Question

Water is a mixture.
A. True
B. False

Answer 1

Hint: Water is a molecule that is made up of two molecules of hydrogen and one molecule of oxygen. And a mixture is referred to as a substance that is made up by mixing more than one component physically, and for a molecule to be called as a mixture the identities should retain back.

Complete answer:
Let us know about the properties of water and then we will generalize it is a mixture or not;

Water is formed by the formation of a chemical bond between $2$ hydrogen atoms and one oxygen atom.
And the bond between water can be broken by chemical reaction one of such methods is electrolysis in which it breaks down into constituent ions and it gives ${H^ + }$ and $O{H^ - }$ ions in a solution. Whereas, for a mixture, the components are easily separated by physical means. Example:- Sand and water can be easily separated by physical means and Water is a compound because it can only be separated into hydrogen and oxygen atoms by chemical reaction. And the properties of water are very different from that of the oxygen and hydrogen, for a molecule to be a mixture the properties should match from the constituents it is made up of.
Hence, the above statements suggest that water is not a mixture.

So, the correct answer is B which is False.

Note:
Azeotropes is one of the exceptions when it comes to separation by the physical process as azeotropes are the kind of mixtures that require both physical as well as chemical processes for its separation.
