The molecules that make up soap have a region that contains polar covalent bonds and a region that contains nonpolar covalent bonds. How does this property explain the ability of soap molecules to help remove oils from your skin when you wash?

Explanation:

The cleansing action of soaps is predicated on the nature of soaps as we have it.

A soap has the ability to remove dirt from materials. The cleansing action of a soap is related to the structure of its molecule. A molecule of soap has dual structure with polar head that is water loving and a long hydrocarbon tail which is hydrophobic. The structure enables soap molecules to emulsify an organic dirt present on a fabric in water. The soap causes the suspension of tiny oil droplets in the aqueous medium.

Answer : option a) 84explanation :

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.
