a chemical reaction has the equation ( mathrm{agno}_{3}(s)+mathrm{nacl}(s)
ightarrow mathrm{agcl}(s)+mathrm{nano}_{3}(s) ). what type of reaction occurs between ( mathrm{agno}_{3} ) and ( mathrm{nacl} )?
a) synthesis
b) double displacement
c) single displacement
d) decomposition

Explanation:

To determine the reaction type, analyze the equation \( \text{AgNO}_3 (s) + \text{NaCl} (s)
ightarrow \text{AgCl} (s) + \text{NaNO}_3 (s) \). In a double displacement reaction, two compounds exchange ions. Here, \( \text{Ag}^+ \) from \( \text{AgNO}_3 \) swaps with \( \text{Na}^+ \) from \( \text{NaCl} \), forming \( \text{AgCl} \) and \( \text{NaNO}_3 \). Synthesis combines substances (not here), single displacement has one element replacing another (not here), and decomposition breaks a compound (not here). So it's double displacement.

Answer:

B) Double displacement
