Answer:
It's one of the key standards of science, and it's critical to the point that it has become data a significant number of us underestimate. Realizing that every single living thing are comprised of cells permits us to see how creatures are made, develop, and kick the bucket. That data encourages us see how new life is made, why living beings take the structure they do, how malignant growth spreads, how maladies can be overseen, and that's only the tip of the iceberg. Cells even assist us with understanding principal issues, for example, life and passing: a creature whose cells are living is viewed as alive, while one whose cells are dead is viewed as dead. Illness, how creatures develop, and passing were substantially more of a puzzle contrasted with what we know today.
Explanation:
The cell theory is one of the primary hypotheses of science. It has three primary parts:
- Every single living thing are comprised of cells.
- Cells are the fundamental structure squares of life.
- All cells originate from previous cells made through the procedure of cell division.
As our logical information has expanded after some time, extra parts have been added to the theory. Schleiden and Schwann, just as Virchow, are for the most part observed as the organizers of the cell theory, because of their spearheading logical work during the 1800s. The cell theory is significant in light of the fact that it influences about each part of science, from our comprehension of life and passing, to how we oversee ailments, and the sky is the limit from there.
Different pieces of the cell theory since they weren't a piece of the first definition, yet it's as yet valuable to know about them:
- Vitality stream happens inside cells.
- Innate data is passed from cell to cell.
- All cells have a similar fundamental substance piece.

Answer:
a) the repeat unit molecular weight of PTFE MW = 100.015 g/mole
b) the number-average molecular weight for a PTFE for which the degree of polymerization is 10,000 щₙ = 1000150 g/mole
Explanation:
Given that;
PTFE which is also called Polytetrafluoroethylene
structure of repeat unit of Polytetrafluoroethylene
(C2F4)n
a)
To compute the repeat unit molecular weight
we say
MW = 2( atomic weight of C ) + 4( atomic weight of F)
MW = 2 (12.0107) + 4 ( 18.9984)
MW = 100.015 g/mole
therefore the repeat unit molecular weight of PTFE MW = 100.015 g/mole
b)
To compute the number-average molecular weight for PTFE of which the degree of polymerization is 10,000
we say
DP = щₙ / MW
where щₙ is the number of average molecular weight,
MW is the repeat unit molecular weight give as 100.015 g/mole
DP is degree of polymerization which is 10,000
Now we substitute
10,000 = щₙ / 100.015
щₙ = 10,000 × 100.015
щₙ = 1000150 g/mole
Therefore the number-average molecular weight for a PTFE for which the degree of polymerization is 10,000 щₙ = 1000150 g/mole
