Transcript text: 7) The name of the binary compound $\mathrm{N}_{2} \mathrm{O}_{3}$ is $\qquad$
A. nitrogen oxide
B. dinitrogen trioxide
C. nitrous oxide
D. nitrogen (IV) oxide
Solution
Solution Steps
Step 1: Identify the Type of Compound
The compound \(\mathrm{N}_2\mathrm{O}_3\) is a binary compound composed of two nonmetals: nitrogen (N) and oxygen (O). Such compounds are typically named using prefixes to indicate the number of each type of atom present.
Step 2: Determine the Prefixes for Each Element
In binary compounds of nonmetals, the prefixes are used to denote the number of atoms:
"Di-" indicates two atoms.
"Tri-" indicates three atoms.
For \(\mathrm{N}_2\mathrm{O}_3\):
There are two nitrogen atoms, so the prefix "di-" is used for nitrogen.
There are three oxygen atoms, so the prefix "tri-" is used for oxygen.
Step 3: Construct the Name of the Compound
Using the prefixes determined in the previous step, the name of the compound is constructed as follows:
"Dinitrogen" for \(\mathrm{N}_2\)
"Trioxide" for \(\mathrm{O}_3\)
Thus, the name of the compound \(\mathrm{N}_2\mathrm{O}_3\) is "dinitrogen trioxide."
Final Answer
The answer is \(\boxed{\text{B. dinitrogen trioxide}}\).
