Answer:

Incomplete precipitation of barium sulfate

The student has precipitated and digested the barium sulfate on his/her side. But on the addition of BaCl_2 in the solution, the solution become cloudy. This happened because incomplete precipitation of barium sulfate by the student. When BaCl_2 is added, there are still sulfate ions present in the solution with combines with BaCl_2 and forms BaSO_4 and the formation of this precipitate makes the solution cloudy.

Describe the difference between gravitational force and strong nuclear force
arsen [322]

Gravitational force is much weaker, because it is the force of gravity, or the force that makes smaller objects be pulled towards a much bigger one with a certain amount of force.

Now strong nuclear force, which is very strong, keeps the atomic particles in an atom from separating, and the reason it is so powerful is because the particles in an atom repel each other and this force keeps them from doing .that
