A polymer instance has chain of different type of lengths and hence its molecular mass is all the time expressed as an average on the other hand natural polymer like proteins consist of chain of similar length and therefore they have specific molecular mass.
The atomic volume of a polymer can be illustrated in two ways.
(a) Number average molecular mass (M¯N)
(b) Weight average molecular mass (M¯W)
Bond strength in hydrocarbons As much shorter is the bond size, the greater is the compression among molecules atomic nuclei and therefore greater is the strength of that bond.
The Ca 2+ and Mg 2+ ions in hard water form scum with soap. Therefore they don''t form lather and therefore don''t clean the dirt.
Since fluorine is very electronegative as a result hydrogen develop a very positive character. As a result the H-bonding is very tough because of large difference in electronega
The present atomic weight scale is based on: (1) C 12 (2) O 16 (3) H 1 (4)C 13 Ans: C 12
The electronic configuration 1s 2 , 2s 2 , 2p 1 x , 2p 1 z : (1) Oxygen (2) Nitrogen (3) Hydrogen (4) Fluorine Ans: Nitrogen
