2 -The following hypothetical chemical reaction illustrates the collision of the molecules of two gases‚ A2 and B2‚ to form another compound of AB. - Furthermore‚ the colliding species must be oriented in a manner favorable to the necessary rearrangement of atoms and electrons. Thus‚ according to the collision theory‚ the rate at which a chemical reaction proceeds is equal to the frequency of effective collisions. Because atomic or molecular frequencies of collisions can be calculated with some

to senior camp‚ friendships grew more and more complex. I found myself having to choose between girls in my bunk. Senior camp‚ the oldest age group‚ has many differences and privileges in comparison to the younger age groups. This includes the rearrangement of groups/bunks of girls. While I still had some of my close friends in this new cabin‚ there were two other girls named Jess and Dana who I didn’t particularly like. In fact‚ most of the senior campers didn’t love them.

The reaction order‚ based on the rate law‚ was first order with respect to crystal violet and second order with respect to OH-. The rate law was as follows: Rate law = k [CV]1[OH-]1 where k equaled 2.61. In order to determine the reaction order with respect to crystal violet‚ the graph that described the relationship between ln[CV] and time (seconds) was Figure 2. Not only did Figure 2 generate a more linear relationship‚ but it had the highest R2 value of 0.992 than ([CV] versus time) and ([1/CV]

Some figures of speech in the wasteland Figures of speech comprise two main categories. One category twists the meaning of words to wrest a new non-literal meaning from words that‚ when phrased together‚ have a very different literal meaning‚ as in the idiomatic figure of speech‚ "He died from laughter." Literally‚ this means a man met his demise due to laughter. Figuratively (i.e.‚ non-literally)‚ this means he laughed with vigor for a long time. Figures of speech that twist meaning are classified

Biodegradation OF Xenobiotics . OVERVIEW Microorganisms play an important role in the removal of synthetic organic compounds from the environment. This chapter gives an overview of the evolution of biodegradation pathways and describes the strategies that microorganisms have evolved to transform important molecular structures. The actual effectiveness of biodegradation in the environment is determined by the bioavailability of the

In the words of Etzioni “There is no room for initiative creativity‚ or even elementary rearrangements” (280).

because heat and bubbles are produced‚ and carbon was separated from the other substances. On the other hand‚ physical reaction only does macroscopic changes to the matter‚ for example‚ altering the shape‚ and painting the matter. There is not rearrangement of atoms in a physical change. Only a few properties change during a physical reaction‚ and they are mostly easy to reverse. One example of a physical change is mixing salt and water together. Although there is not a change in its appearance as

Experiment 1: Preparation of 1-Bromobutane and Reactivity of Alkyl Halides Objective: The purpose of this lab is to prepare 1-bromobutane from 1-butanol in an acid-catalyzed substitution reaction. While the reaction would be expected to occur as SN2 due to the primary nature of the substrate‚ because H2SO4 is used as a solvent‚ the conditions are very polar and the reaction can proceed via an SN1 reaction. The main objective is to obtain test results to determine the mechanism of the reaction
