Question

identify the type of reaction for the chemical equation: mg + 2agno₃ → mg(no₃)₂ + 2ag
synthesis reaction
double replacement reaction
decomposition reaction
single replacement reaction

Explanation:

In the reaction \( \text{Mg} + 2\text{AgNO}_3
ightarrow \text{Mg(NO}_3\text{)}_2 + 2\text{Ag} \), a single element (Mg) replaces another element (Ag) in a compound (\( \text{AgNO}_3 \)). This fits the definition of a single replacement reaction, where one element takes the place of another in a compound. Synthesis reactions combine substances, decomposition breaks down, and double replacement involves two compounds exchanging ions, which is not the case here.

Answer:

Single replacement reaction (the option labeled "Single replacement reaction")
