Question

Which type of reaction is Mg + S → MgS?

polymerization
synthesis
replacement
decomposition

Answer 1

The reaction \( \text{Mg} + \text{S} \rightarrow \text{MgS} \) is a **synthesis** reaction. In a synthesis reaction, two or more reactants combine to form a single product. In this case, magnesium (Mg) and sulfur (S) combine to form magnesium sulfide (MgS).
