Question

For each of the following types of reactions, write a general reaction formula in the symbolic form—for example, A + B → AB.

Answer 1

Answer: The given reaction is the generic reaction for synthesis reaction.

Explanation:

For the given options:

• Option A: Single displacement reaction

Single displacement reaction is defined as the reaction in which more reactive element displaces the less reactive element fro its chemical reaction.

$A+BC\rightarrow AC+B$

• Option B: Double-displacement reaction

Double-displacement reaction is defined as the reaction in which exchange of ions takes place.

$AB+CD\rightarrow AD+CB$

• Option C: Synthesis

Synthesis reaction is defined as the reaction in which two substances combine in their elemental state to form one single product

$A+B\rightarrow AB$

• Option D: Decomposition

Decomposition reaction is defined as the chemical reaction in which a large substance breaks down into two or more small substances

$AB\rightarrow A+B$

Hence, the given reaction is the generic reaction for synthesis reaction.

Answer 2

I am taking the same test ;)

1.) Single-displacement  

AB + C --> AC + B  

2.) Double-displacement

AB + CD --> AD + CB

3.) Synthesis

A + B --> AB

4.) Decomposition

AB --> A + B

Hope this helps!
