Sodium chloride (naci) dissolves in water because water molecules
a. lose electrons
b. have a ph near 7
c. have a high specific heat
d. are polar

The correct answer is D. Are polar.

Explanation:

When NaCl is dissolved in water it dissociates and each part of the molecule is surrounded by the water in the correct dipole. Na (+) is surrounded by the oxygen part of water, without it dissolving itself, and Cl (-) is surrounded by the hydrogens. NaCl is a salt and therefore it dissociates when in contact with water.

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
