Question

Какое из приведённых выражений не имеет смысла: 1) молекула азота 2) молекула аргона 3) молекула воздуха 4) молекула терпинеола 5) молекула аспирина

Answer 1

The expression that does not make sense is 3) molecule of air. Air is not a pure substance, but a mixture of different gases, mainly nitrogen and oxygen. Therefore, air does not have a definite molecular formula or structure. The other expressions refer to specific chemical compounds that have well-defined molecular formulas and structures. For example, the molecule of nitrogen is N2, the molecule of argon is Ar, the molecule of terpineol is C10H18O, and the molecule of aspirin is C9H8O4. You can find more information about these molecules in the web search results I provided.
