What else can I help you with?
Does diffusion ever stop?
Diffusion will continue as long as there is a concentration gradient present. Once equilibrium is reached and the concentrations are equal throughout, diffusion will stop.
When does an equilibrium occur?
An equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time. Equilibrium can only be reached in a closed system under certain conditions, such as constant temperature and pressure.
A dynamic equilibrium is reached when hydrogen cyanide acid is dissolved in water Which species is present in the highest concentration in this solution?
C2H3O2-(aq) H+(aq) H3O+(aq) OH-(aq) HCN(aq)Those are the choices that could be given, but the answer is HCN. It can't be H+ or OH- because the water is de-ionized and H3O+ is not possible.
How does the time it takes for equilibrium to be reached affected by temperature increases?
An increase in temperature can generally speed up the time it takes for equilibrium to be reached in a chemical reaction. This is because higher temperatures provide more energy to the reactant molecules, increasing their kinetic energy and collision frequency, which in turn accelerates the rate of the reaction towards equilibrium.
How do you know that thermal equilibrium has been reached between two objects?
Thermal equilibrium between two objects is reached when they have the same temperature and there is no net flow of heat between them. This can be determined by measuring their temperatures over time and observing that they remain constant and equal.
What is solubility equilibrium?
Equilibrium solubility is how much of a certain solute is in solution when the system has reached equilibrium. For example, when something like silver chloride (AgCl) is placed in water, none of it goes into solution. But given some time, an equilibrium will be reached where a small amount of AgCl is in solution and is in equilibrium with the insoluble AgCl.
Is reached when the concentration of the solute is the same throughout a solution?
dynamic equilibrium
Does diffusion ever stop?
Diffusion will continue as long as there is a concentration gradient present. Once equilibrium is reached and the concentrations are equal throughout, diffusion will stop.
When the particles are the same throughout the system?
Equilibrium is reached, the solution is isotonic.
When has a solution reached equilibrium?
Something is in "equilibrium" when it is in a state of perfect balance or rest. All forces acting on it are equal and opposite. It is in a "minimum" energy state.
Is The substances of a solution are evenly distributed?
Of course they. If not, they would not be "in solution".If substances of a solution are evenly distributed then they have reached equilibrium.
What is reached when the number of molecules crossing the membrane is the same in both directions?
When the number of molecules crossing the membrane is the same in both directions, equilibrium is reached. This means that a state of balance has been achieved, where there is no net movement of molecules across the membrane.
What is the difference between a saturated solution and a super-saturated solution?
A super saturated solution is unstable, and wants to precipitate some solute to regain a stable situation. Dissolve something in water at a high temperature in a perfectly clean glass container, until no more dissolves. Cool slowly and the solution becomes unstable because it holds more in solution than is normal at equilibrium at that lower temperature. It is super saturated. A tiny speck of dust or even agitation can provide conditions where the excess can precipitate out as a solid particles in suspension, until the equilibrium concentration of solution is reached, but with clouds of precipitate in there.

What is reached when molecules are equally distributed?
an equilibrium
When equilibrium is reached will the fluid levels be the same as they are now?
When equilibrium is reached, the fluid levels may not necessarily be the same as they are now. Equilibrium refers to a state where the forces or concentrations are balanced, leading to no net change in the system. However, the final fluid levels depend on factors such as the initial conditions and the specific processes involved in reaching that equilibrium. Thus, while the system will stabilize, the fluid levels could differ from their initial values.
How does a system respond to change once it has reached equilibrium?
At equilibrium its not changing (any more).
