6) At home, you keep adding sugar to ice water while stirring. Which of the following is true? A) The sugar will eventually not dissolve since the water will eventually reach a limit to how much solute will dissolve, regardless of how much you're stirring.

B) As long as you keep stirring, the sugar will always dissolve, regardless of how much water is in the glass.

C) The ice will eventually melt, but if you add more ice while adding more sugar, the sugar will always dissolve as long as you keep stirring and adding more sugar.

D) If you stop stirring, a supersaturated solution will be created after a minute or two.

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.
