<human>:  What is an example of an exchange reaction?
<bot>: An example of an exchange reaction is a double displacement reaction, in which two reactants exchange ions to form two new compounds. For example, the reaction between sodium chloride (NaCl) and silver nitrate (AgNO₃) produces silver chloride (AgCl) and sodium nitrate (NaNO₃):NaCl + AgNO₃ → AgCl + NaNO₃
