What happens to sodium chloride when it dissolves in water? a. electrons are transferred from sodium atoms to chlorine atoms, forming positive and negative ions. b. each sodium ion pairs with a chloride ion, and the pair of ions is surrounded by water molecules. c. the water molecules attract both the sodium ions and the chloride ions, pulling them together. d. the sodium ions are separated from the chloride ions, and both dissolve separately into the water.

D. The sodium ions are separated from the chloride ions, and both dissolve separately into the water.

Explanation:

When sodium chloride is dissolved in water, the polar water molecules are able to work their way in between the individual ions in the lattice. The water molecules surround the negative chloride ions and positive sodium ions and pull them away into the solution. This process is called dissociation.

In other words, In water, the sodium ions become attracted to the negatively-charged oxygen end of the water molecule, and the chloride to the positively-charged hydrogen side, which allows the two ions to become separated, hence dissolve.

the answer is:  

he is voicing feelings shared by all humans regardless of race.

in paul laurence dunbar's poem "we wear the mask," he replicates the words mask and we to emphasize how people in general -not just black americans- hide their true feelings. he suggests the masks cover people's faces and eyes, which are the main parts that display their emotions. he also thinks people's pain conceal behind those masks, so that they cannot see reality and nobody is able to see one another's sorrow.
