Answer:
Approximately .
Step-by-step explanation:
Remark: this approach make use of the fact that in the original solution, the concentration of and
are equal.
Since is a salt soluble in water. Once in water, it would readily ionize to give
and
ions.
Assume that the and
ions in this solution did not disintegrate at all. The solution would contain:
of
, and
of
from
of
.
Accordingly, the concentration of and
would be:
.
.
In other words, in this buffer solution, the initial concentration of the weak acid is the same as that of its conjugate base,
.
Hence, once in equilibrium, the of this buffer solution would be the same as the
of
.

Answer: There is a probability of 0.05 that there is neither truck is available.
Step-by-step explanation:
Since we have given that
Probability that the first truck is available = 0.75
Probability that the second truck is available = 0.50
Probability that both trucks are available = 0.30
So, probability that either first truck or second truck is available is given by
We need to find the probability that neither truck is available.
so, P(A∪B)'=1-P(A∪B)
Hence, there is a probability of 0.05 that there is neither truck is available.
