Which of the statements about the effect of solutes on solutions is true?
select one:
a. solutes raise the boiling point of a solvent.
b. solutes raise the freezing point of a solvent.
c. water with a solute dissolved in it will freeze at 0°c.
d. antifreeze boils at a lower temperature than pure water.

A) Solutes raise the boiling point of a solvent.

Explanation:

When the solutes are added into solvents boiling point of solvents increases.

Consider the example of NaCl in water:

The water boil when the molecules of water overcome the surrounding pressure and turn into gaseous phase.

But when we added the the salt it splits into the anion and cation and intermolecular forced between water molecules altered. The di pole is created one side becomes positive and other becomes negative. This di pole interaction is stronger than hydrogen bonding. So more energy in required to move the particles apart from each other.

Thus boiling point increases and compared to pure water.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
