In the reaction, two molecules of NO combine with one molecule of O2.
- The oxygen atoms from O2 are added to the nitrogen atoms in NO to form NO2.
- The balanced equation shows that the number of atoms on both sides of the equation is equal, indicating a balanced reaction.

5. Conclusion:
- Based on the analysis, it can be concluded that the given reaction is an example of a combination reaction between an element (O2) and a compound (NO).
- This type of reaction is characterized by the formation of a new compound from the combination of two or more substances.
