That factor appears when you actually do the quite complex maths that lead to the principle; it's quantum mechanics, and it's not something that can be shown easily.
What is important to note is that this factor
is not important. What is important is that the uncertainty
is approximately of the order of
, which is a characteristic value that appears in many (most) formulas dealing with quantum mechanics.
Explanation:
Air is a combination of other gases, dust particles, pollens, spores etc. This means that air is a heterogeneous mixture where particles are unevenly distributed.
Air is not considered as a pure substance because there is not one element present in air. A substance which contains only one type of element is called a pure substance.
Therefore, it is wrong to use the term 'Pure Air' in Science.

Explanation:
This reaction between an acid and a base is called a neutralization reaction and the products of this reaction are salt and water..The base in this case is sodium hydroxide, acid is hydrochloric acid and the salt formed id sodium chloride.
