What type of reaction is naclaq agno3aq --- agcls nano3aq?
It's a double replacement reaction. Correctly written, it's
NaCl(aq) + AgNO3(aq) --> AgCl(s) + NaNO3(aq). You can see in the
equation that the sodium replaces the silver, and the silver
replaces the sodium, hence the reaction type. The (aq) indicates a
substance in solution, and the (s) represents a precipitate.
