Question #4a5bb + Example - Socratic
See this old answer for examples of supersaturated solutions. Examples of supersaturated solutions appear in the link. Saturated solutions contain the same amount of solute that would be in equilibrium with undissolved solute. Any mixture from which a solute has precipitated gives a saturated solution with respect to that solute. Why, because there is equilibrium between undissolved solute and ...

Question #43f8e - Socratic
LeChatelier's Principle => If a stress is applied to a reaction, the reaction will shift away from the applied stress and establish a new equilibrium. Three 'stress' factors affect stability of an equilibrium ... 1. Changes in concentration of reactants or products, 2. Temperature changes, and 3. Pressure-Volume effects (Boyle's Law) While considering concentration effects, it is useful to ...

A balanced lever has two weights on it, the first with mass 3 kg and ...
21m We apply the second condition for static equilibrium which states that the result torque (moments) must be zero, ie. sum vectau=0, where vectau=vecrxxvecF is the cross product of the position vector from the axis of rotation (fulcrum) to the applied force and the applied force. So in this case : r_1F_1-r_2F_2=0 therefore (7xx3g)- (r_2xx1g)=0 thereforer_2= (7xx3xx9.8)/ (1xx9.8)=21m.

The surface's coefficient of static friction, in this case, will be 0.0051, approximately. Since the object is lying still on the surface, it is in equilibrium and, therefore, the net force in it must equal zero: F_N = 0. (1) Since it is placed by a horizontal spring, the friction force, f, will also be in that direction, opposing to the spring's force. Now, since the displacement Deltax = 1m ...

Of course in aqueous solution (and most of them are supplied as aqueous solutions), the following equilibrium occurs: HX (aq) + H_2O (l) rightleftharpoonsH_3O^ (+) + X^- For stronger acids, the equilibrium lies to the RIGHT; for weaker acids the equilibrium lies to the LEFT as we face the page.

How do we assess the strength of an acid? - Socratic
Of course, tunnelling, proton transfer, is more likely in a cluster of water molecules, so the analogy might not be particularly apt in that there is definite transfer of a ball in a maul, but a charge in a water cluster is conceivably tunnelled. The same applies to the transfer of an hydroxide ion. For this reason both #H^+"/"H_3O^+# and #HO^-# have substantial mobility in aqueous solution.

Question #8da2c + Example - Socratic
A Central Force is a special kind of force that originates from a single point in space. A particle under the influence of this force will have its force vector always directed towards that origin point and the magnitude of this force will only depend on the distance of the object from the origin. It is convenient to work with polar coordinates with such forces, placing the source of the force ...

Question #1671c - Socratic
Here's what I got. You know that at a given temperature, the equilibrium constant that describes this equilibrium "AB"_ ( (g)) rightleftharpoons "A"_ ( (g)) + "B"_ ( (g)) is equal to 4 times the total pressure in the reaction vessel once equilibrium is established.
