1. What was your hypothesis?
2. Plot your data as drops of ascorbic acid vs. time.
3. As the concentration of ascorbic acid was increased, did the rate of the formation of the iodine starch complex
increase or decrease? Explain your answer in terms of the chemical reactions involved.
4. Was your hypothesis correct?
5. Make a general rule about the effects of concentration of reactants on reaction rates.
6. For practice, the molecular formula for ascorbic acid is C6H806, and you used 6 g in this experiment, calculate the
molarity of the ascorbic acid. Now calculate the concentration in moles per drop (assume 1 mL = 20 drops).

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:

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

1. they vary with a higher number because boiling is way hotter than melting

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
