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?
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?
A:sugar (C12H22O11)
B:KNO3
C:Ce2(SO4)3
D:KCl
What effects will dissolving sugar in water have on the resulting solution?
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
