NEED HELP ASAP Identify the type of reation. 2 NO2 > 202 + N2
A)
Synthesis
B)
Decomposition
C)
Single Replacement
D)
Double Replacement

B)  Decomposition

Explanation:

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

AB → A + B

Chemical equation:

2NO₂    → 2O₂ + N₂

The given reaction is decomposition reaction. NO₂ decomposed to give nitrogen and oxygen. All other options are incorrect because,

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AC +BD

the volume increases
