Question

Identify the reaction type shown and describe the clues that were used to identify it.
NH4NO3 → N2O + 2H2O

Answer 1

Answer : Decomposition Reaction.

Explanation : When a single molecular compound breaks down it gets divided into smaller molecules it is called as decomposition reactions. In this reaction of ammonium nitrate, it gets broken down into a dinitrogen monoxide and two water molecule.

NH_{4}NO_{3} ----> N_{2}O + 2H_{2}ONH

4

NO

3

−−−−>N

2

O+2H

2

O

This reaction completely agrees with the statement of decomposition reaction; therefore, it is a decomposition reaction.

Answer 2

The reaction type shown here is a decomposition reaction.

• A decomposition reaction is a type of chemical reaction. which involves the breakage of a complex compound into two or more simpler compounds.
• This reaction is just the reverse or opposite reaction of the combination reaction.
• AB -> A + B
• The clues that depicts that it is a decomposition reaction are that $NH_{4} NO_{3}$ is a complex compound that can be split into two or more compounds.
• Another clue is that water and $NO_{2}$ are formed on the product side and both of them are simple compounds.

Hence, the reaction type shown here is a decomposition reaction.
