Identify the reaction type shown and describe the clues that were used to identify it.

Question

NH4NO3 → N2O + 2H2O

Answer 1

The reaction shown is a decomposition reaction.

Clues for identification:

1. Single Reactant: The presence of a single reactant, ammonium nitrate (NH4NO3), which breaks down into two products (N2O and H2O), is a strong indicator of a decomposition reaction. Decomposition reactions typically involve one reactant that splits into two or more products.

2. Product Formation: The formation of nitrogen oxide (N2O) and water (H2O) suggests that the original compound breaks down into simpler substances, characteristic of decomposition.

3. Type of Reaction: The breakdown of ammonium nitrate can also suggest thermal decomposition, particularly when ammonium nitrate is heated, as it often decomposes to produce nitrous oxide and water.

These clues confirm that the given reaction is a decomposition reaction.
