Which of the following is not a postulate of the kinetic molecular theory? select one: a. gas particles have most of their mass concentrated in the nucleus of the atom. b. the moving particles undergo perfectly elastic collisions with the walls of the container. c. the forces of attraction and repulsion between the particles are insignificant. d. the average kinetic energy of the particles is directly proportional to the absolute temperature. e. all of the above are postulates of the kinetic molecular theory.

a. Gas particles have most of their mass concentrated in the nucleus of the atom

Explanation:

The main postulates of the molecular kinetic theory are:

A gas consists of a set of small particles that move with rectilinear motion and obey Newton's laws (this means that this theory doesn't divide the atom in a nucleus and electrons, this is why a. is not correct)

The molecules of a gas do not occupy volume (this is assumed because between the molecules of a gas is a lot of space).

Collisions between the molecules are perfectly elastic (this means that energy is not gained or lost during the crash).

There're no forces of attraction or repulsion between the molecules (because each molecule is "far" of the others).

The average kinetic energy of a molecule is (where T is the absolute temperature and k the Boltzmann constant. This means that kinetic energy is directly proportional to temperature).

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.

explanation:

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
