Afictional company has been producing propene oxide, c3h6o, from propene, c3h6, with a 96.0% yield. the process requires the use of a compound called m-chloroperoxybenzoic acid, c7h5o3cl, which can be abbreviated as mcpba. the entire reaction takes place in the solvent dichloromethane, ch2cl2:
c3h6+c7h5o3clch2cl2−−−⟶96.0% yieldc3h6o+c7h5o2cl
the initial propene concentration in the solvent is 21.0 g/l.
consider the prices of the following substances.
substance price per unit unit
propene $10.97 kg
dichloromethane $2.12 l
mcpba $5.28 kg
propene oxide $258.25 kg
also consider that the cost of waste disposal is $5.00 per kilogram of propene oxide produced.
part a
a relatively simple way of estimating profit is to consider the the difference between the cost (the total spent on materials and waste disposal) and the earnings (the price at which the product can be sold).
calculate the profit from producing 43.00 kg of propene oxide.

alternative method
the company is developing a "greener" method of making propene oxide from propene using hydrogen peroxide, h2o2, in supercritical water with a vanadium catalyst. in the reaction 1.00 kg of vanadium catalyst and 32.0 kg of water are used for each kilogram of propene. 75 % of the vanadium catalyst can be collected and reused in a subsequent batch:
c3h6+h2o2v, h2o−−−⟶89.0% yieldc3h6o+h2o
consider the prices of the following substances.
substance price per unit unit
propene $10.97 kg
hydrogen peroxide $1.96 kg
vanadium catalyst $57.50 kg
supercritical water $1.85 kg
propene oxide $258.25 kg
there is virtually no waste produced with this green process and there is no waste disposal fee, but the yield is only 89.0%.
part b
calculate the profit from producing 43.00 kg of propene oxide by this alternative green process.

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.
