An ionic solid is placed in a beaker of water. which of the following occurs when there is a strong attraction between the solute and the solvent?
a. the solute melts.
b. the solute dissolves.
c. the solute remains intact.
d. the solute reacts to form a precipitate.

Infants born with severe respiratory problems are sometimes given liquid ventilation: they breathe a liquid that can dissolve more oxygen than air can hold. one of these liquids is a fluorinated compound, cf3(cf2)7br. the solubility of oxygen in this liquid is 66 mlo2 per 100 ml liquid. in contrast, air is 21 % oxygen by volume. calculate the moles of o2 present in an infant's lungs (volume: 12 ml ) if the infant takes a full breath of air. assume a pressure of 1 atm in the lungs.

After cloud droplets form, what must happen to them for precipitation to occur?

What pressure will be exerted by 0.675 moles of a gas at 25*c if it is in a 0.750-l container?
