Answer:
Explanation:
Hello,
By considering the rate law:
![ln(\frac{[CO_2]}{[CO_2]_0} )=-kt\\](https://tex.z-dn.net/?f=ln%28%5Cfrac%7B%5BCO_2%5D%7D%7B%5BCO_2%5D_0%7D%20%29%3D-kt%5C%5C)
Solving for the time, we've got:
![k=-\frac{ln (\frac{[CO_2]}{[CO_2]_0 })}{t}\\\\k=-\frac{ln(\frac{56.0mmol*dm^{-3} }{220mmol*dm^{-3} })}{1.22x10^{4}s }\\ \\k=1.12x10^{-4}s](https://tex.z-dn.net/?f=k%3D-%5Cfrac%7Bln%20%28%5Cfrac%7B%5BCO_2%5D%7D%7B%5BCO_2%5D_0%20%7D%29%7D%7Bt%7D%5C%5C%5C%5Ck%3D-%5Cfrac%7Bln%28%5Cfrac%7B56.0mmol%2Adm%5E%7B-3%7D%20%7D%7B220mmol%2Adm%5E%7B-3%7D%20%7D%29%7D%7B1.22x10%5E%7B4%7Ds%20%7D%5C%5C%20%20%5C%5Ck%3D1.12x10%5E%7B-4%7Ds)
Best regards.
Cancer cells are damaged cells that uncontrollably divide creating even more damaged cells that as continue to divide as well
Element name: Neon
element symbol: Ne
atomic number: 10
atomic mass: 20.1797
number of protons: 10
number of neutrons: 10
number of electrons: 2,8
interesting fact: the name means new, and it is pulled out of the air.
for the rest just add a neon bohr model ig
Answer:
C). Electronegativity.
Explanation:
'Electronegativity' is described as the tendency or a measure of the ability of an atom or molecule to attract electrons that leads to the formation of chemical bonds. It is denoted by 'χ', a Greek letter. The elements like Fluorine having a very high rate of electronegativity, its atom would attract the electrons more strongly while the elements with lesser electronegativity like Cesium would possess a lesser tendency to attract electrons towards it in order to form a bond. Thus, <u>option C</u> is the correct answer.
