Determine the molecular formulas to which the following empirical formulas and molar masses pertain.
a. SNH (188.35 g/mol)
b. NPC12 (347.64 g/mol)
c. CoC404 (341.94 g/mol)
d. SN (184.32 g/mol)

What happens when the temperature of a solution increases?

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.

How is energy related to the change of state represented by the model? atoms gain energy as a solid changes to a liquid. atoms gain energy as a solid changes to a gas. atoms lose energy as a solid changes to a liquid. atoms lose energy as a solid changes to a gas.
