Question

the name for $\ce{nh_4no_3}$ is
ammonium nitrate.
ammonium nitrogen trioxide.
ammonia nitrogen oxide.
hydrogen nitrogen oxide.
hydrogen nitrate.

Explanation:

To name the compound \( \text{NH}_4\text{NO}_3 \), we identify the ions. \( \text{NH}_4^+ \) is the ammonium ion, and \( \text{NO}_3^- \) is the nitrate ion. When naming ionic compounds, we use the name of the cation (ammonium) followed by the name of the anion (nitrate). The other options are incorrect: "ammonium nitrogen trioxide" incorrectly names the anion, "ammonia nitrogen oxide" and "hydrogen nitrogen oxide" and "hydrogen nitrate" do not match the ions present.

Answer:

A. ammonium nitrate.
