Air is a mixture, not a compound. A mixture is a combination of two or more substances that are physically combined and can be separated by physical means, such as filtration or distillation. Air is composed of a mixture of gases, primarily nitrogen (78%), oxygen (21%), and small amounts of other gases such as carbon dioxide, argon, and water vapor.
Water, on the other hand, is a compound. A compound is a substance made up of two or more different elements that are chemically bonded together in a fixed ratio. Water is composed of two hydrogen atoms bonded to one oxygen atom, forming the chemical compound H2O. This means that water cannot be separated into its constituent elements by physical means, but only through chemical reactions.

Air is a mixture, while water is a compound.
A compound is a substance made of two or more different elements chemically combined in fixed proportions. Water is a compound composed of hydrogen and oxygen in a 2:1 ratio by mass. This means that for every two atoms of hydrogen in a water molecule, there will always be one atom of oxygen.
A mixture is a combination of two or more substances that are not chemically bonded. The substances retain their identity and are mixed in varying proportions. Air is a mixture of several gases, including nitrogen, oxygen, argon, and carbon dioxide. The proportions of these gases in the air can vary depending on factors such as location and altitude.
Here is a table summarizing the key differences between compounds and mixtures:
| Feature | Compound | Mixture | |---|---|---| | Composition | Chemically combined elements in fixed proportions | Physically combined substances | | Properties | Properties depend on the elements and proportions | Properties depend on the proportions of the substances | | Identity of substances | Cannot be separated without breaking chemical bonds | Can be separated without breaking chemical bonds | | Examples | Water, salt, sugar | Air, sand, salad dressing |
In summary, air is a mixture because it is a combination of gases that are not chemically bonded and can be separated without breaking chemical bonds. On the other hand, water is a compound because it is composed of hydrogen and oxygen that are chemically combined in a fixed proportion and cannot be separated without breaking chemical bonds.
