Answer:

Cotton

Explanation:

Cellulose, another natural polymer, is the main structural component of plants. Most natural polymers are condensation polymers, and in their formation from monomers water is a by-product.

<u>Answer:</u>

<em>B. Cotton</em>

<em></em>

<u>Explanation:</u>

A polymer is a macro molecule or gaint molecule which is formed as a chain from  many small molecules(which is called as a monomer).

Polymer is a repeating unit of many monomers.

For example  

Ethylene or ethane formula is C2H4.

Many ethane molecules under particular temperature and pressure conditions undergo the polymerization process to form polyethene. During this process the double bond breaks and becomes single bond and produces a long chain which we call it as a polymer.

The repeating unit of Cotton polymer is called as Cellubiose which is made up of 2 glucose units.

The number of units which forms the polymer (degree of polymerization) is about 5000 cellubiose units.

How can electronegativity be used to explain the reaction we see in terms of the numbers and types of bonded being formed in lit
kolezko [41]

Explanation:

Lithium is an electropositive element that readily loses electrons.

Oxygen is electronegative and it will readily accept electrons.

 Due to this significant electronegativity differences between the two species they form electrovalent or ionic bonds between them.

  2atoms of Li lose two electrons:

      Li  →  Li²⁺ + e⁻

             Lithium isoelectronic with helium

 For oxygen;

      O + 2e⁻   →  O²⁻

                          Oxygen is isoelectronic with Neon

Two ions of the lithium combines with the oxygen to form the bond;

                   4Li + O₂  →  2Li₂O

The electrostatic attraction between the two ions forms the ionic bond

What is crystal field splitting?
kvv77 [185]

Answer:

Crystal field splitting is the difference in energy between d orbitals of ligands. Crystal field splitting number is denoted by the capital Greek letter Δ. Crystal field splitting explains the difference in color between two similar metal-ligand complexes.

Please give me the reasons of the solution!
irinina [24]

1. The answer is option E, that is None of the above is correct.

As a polymer becomes more crystalline,

its melting point doesn't decreases, its density doesn't decreases, its stiffness doesn't decreases and its yield stress doesn't decreases.

2. The answer is option B, that is the molecules are arranged in sheets, with their long axes parallel and their ends aligned as well.

In the smectic A liquid-crystalline phase, molecules are arranged in sheets, with their long axes parallel and their ends aligned as well.

3.  For a substitutional alloy to form, the two metals combined must have similar atomic radii and chemical bonding properties.
