Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. Hope this helps.
Explanation:
Alkanes are the simple hydrocarbons that have only carbon and hydrogen atoms attached to each other through single bonds.
General chemical formula of an alkane is
, where n is any integer.
For example, if n = 5 then formula of the alkane will be as follows.

= 
= 
A suffix "-ane" is added in the name of an alkane. So, an alkane with five carbon atoms will be known as pentane.
Explanation:
Hey It is due to physical properties
The hydrogen bonds that hold water molecules together in water's liquid and solid form give the substance high boiling and freezing points and strong surface tension. Because water molecules are held so tightly together, it takes a large amount of heat for water to boil.

Explanation:
Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. Each nuclesome is composed of DNA wound 1.65 times around eight histone proteins.
