Answer:
185.1 m/s
Explanation:
The average speed of an object is a scalar quantity telling us how fast is the object moving over a certain distance.
This quantity is calculated as
where
d is the distance covered by the object
t is the time elapsed
v is the average speed
In this problem we have:
d = 1500.0 m is the distance covered by Ken
t = 8.1018 s is the time taken
Substituting into the formula, we find the average speed:
Answer:
pKa = 4.89.
Explanation:
We can solve this problem by using the <em>Henderson-Hasselbach equation</em>, which states:
pH = pKa + log
In this case [A⁻] is the concentration of sodium benzoate and [HA] is the concentration of benzoic acid.
We <u>input the given data</u>:
4.63 = pKa + log
And <u>solve for pKa</u>:
pKa = 4.89
