Question

1. a soap micelle can form when molecules are dissolved in water because

polar regions of the soap molecule experience electrical repulsion from
the polar water molecules.
polar regions of the soap molecule experience electrical attraction to the
nonpolar regions of other soap molecules.
nonpolar regions of the soap molecule experience electrical attraction to
the polar water molecules.
polar regions of the soap molecule experience electrical attraction to the
polar water molecules.

Explanation:

Soap molecules have a polar (hydrophilic) head and a non - polar (hydrophobic) tail. Water is a polar molecule. According to the principle of "like dissolves like", the polar regions of the soap molecule (hydrophilic heads) are attracted to the polar water molecules (electrical attraction due to the polarity of both). The non - polar tails of the soap molecules cluster together away from water.

Answer:

polar regions of the soap molecule experience electrical attraction to the polar water molecules.
