Question

Below is a graph of measured atmospheric CO2 levels since 1980 (from globalchange.gov).  Based on these data, how has the solubility of CO2 in ocean water changed over this time period?

 

Group of answer choices

A:It is not possible to predict CO2 solubility changes based on these data.

B:CO2 solubility has decreased.

C:CO2 solubility has not changed.

D:CO2 solubility has increased.

 

According to this solubility graph, which solid's dissolving process is exothermic?

 

Group of answer choices

A:sugar (C12H22O11)

B:KNO3

C:Ce2(SO4)3

D:KCl

 

What effects will dissolving sugar in water have on the resulting solution?

Group of answer choices

A:Compared to pure water, the solution's freezing point will be lower and its boiling point will be higher

B:Compared to pure water, the solution's freezing point will be higher and its boiling point will be lower

C:Compared to pure water, the solution's freezing point will be lower and its boiling point will be lower

D:Compared to pure water, the solution's freezing point will be higher and its boiling point will be higher
