Question

The reaction 2NO(g) + O2(g) → 2NO2(g) is a synthesis reaction. True False

Answer 1

Answer: true

Explanation: I took the quiz

Answer 2

True

Step-by-step explanation:

Chemical reactions are broadly classified as:

1) Synthesis or combination reaction in which two or more substances react to form a single product

2) Decomposition reaction in which a complex substance breaks down into simpler molecules

3) Combustion reaction in which a substance like a hydrocarbon reacts with oxygen to form an carbon dioxide and water

4) Single displacement reaction in which a more reactive element replaces a less reactive element

5) Double displacement reaction which involves exchange of ions in solution

The given reaction is:

2NO + O2 → 2NO2

Here two substances combine to form a single molecule. This is an example of a synthesis reaction.
