Question

when you think about how you can clean oil off of birds and other animals, you should now know that water is not the answer. water is a polar molecule that can dissolve other polar substances. oil, on the other hand, is usually made up of nonpolar molecules. this does not mean that there is no substance that can dissolve oil. why do the molecules shown below look so colorful? based on the images below, try to deduce a principle that can help determine which substances can dissolve in which. select all that apply. polar substances dissolve in nonpolar substances. nonpolar substances dissolve in polar substances. polar substances dissolve in polar substances. nonpolar substances dissolve in nonpolar substances. solubility is unpredictable.

Explanation:

The principle in chemistry is that "like dissolves like". Polar substances have regions of partial positive and negative charges due to differences in electronegativity between atoms in the molecule. Non - polar substances have an even distribution of electron density. When a polar substance interacts with another polar substance, the positive part of one polar molecule can interact with the negative part of another polar molecule (through dipole - dipole interactions). Similarly, non - polar substances interact with non - polar substances through London dispersion forces. Polar and non - polar substances do not have compatible intermolecular forces for dissolution. For example, water (polar) and oil (non - polar) do not mix.

Answer:

C. Polar substances dissolve in polar substances, D. Nonpolar substances dissolve in nonpolar substances.
