When scientists say that a theory can never be proven, what are they actually saying? there is no way to test the accuracy of a theory. theories should not be used to make predictions. theories do not need to be tested or challenged. it is always possible for new data to contradict a theory.

Some molecular compounds, such as hcl, ionize completely in solution. for molecular compounds such as h2co3, most molecules do not ionize in solution. which describes the properties of these two solutes? a. hcl and h2co3 have the same effect on the properties of the solution. b. hcl raises the freezing point of water more than h2co3 does. c. hcl raises the boiling point of water more than h2co3 does.
