Answer:
Explanation:
In this case, we have to remember the <u>relationship between the Ka value and the pH</u>. We can use the general reaction for any acid with his Ka value expression:
In the Ka expression, we have a<u> proportional relationship</u> between Ka and the concentration of . Therefore, if we have a higher Ka value we will have a smaller pH (lets keep in mind that with a higher
So, if we have to find the higher pH value we need to search the <u>smaller Ka value</u> in this case .

Answer:
Explanation:
The graduated cylinder contains of water
mL is a volume unit.
Water volume = 41.7 mL
The lead ball caused an increase of volume from 41.7 mL to 96.0 mL
The new volume is the lead ball volume plus the original water volume :
Final volume = Vlead ball+ Water original volume
This is actually true if we suppose that the lead ball is fully sunken in the water.
We always must consider that the volume difference is the volume that the sunken object is occupying in the water.
