**Understanding Chemical Formulas and Compound Names**

Chemical formulas and compound names are two essential tools used in chemistry to represent and identify chemical substances. A chemical formula is a way of expressing the composition of a compound, while a compound name is a way of describing the compound using a specific set of rules. In this article, we will explore the correct matching of chemical formulas with their corresponding names.

Chemical Formulas and Compound Names

Chemical formulas are written using a combination of letters and numbers, with each letter representing a specific element and each number representing the number of atoms of that element present in the compound. For example, the chemical formula $H_2O$ represents a compound composed of two hydrogen atoms and one oxygen atom.

On the other hand, compound names are written using a specific set of rules, which include the use of prefixes, suffixes, and root words. The prefixes and suffixes used in compound names are derived from Greek and Latin roots, and are used to indicate the number of atoms of each element present in the compound.

Analyzing the Options

Let's analyze the options provided in the question:

A. $N_2O$ , trinitrogen dioxide B. $N_2O$ , dinitrogen trioxide C. $N_2O_3$ , dinitrogen trioxide D. $N_2O_3$ , trinitrogen dioxide

To determine the correct answer, we need to understand the meaning of the prefixes and suffixes used in the compound names.

Dinitrogen: This prefix indicates the presence of two nitrogen atoms in the compound.
Trioxide: This suffix indicates the presence of three oxygen atoms in the compound.
Trinitrogen: This prefix indicates the presence of three nitrogen atoms in the compound.
Dioxide: This suffix indicates the presence of two oxygen atoms in the compound.

Evaluating the Options

Now, let's evaluate each option based on the meaning of the prefixes and suffixes used in the compound names:

Option A: $N_2O$ , trinitrogen dioxide. This option is incorrect because the prefix "trinitrogen" indicates the presence of three nitrogen atoms, while the suffix "dioxide" indicates the presence of two oxygen atoms.
Option B: $N_2O$ , dinitrogen trioxide. This option is incorrect because the prefix "dinitrogen" indicates the presence of two nitrogen atoms, while the suffix "trioxide" indicates the presence of three oxygen atoms.
Option C: $N_2O_3$ , dinitrogen trioxide. This option is incorrect because the prefix "dinitrogen" indicates the presence of two nitrogen atoms, while the suffix "trioxide" indicates the presence of three oxygen atoms.
Option D: $N_2O_3$ , trinitrogen dioxide. This option is incorrect because the prefix "trinitrogen" indicates the presence of three nitrogen atoms, while the suffix "dioxide" indicates the presence of two oxygen atoms.

Conclusion

Based on the analysis of the options, we can conclude that none of the options provided in the question correctly matches the chemical formula of a compound with its name.

However, if we consider the correct chemical formula for a compound with the name "dinitrogen trioxide", it would be $N_2O_3$ . This compound is composed of two nitrogen atoms and three oxygen atoms.

Therefore, the correct answer is:

C. $N_2O_3$ , dinitrogen trioxide

The prefixes and suffixes used in compound names are derived from Greek and Latin roots, and are used to indicate the number of atoms of each element present in the compound.

Q: What are the prefixes and suffixes used in compound names?

A: The prefixes and suffixes used in compound names are derived from Greek and Latin roots, and are used to indicate the number of atoms of each element present in the compound. Some common prefixes and suffixes used in compound names include:

Mono-: indicates the presence of one atom of an element
Di-: indicates the presence of two atoms of an element
Tri-: indicates the presence of three atoms of an element
Tetra-: indicates the presence of four atoms of an element
Penta-: indicates the presence of five atoms of an element
Hexa-: indicates the presence of six atoms of an element
Hepta-: indicates the presence of seven atoms of an element
Octa-: indicates the presence of eight atoms of an element
Non-: indicates the presence of nine atoms of an element
Deca-: indicates the presence of ten atoms of an element

Q: How do I write a chemical formula from a compound name?

A: To write a chemical formula from a compound name, you need to understand the meaning of the prefixes and suffixes used in the compound name. Here are the steps to follow:

Identify the elements present in the compound by looking at the root words used in the compound name.
Determine the number of atoms of each element present in the compound by looking at the prefixes used in the compound name.
Write the chemical formula by combining the elements and their respective numbers of atoms.

Q: How do I write a compound name from a chemical formula?

A: To write a compound name from a chemical formula, you need to understand the meaning of the prefixes and suffixes used in the compound name. Here are the steps to follow:
