Answer:
7.07
Explanation:
HA = weak acid = 0.053
A+ = conjugate base = 0.045
Ka = 7.2x10^-8
Ka = [H+][A-]/HA
7 2x10^-8 = [H+][0.045]/0.053
[H+] = 7.2x10^-8 x 0.053/0.045
= 8.48x10^-8
PH = -log[H+]
= -log[8.48x10^-8]
PH = -[login.48 + log10^-8]
PH = -0.928 - (-8)log10
= 7.07
There are TWO atoms in one molecule of hydrogen.
The correct answer is letter a, whereas, carrying capacity
in captivity increases population size. It is because the carrying captivity is
the one responsible for having a maximum population size in which will help in
sustaining the necessities that the species need in the environment in which
makes it responsible for the population size to increase depending on its
capacity. The correct answer is letter a.
