Expressions without Meaning

There are certain expressions that do not make sense or lack meaning. Let's analyze the expressions you provided:

A) Molecules of air: This expression does have meaning. Air is composed of various gases, such as nitrogen, oxygen, carbon dioxide, and others. These gases consist of molecules, so the concept of "molecules of air" is valid.

B) Molecules of river water: This expression also has meaning. River water contains various substances, including dissolved minerals, organic matter, and gases. These substances are made up of molecules, so the concept of "molecules of river water" is valid.

C) Molecules of table salt: This expression has meaning as well. Table salt, or sodium chloride (NaCl), is a compound made up of sodium and chlorine ions. These ions are held together by ionic bonds, and each ion consists of multiple atoms. Therefore, the concept of "molecules of table salt" is valid.

D) Molecules of quartz: This expression is not accurate. Quartz is a mineral composed of silicon and oxygen atoms arranged in a specific crystal structure. However, quartz does not exist as individual molecules. Instead, it is made up of a repeating pattern of atoms. Therefore, the concept of "molecules of quartz" is not meaningful.

In summary, expressions A, B, and C have meaning, while expression D does not.
