Answer:
The eccentricity of the ellipse is 0.252.
Explanation:
The eccentricity of an ellipse (

(1)
Where:
- Distance between the foci, dimensionless.
- Length of the major axis, dimensionless.
If we know that
and
, then the eccentricity of the ellipse is:


The eccentricity of the ellipse is 0.252.
Answer: The values for Ka and Kb for the species in solution must be known before a prediction can be made
Explanation:
1. If Ka is greater than Kb, the salt solution is acidic
2. If Ka is lesser than Kb, the salt solution is basic
3. If Ka is equal to Kb, the salt solution is acidic
