In an exothermic reaction, the amount of energy required to break the attractions among the solute particles and among the solvent particles is
What is less than the energy released as attractions form between solute and solvent particles.

All materials that are considered to be insoluble will dissolve in a solvent to a very small extent. Would the rate of the dissolving of a rock in a streambed be increased by moving the rocking to a faster-moving current, reducing the exposure of the rock to the water, or moving the rock to warmer water?
What is reducing the exposure of the rock to the water.
100
To calculate the molarity of a solution, you need to know the moles of solute and the
What is liters of the solution

The maximum amount of a solute that will dissolve in a certain amount of solvent at a given temperature is that solute's what?
What is solubility
300
This solution contains as much solute as the solvent can normally hold at a given temperature.
What is saturated solution
300
These have a PH between 7 and 14.
What is a base

One way to determine the degree of saturation of a solid-liquid solution is to drop a crystal of the solute into the solution. If the crystal sits at the ottom of the container, the solution is
What is saturated.

A solution that contains more solute than it would normally hold at that temperature is said to be
What is supersaturated
500
The chemical reaction that releases energy to its surroundings
What is exothermic reaction
