The following list contains some common polyatomic ions. Using the charge on these ions and the idea of valence, predict the formulas for the following: (aluminum nitrate)

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.
