Question

Identify the reaction equation, N2 + H2 NH3

A.decomposition reaction
B.double displacement reaction
C.neutralization reaction
D.single replacement reaction
E.synthesis reaction

Answer 1

It's a synthesis reaction since you're adding nitrogen with hydrogen to form ammonia

Answer 2

Answer: The correct answer is Option E.

Explanation:

For the given options:

• Option A: Decomposition reaction

This reaction is defined as the chemical reaction in which a single substance breaks down into two or more simpler substances.

$AB\rightarrow A+B$

• Option B: Double displacement reaction

This reaction is defined as the chemical reaction in which exchange of ions takes place.

$AB+CD\rightarrow AD+CB$

• Option C: Neutralization reaction

This reaction is defined as the chemical reaction in which an acid reacts with a base to produce a salt and water molecule.

$HX+BOH\rightarrow BX+H_2O$

• Option D: Single displacement reaction

This reaction is defined as the chemical reaction in which more reactive element displaces a less reactive element from its chemical reaction.

$AB+C\rightarrow CB+A$

• Option E: Synthesis reaction

This reaction is defined as the chemical reaction in which substances combine in their elemental state to form a single compound.

$A+B\rightarrow AB$

For the given chemical reaction:

$N_2+3H_2\rightarrow 2NH_3(g)$

This reaction is considered as a synthesis reaction because hydrogen and nitrogen are combining in their elemental state to produce ammonia molecule.

Hence, the correct answer is Option E.
