A solution contains 0.010 M F− and 0.010 M CO32−. If Mg2+ is slowly added to the solution, which ion will precipitate first? What is the maximum concentration of Mg2+ that can be used to selectively precipitate out one metal ion, leaving the other ion in solution? The Ksp of MgF2 is 5.0x10−9 and the Ksp of MgCO3 is 5.0x10−8.

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
