The substances that would dissolve in water and isopropanol would be polar substances. This is by the virtue like dissolves like. Water and isopropanol are polar solvents which would mean polar molecules would be dissolved in them. Polar molecules contains electrical poles which allows them to be dissolve into polar solvents.<span />
You would need instructions. Do it with science materials.

Answer:
This question appears incomplete
Explanation:
However, the chance of finding one isotope of an element is not the same for all elements because some elements/isotopes are more in abundance than some other elements/isotopes; for example the most abundant element on earth is nitrogen-14, hence the chances of finding nitrogen-14 in nature is higher the chances of finding any isotope of Xenon.
Also, while isotopes occur naturally, some do not. Hence, the chances of finding a naturally occurring isotopes (no matter how rare like Xenon-126) is higher than the chances of finding artificial radioisotopes like technetium-95 and promethium-146 (whose chances are zero because they cannot be found naturally occurring).
