When you attempt to prepare sulfanilamide from this reagent, a polymeric product is produced after the addition of PCL5 in step one. So no, this is not typically a reaction used to prepare sulfanilamide.

A clean surface of pure uranium has a metallic appearance, as a steel.

This question is rather ambiguous, as the amount of impurity would need to be known (i.e. is it 99% pure? 95%? 80%? etc). As the level of impurity rises however, the melting point (freezing point) will drop.

Protactinium has a metallic appearance.
The fresh surface of pure plutonium is silvery.
