Why does a supersaturated solution is unstable and likely to have the solute come rapidly out of solution when it is shaken or disturbed?
A supersaturated solution contains more solute than can typically be dissolved at a given temperature, creating a state of instability. When the solution is shaken or disturbed, it introduces energy that disrupts this delicate balance, allowing solute particles to begin forming crystals or precipitating out of solution. This process occurs rapidly because the excess solute is no longer supported by the solvent's capacity, leading to a sudden release of solute. Thus, the disturbance triggers the crystallization process, causing the solute to come out of solution quickly.
What is relation between hydration energy lattice energy and enthalpy of solution?
The enthalpy of solution is the sum of the lattice energy (energy required to break apart the crystal lattice) and the hydration energy (energy released when ions are solvated by water). If the final enthalpy of solution is negative, it indicates that the overall process is exothermic and favors dissolution in water. Conversely, a positive enthalpy of solution implies that the process is endothermic and less likely to occur spontaneously.
What term describes a solution that contains the maximum amount of soluteit can hold?
A solution that has the maximum amount of solute dissolved at that temperature is known as a saturated solution.However it is possible to prepare a super saturated solution by heating the solution slightly, dissolving the maximum amount of solute and then carefully cooling the solution. Generally the super saturated solution is unstable and the excess solute will precipitate out if given the energy to do so.A common super saturated solution is a sugar solution. Sugar is added to water and the solution is heated and then carefully cooled. The solution can form a glass like solid called "toffee" rather than crystals of sugar.
Which denotes the change in energy during a dissolution process?
The change in energy during a dissolution process is called heat of solution. It represents the overall amount of energy absorbed or released when a solute dissolves in a solvent.
The heat energy absorbed or released when a specific amount of solute dissolves in a solvent is the?
The heat energy absorbed or released when a specific amount of solute dissolves in a solvent is called the heat of solution or enthalpy of solution. It represents the overall energy change associated with the dissolution process.
What solution is most likely to produce crystals if it's disturbed?
A supersaturated solution is most likely to produce crystals if disturbed, as the excess solute in the solution will start to come out of the solution and form crystal structures. Disturbing the solution can provide the necessary energy for the crystallization process to begin.
A solution in which more solute can dissolve at a given pressure and temperature may best be called?
supersaturated

What form of energy is observed when a spring is squashed?
When a spring is squashed, the energy observed is potential mechanical energy. This energy is stored in the spring as the deformation causes a change in its shape, which can be released as kinetic energy when the spring recoils back to its original position.

What is the overall energy change that occurs when a solution forms?
The overall energy change that occurs when a solution forms is the sum of the energy required to break the solute-solute and solvent-solvent interactions (endothermic process), and the energy released when solute-solvent interactions are formed (exothermic process). This results in either an endothermic or exothermic process, depending on the relative magnitudes of these interactions.

The change in energy during a dissolution process is called heat of solution. It represents the overall amount of energy absorbed or released when a solute dissolves in a solvent.
The heat energy absorbed or released when a specific amount of solute dissolves in a solvent is the?
The heat energy absorbed or released when a specific amount of solute dissolves in a solvent is called the heat of solution or enthalpy of solution. It represents the overall energy change associated with the dissolution process.
What is endothermic change?
endothermic change is a change, in which heat from outside is observed by reactants, leaving the surrounding cooler. Examples are evaporation of water, alcohol and dissolving glucose in water.
A beaker contains a solution. A single crystal added to the solution . Immeditely crystals from the solution?
When a single crystal is added to the solution, it can serve as a nucleation site, prompting the dissolved substances in the solution to begin crystallizing around it. This process occurs because the presence of the crystal lowers the energy barrier for crystallization, allowing solute particles to aggregate and form solid crystals. As a result, more crystals may precipitate out of the solution, leading to an observable increase in solid material. This phenomenon is commonly seen in supersaturated solutions.
How does renewable energy work as a solution?
Renewable energy prevents green house effect, air pollution and climate change. It is achieving sustainability, energy and food security.
