Answer:
Tea also contains two substances related to caffeine: theobromine and theophylline
pKa= -log(ka)
= -log(2.3*10^-9)
= 8.64
Now pH can be calculated using equation:
pH=pka+log(BrO-)/(HBrO)
8.08 =8.64+log(BrO-)/(HBrO)
log(BrO-)/(HBrO)=8.08-8.64
= -0.56
(BrO-)/(HBrO)= 10^-0.56
=0.275

Explanation:
The number of electrons in an atom of Q-95 will be 60 electrons.
The atomic number of an atom is the number of protons in the atom of the isotope
This number is unique to every atom and their isotope
An isotope of an atom is the existence of an atom having the same atomic number but different mass numbers.
Since atomic number the same as number of protons, they are the positively charged particles in an atom.
To have a negative charge, the number of electrons must be more than that of protons.
Charge = number of protons - number electrons
charge = -1
-1 = 59 - number of electrons
Number of electrons = 60 electrons
