Answer

Brief Explanations:

  1. Analyze the reaction ( \text{NaCl} + \text{AgNO}_3 \rightarrow \text{NaNO}_3 + \text{AgCl} ):
    • In this reaction, the cations (( \text{Na}^+ ) and ( \text{Ag}^+ )) and anions (( \text{Cl}^- ) and ( \text{NO}_3^- )) of the two reactants exchange places to form two new compounds.
    • A synthesis reaction involves combining substances to form a single product (e.g., ( A + B \rightarrow AB )), which is not the case here.
    • A decomposition reaction involves breaking down a compound into simpler substances (e.g., ( AB \rightarrow A + B )), which is not what's happening here.
    • Oxidation involves a change in oxidation states (loss of electrons), and there's no change in oxidation states for the elements here (Na is +1, Ag is +1, Cl is -1, N is +5, O is -2 throughout).
    • A replacement (specifically double - replacement) reaction occurs when the ions of two compounds exchange places in an aqueous solution to form two new compounds. This matches the given reaction as ( \text{Na}^+ ) from ( \text{NaCl} ) pairs with ( \text{NO}_3^- ) from ( \text{AgNO}_3 ), and ( \text{Ag}^+ ) from ( \text{AgNO}_3 ) pairs with ( \text{Cl}^- ) from ( \text{NaCl} ).
