Question

Which type of reaction is Mg + S → MgS?

A. Polymerization
B. Synthesis
C. Replacement
D. Decomposition

I think it's synthesis, but idk

Answer 1

Answer: The correct answer is Option B.

Step-by-step explanation:

Polymerization reaction is defined as a reaction in which monomer molecules react together to form a polymer chains which are three-dimensional networks.

Synthesis reaction is defined as a chemical reaction in which two or more chemical species react in their naturally occurring state to form a single large compound.

`A+B\rightarrow AB`

Replacement reaction is defined as a chemical reaction in which exchange of ions takes place. They are of two types: Single replacement and double replacement.

`A+BC\rightarrow AC+B\\\\AB+CD\rightarrow AD+CB`

Decomposition reaction is a type of chemical reaction in which a larger molecule breaks down into two or more smaller molecules.

`AB\rightarrow A+B`

The given reaction follows:

`Mg(s)+S(s)\rightarrow MgS(s)`

This is a type of synthesis reaction.

Hence, the correct answer is Option B.

Answer 2

The type of reaction that is Mg +S→ MgS is a synthesis reaction

Explanation

Synthesis reaction as refers to as direct combination is a reaction in which two or more chemical species combine to form more complex product.

The reaction of Mg +S → MgS is a synthesis reaction because;

Mg combine with S to form a more complex product MgS
