A sample of hydrogen is collected in a flask over water. The partial pressures are 736 torr for H2 and 22 torr for H2O. What total pressure is exerted by the mixture of gases?

The total pressure exerted by the mixture of gases is 758 Torr.

Explanation:

Dalton's law of partial pressure is used to determine the total pressure exerted by mixture of gases. Also if we know the total pressure and the partial pressure of N-1 gases for mixture of N gases, then we can determine the partial pressure for the Nth gas.

So as per that law, the total pressure of any mixture of gases is equal to the sum of the partial pressure of individual gases. As partial pressure is the measure or the ability of each gas to produce pressure in a given volume, so the sum of those partial pressure will give the total pressure present in the gas mixture.

As the partial pressure of H₂ gas is given as 736 Torr and the partial pressure of H₂O is given as 22 Torr, the total pressure will be equal to the sum of those two pressures.

Total pressure = 736 + 22 = 758 Torr.

So, the total pressure exerted by the mixture of gases is 758 Torr.

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.
