Which separation method would be most successful in separating the components of a homogeneous mixture?

a) screening
b) evaporation
c) centrifugation
d) magnetic separation

Option (B) is the correct answer.

Explanation:

When a liquid changes into vapors or gas then this process of change is known as evaporation.

A mixture in which solute particles completely dissolve in even composition throughout the solvent then it is known as homogeneous mixture.

For example, when salt is dissolved in water then upon heating it water can be evaporated and crystals of sodium chloride can be obtained.

Whereas screening method is used in the discovery of a drug and it a scientific experimentation method.

When particles of a mixture are separated by spinning then this process is known as centrifugation.

When a magnetic force is used to separate magnetic particles present in a mixture then this process is known as magnetic separation.

Thus, we can conclude that evaporation is the separation method would be most successful in separating the components of a homogeneous mixture.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
