which type of reaction is nacl + agno₃ → nano₃ + agcl?\no synthesis\no decomposition\no oxidation\no…

Answer:

D. replacement

Explanation:

Step1: Recall reaction - type definitions

Synthesis is $A + B\rightarrow AB$. Decomposition is $AB\rightarrow A + B$. Oxidation involves change in oxidation states. Replacement has $AB+CD\rightarrow AD + CB$.

Step2: Analyze given reaction

In $NaCl + AgNO_3\rightarrow NaNO_3+AgCl$, the cations ($Na^+$ and $Ag^+$) exchange anions ($Cl^-$ and $NO_3^-$). This is a double - replacement reaction. So it is a replacement reaction.
