Step 1
Which state symbols follow NaCl and H2O to complete the equation?
Answer
The sodium chloride (NaCl) produced in the reaction is typically dissolved in water, making its state symbol
aq (aqueous). The water (H2O) produced is in liquid form, indicated by the state symbol
l (liquid). Therefore, the correct answer is option D: NaCl(aq) and H2O(l).
