Answer:
See the answer below
Explanation:
There are several scientists that contributed to the understanding of the cell. Some of them and their contributions are as follows:
Anton van Leeuwenhoek: He invented the first primitive microscope and was able to view some unicellular microscopic cells such as protozoans and bacteria. He disproved the theory of spontaneous generation by his discoveries.
Robert Hooke (1665): He improved further on the microscope invented by Leeuwenhoek and was able to view compartment-like rooms when tissues of cork were sectioned. He tagged the compartment as 'cell'.
Schleiden (1804–1881): Using an improved microscope, he was able to extensively study plant tissues and borrowed the word coined by Hooke (cell) to describe the component of the plant tissues.
Theodor Schwann (1810–1882): He studied animal tissues and made a similar observation as Schleiden.
Through their various studies, Schleiden, Schwann, and another scientist, Rudolf Virchow later developed what is nowadays known as the cell theory
Answer: Thus the value of 
is 110.25
Explanation:
Initial moles of 
= 0.500 mole
Initial moles of 
= 0.500 mole
Volume of container = 1 L
Initial concentration of 
Initial concentration of 
equilibrium concentration of 
[/tex]
The given balanced equilibrium reaction is,
Initial conc. 0.500 M 0.500 M 0 M
At eqm. conc. (0.500-x) M (0.500-x) M (2x) M
The expression for equilibrium constant for this reaction will be,
![K_c=\frac{[IBr]^2}{[Br_2]\times [I_2]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BIBr%5D%5E2%7D%7B%5BBr_2%5D%5Ctimes%20%5BI_2%5D%7D)
we are given : 2x = 0.84 M
x= 0.42
Now put all the given values in this expression, we get :
Thus the value of the equilibrium constant is 110.25
By increasing the action energy
