Final answer:
In the reaction, both N3- and H2O can act as Brønsted-Lowry bases by being capable of accepting a proton. Hence, more than one response is correct.
Step-by-step explanation:
In the provided chemical reaction, N3- and H2O can both act as Brønsted-Lowry bases. A Brønsted-Lowry base is defined as a substance that can accept a proton (H+). In the reaction, the N3- ion accepts a proton from H2O, forming HN3 and leaving behind OH-, showing that N3- acts as a base. Similarly, H2O can also act as a base, for instance, when it reacts with a strong acid like HCl, accepting a proton to form H3O+.
Therefore, the correct answer to the student's question would be d) More than one response is correct because both N3- and H2O can function as bases in this scenario.
