Answer 1

Answer:

1.Air is a homogeneous mixture of gases as it is primarily made up of nitrogen and oxygen. Its elements are not readily separated or distinguished from one another.

2.Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. ... This allows the water molecule to become attracted to many other different types of molecules.

3.It is said that there is no alternative to water for cleaning purposes. Water is provided by nature. Water is available in abundance.So as there is more water on Earth we use water for cleaning purposes. We do not use other substances because some substances are very expensive and some substances are very scare .
