The given equation:
NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
is an acid-base reaction where sodium hydroxide (NaOH) reacts with hydrochloric acid (HCl) to produce sodium chloride (NaCl) and water (H2O). This type of reaction can also be classified as a double replacement reaction.
So, the correct response is:
double replacement
