Good conductors of electricity and heat, form cations by loss of electrons,
Answer:
The pH of the sweater containing Hydrogen ion concentration
is
<u>8</u>
<u></u>
Explanation:
pH = It is the negative logarithm of activity (concentration) of hydrogen ions.
pH = -log([H+])
Now, In the question the concentration of [H+] ions is :
![[H^{+}]=1\times 10^{-8}](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%3D1%5Ctimes%2010%5E%7B-8%7D)
![pH = -log(1\times 10^{-8})](https://tex.z-dn.net/?f=pH%20%3D%20-log%281%5Ctimes%2010%5E%7B-8%7D%29)
use the relation:
![log(10^{-a})=a](https://tex.z-dn.net/?f=log%2810%5E%7B-a%7D%29%3Da)
![pH= -(-8)](https://tex.z-dn.net/?f=pH%3D%20-%28-8%29)
pH = 8
Note : <em><u> 1 times 10 to the power of 8 must be" 1 times 10 to the power of -8"</u></em>
If the concentration is
![[H^{+}]=1\times 10^{8}](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%3D1%5Ctimes%2010%5E%7B8%7D)
Then pH = -8 , which is not possible . So in that case the pH calculation is by other method
Explanation:
plzz tell me the ans even i also want to know plzzzz someone say ans
I would say because the respiratory system brings in the oxygen for the body and the circulatory system moves it throughout the body with the blood
Explanation:
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.
