Achemical is placed in a beaker containing 20 g of soil and 500 ml of water. at equilibrium, the chemical is found in the soil ast a concentration of 100 mg . kg-1 of soil. the equilibrium concentration of this same chemical in the water is 250 what is the partition coefficient for this chemical on this soil?400 mg kg-1/mg l-1

Kd = 400 (mg/kg)/(mg/L)

Explanation:

Assume that the units for the concentration of the chemical in water is μg/L

Convert units of concentration of chemical in water to mg/L

Cw = 250 μg/L

Here, the concentration of chemical in water is Cw

1 mg = 11000 μg

Cw = 250 x 10⁻³mg/L

Calculate the partition coefficient for the chemical in soil as follows

Kd = Cs/Cw

Here, the partition coefficient is Kd, the concentration on the soil at equilibrium is Cs and the concentration of chemical in water at equilibrium is Cw.

Substitute 250 x 10⁻³ mg/L for Cw and 1000 mg/kg for Cs

Kd = 100 (mg/kg))/ (250 x 10⁻³)(mg/L)

Kd = 400 (mg/kg)/(mg/L)

according to kinetic-molecular theory, the following would not be considered an ideal gas:

a gas at very low volumes, when gas particles are very close together

a gas at very low temperatures, when gas particles have very little kinetic energy a gas

a gas with highly polar molecules that have very strong intermolecular forces

when—without warning—something provokes your anger, you may struggle not to succumb to it. since what typically makes you mad is feeling powerless in the face of what seems unfair, your anger is mostly an attempt at a “quick fix” to right the balance. it’s as though you’re raising a fist in protest, proclaiming that you’re not going to capitulate to such injustice.

there are, however, a multitude of problems related to this immediate, push-back reaction of anger. and probably the key one is that almost never does it resolve the issue that gave rise to it. such reactive anger is probably best understood as self-defeating. as david burns, the author of the seminal self- book feeling good, observes: if realistically, acting on your anger is to make any sense, it needs to meet two criteria—which, in almost every case, is frankly impossible. that is, your anger must:

be directed toward a person who has intentionally (and needlessly) behaved in a hurtful way toward you; and

be beneficial or advantageous to you (i.e., assist you in achieving a desired goal).

i think you’ll agree that only rarely can you claim that your anger is both warranted and , whether to yourself or the relationship.

so let me offer you a two-step alternative to abandoning your better judgment and giving in to the temptation of anger—one that should neutralize your anger in seconds. or, when you’re really angry, in minutes.

but keep in mind that you must really want to execute these steps, be sufficiently motivated to perform them. which means overcoming more unconscious resistance than you might ever have imagined. because there are many immediate “advantages” of anger that can interfere with your resolve, i’ll suggest a few of them that might interfere with your employing this powerful method to rid yourself of counter-productive anger.
