1. Molten magnesium chloride is electrolyzed with a current of 12.5 A for 40 minutes. Calculate the volume (at 25 ° C and 1 atm) of chlorine that forms at the anode of the electrolytic cell. Also calculate the mass of aluminum that is deposited at the cathode of an electrolytic cell containing its salt in the molten state, when the same current is passed through the cell for 1.5 hours. 2. The boiling temperature of a cobalt (II) chloride solution is 100.5 ° C. Her density at 25 ° C is 1.235g / cm3 . Calculate the osmotic pressure of the solution at 25 ° C. [Keb = 0.515] 3. Calculate the volume of water needed to solubilize 0.05 g of cadmium hydroxide. [Kps = 5.27x10-15] 4. At 2.50 dm3 24.0 cm3 of an ammonia solution of pH = 10.85 are added 7.50% w / w hydrochloric acid solution (d = 1.015 g / cm3 ). Calculate the pH of the solution resulting. [Kb = 1.85x10-5] 5. An aqueous solution of the sodium salt of a monoprotic weak acid has pH = 10.20. Calculate the volume of gaseous hydrochloric acid (measured at c. n.) necessary to buffer a pH = 7.5 150.0 cm3 of the initial solution. [Ka HA = 1.5x10-7

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.
