Answer:
the radioactive half-life of an atom can depend on how it is bonded to other atoms. by changing the neighboring atoms that are bonded to a radioactive isotope, we can change its half-life.
Explanation:
The question is incomplete, complete question is :
You need to produce a buffer solution that has a pH of 5.50. You already have a solution that contains 10 mmol (millimoles) of acetic acid. How many millimoles of acetate (the conjugate base of acetic acid) will you need to add to this solution? The pka of acetic acid is 4.74.
Answer:
33.11 millimoles of acetate we will need to add to this solution.
Explanation:
To calculate the pH of acidic buffer, we use the equation given by Henderson Hasselbalch:
![pH=pK_a+\log(\frac{[salt]}{[acid]})](https://tex.z-dn.net/?f=pH%3DpK_a%2B%5Clog%28%5Cfrac%7B%5Bsalt%5D%7D%7B%5Bacid%5D%7D%29)
Where :
tex]pK_a[/tex] = negative logarithm of acid dissociation constant of acid
[salt] = Concentration of salt
[Acid] = Concentration of salt
We have:
pH = 5.26
[salt] =![[CH_3COO^-]](https://tex.z-dn.net/?f=%5BCH_3COO%5E-%5D)
= ?
[acid] = ![[CH_3COOH]=10.0 mmol](https://tex.z-dn.net/?f=%5BCH_3COOH%5D%3D10.0%20mmol)
![5.26=4.74+\log(\frac{[CH_3COO^-]}{[10.0 mmol]})](https://tex.z-dn.net/?f=5.26%3D4.74%2B%5Clog%28%5Cfrac%7B%5BCH_3COO%5E-%5D%7D%7B%5B10.0%20mmol%5D%7D%29)
![[CH_3COO^-]=33.11 mmol](https://tex.z-dn.net/?f=%5BCH_3COO%5E-%5D%3D33.11%20mmol)
33.11 millimoles of acetate we will need to add to this solution.
The question is incomplete, the complete question is;
Arrange the isotopes of chlorine and sulfur in order of decreasing number of neutrons. Rank the isotopes from most to fewest neutrons. To rank items as equivalent S-33,S-36,S-34,Cl-35,S-32,Cl-37
The isotopes of sulphur arranged in order of decreasing number of neutrons is; S-36, S-34, S-33, S-32. The isotopes of chlorine arranged in order of decreasing number of neutrons is; Cl-37, Cl-35.
Isotopes are atoms of the same element having different mass numbers but the same atomic number.
Isotopes differ in their number of neutrons. The number of neutrons is obtained by subtracting the atomic number of an isotope from its mass number.
The number of neutrons in the isotopes of sulphur are;
S-36 (20 neutrons)
S-34 (18 neutrons)
S-33 (17 neutrons)
S-32 (16 neutrons)
The number of neutrons in the isotopes of chlorine are;
Cl-37 (20 neutrons)
Cl-35 (18 neutrons)
