Question:

Select the correct answer. What is the chemical name of the compound represented by the formula [tex]\( \text{N}_2\text{O}_3 \)[/tex]? Use the list of polyatomic ions and the periodic table to help you answer.

Options:
A. nickel oxode
B. nickel(II) oxide
C. nickel(III) oxode
D. nickel(VI) oxide



Answer :

To determine the correct chemical name for the compound represented by the formula [tex]\( N_2O_3 \)[/tex], we can follow these steps:

1. Identify the elements in the compound:
- [tex]\(N\)[/tex] stands for nitrogen.
- [tex]\(O\)[/tex] stands for oxygen.

2. Determine the number of atoms for each element in the formula:
- [tex]\( N_2 \)[/tex] means there are 2 nitrogen atoms.
- [tex]\( O_3 \)[/tex] means there are 3 oxygen atoms.

3. Apply the appropriate prefixes for the number of atoms according to the rules of chemical nomenclature:
- The prefix for 2 is "di", so [tex]\( N_2 \)[/tex] is "dinitrogen".
- The prefix for 3 is "tri", so [tex]\( O_3 \)[/tex] is "trioxide".

4. Combine the names of the elements with their prefixes:
- Combining "dinitrogen" and "trioxide" gives us the name of the compound.

Thus, the chemical name for the compound with the formula [tex]\( N_2O_3 \)[/tex] is dinitrogen trioxide.

As none of the answer choices listed (nickel oxode, nickel(II) oxide, nickel(III) oxode, and nickel(VI) oxide) match the name dinitrogen trioxide, we must conclude that the given options are incorrect and do not correspond to the formula [tex]\( N_2O_3 \)[/tex]. The correct name based on the formula [tex]\( N_2O_3 \)[/tex] should be "dinitrogen trioxide."
