It is not possible to determine CD - 
is more or less soluble than as though they have a different Ksp values their molecular dissociation is also different and they may have a close solubility values.

Ksp = ![[A2+][B-]^2 = s \times (2s)^2 = 4s^3](https://tex.z-dn.net/?f=%5BA2%2B%5D%5BB-%5D%5E2%20%3D%20s%20%5Ctimes%20%282s%29%5E2%20%3D%204s%5E3)
Hence they can be directly compared by Ksp values, smaller the Ksp, smaller the solubility.

Hence, they can be directly compared by Ksp values, smaller the Ksp, smaller the solubility.
Your pattern of breathing increases, making it faster than usual, when you're exercising because you're pushing your body to work harder and speeding up your heart rate making you tired.
When you're resting your breathing pattern should be steady and normal since you aren't doing anything that requires lots of body work or something that would make you out of breath.
Hope this helps,
