Answer:
<u>Polymerization process(Addition)</u>
Explanation:
<u>Polymerization </u>: The process in which small units called monomers combine to produce large mass compound is called polymerization reaction.These large masses are also called macromolecules.
The formation of polymers can occur by addition or condensation process .
<u><em>Addition</em></u> : In addition reaction small units add to previous units
<em><u>Condensation</u></em> : In condensation , a small molecule like water , carbon dioxide get eliminated when the unit attach to previous unit.
Some natural polymers are Proteins , carbohydrates , lipids , cellulose.
Polythene = addition polymerisation also known as Chain growth polymerisation.

This occur in three steps:
1. Chain Initiation : The start of the reaction occurs with the radical. These are generated from some organic peroxide and have general representation:

2 . Chain Growth = When the small units goes on adding to the previous units , Chain length increases and this is called chain growth.
3. Chain Termination = The chain continues to grow more and more until not forced to stop. This termination of chain growth is called chain termination
Answer:
D. The nucleus of an atom of lithium splits, resulting in smaller fragments and the release of a large amount of energy.
Explanation:
Fission is the splitting of a nucleus, so this is the only option that involves fission.
A is wrong. Li atoms do not bond to form molecules. Instead, the nuclei are immersed in a sea of electrons.
B is wrong. The joining of two nuclei is fusion.
C is wrong. Adding an electron to an atom of lithium is not a nuclear reaction.
Answer:
Height = 1.9493 cm
Width = 1.9493 cm
Depth = 1.9493 cm
Solution:
Data Given:
Mass = 20 g
Density = 2.7 g/mL
Step 1: Calculate the Volume,
As,
Density = Mass ÷ Volume
Or,
Volume = Mass ÷ Density
Putting values,
Volume = 20 g ÷ 2.7 g/mL
Volume = 7.407 mL or 7.407 cm³
Step 2: Calculate Dimensions of the Cube:
As we know,
Volume = length × width × depth
So, we will take the cube root of 7.407 cm³ which is 1.9493 cm.
Hence,
Volume = 1.9493 cm × 1.9493 cm × 1.9493 cm
Volume = 7.407 cm³
Answer:
<em><u>Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).</u></em>
