Answer:
2.85 rad/s
Explanation:
5 cm = 0.05 m
20 g = 0.02 kg
When dropping the 2nd object at a distance of 0.05 m from the center of mass, its corrected moments of inertia is:

So the total moment of inertia of the system of 2 objects after the drop is:

From here we can apply the law of angular momentum conservation to calculate the post angular speed

Is there any chemical names listed ?
