Explanation:
It is known that relation between ,
, and pH is as follows.
Also, it is known that for hydrogen is equal to zero.
Hence, substituting the given values into the above equation as follows.
0.238 V = 0 - (\frac{0.0591}{1}) \times log[H^{+}] [/tex]
= 4.03
= antilog 4.03
= 3.5
As, pH = .
Thus, we can conclude that pH of the given unknown solution at 298 K is 3.5.
Answer:
The correct option is: A. carbon-12
Explanation:
The CNO cycle, the abbreviation for the carbon-nitrogen-oxygen cycle, is a catalytic cycle by which the stars produce helium from elemental hydrogen, via a series of nuclear fusion reactions.
This cycle involves the fusion of four protons with carbon (), nitrogen isotope (
), and oxygen isotope (
), to give an alpha particle and two electron neutrinos and positrons.
The reaction involves the regeneration of carbon () nucleus in the last step.
