Question

A student needs to use sodium nitride in an experiment and finds a chemical with the formula NaNO3 . Is this the correct compound? Why or why not?

A. Yes, NaNO3 is the formula for sodium nitride.
B. No, NaN is the formula for sodium nitride; NaNO3 is the formula for sodium nitrate.
C. No, NaN is the formula for sodium nitride; NaNO3 is the formula sodium nitrite.
D. No, Na3N is the formula for sodium nitride; NaNO3 is the formula for sodium nitrat

Answer 1

No, NaNO3 is not the correct compound for sodium nitride; the correct formula for sodium nitride is Na3N, while NaNO3 represents sodium nitrate.

Step-by-step explanation:

The correct answer is D. No, Na3N is the formula for sodium nitride; NaNO3 is the formula for sodium nitrate. Sodium nitride consists of three sodium ions (Na+) for every nitride ion (N3-), which gives the compound a chemical formula of Na3N. In contrast, sodium nitrate is composed of one sodium ion (Na+) and one nitrate ion (NO3-), resulting in the chemical formula NaNO3. The names of ionic compounds are based on the ions they contain and the ratio of these ions.

Answer 2

Yes, NaNO3 is the formula for sodium nitride.
