Question

write three reasons in the supporr of the statement; Air is a mixture but NaCl is a compound​

Answer 1

Something like table salt (NaCl) is a compound because it is made from more than one kind of element (sodium and chlorine), but it is not a molecule because the bond that holds NaCl together is an ionic bond. If you like, you can say that sodium chloride is an ionic compound.

Oxygen in the atmosphere is a molecule because it contains molecular bonds. It is not a compound because it is made from atoms of only one element - oxygen. This type of molecule is called a diatomic molecule, a molecule made from two atoms of the same type.

Answer 2

Answer:

Air is a mixture but NaCl is a compound,  because of the following reasons-

Explanation:

1. Air has several components or compounds which includes oxygen, carbon dioxide, methane, nitrogen, etc. whereas NaCl (common salt) has only two components- Na (sodium) and Cl (chlorine).
2. Air can be separated into its constituents such as oxygen, nitrogen, etc. by fractional distillation of liquid air. But separation of NaCl is quite a difficult task
3. Air shows the properties of all gases present in it. Whereas NaCl has different properties with different reactions.
