Test 3 CHEM 2511 Summer 2018 13) Which of the following mass spectra shows the presence of bromine in a compound? m/e 14) Which one of the following compounds is consistent with the following spectra below? Solution Answer 13: Bromine has twi isotopes: 79 Br and 81 Br. The isotopic abundance of both isotopes are almost equal i.e about 1:1. So, a compound having a Bromine group shows M + as well as (M+2) + peak. The given spectras show that option (D) is having M + as well as (M+2) + peak. Further, the molecular ion peak must have value greater than the molecular weight of Bromine (79) so, answer is (D). Answer 14: The correct answer is (C). Since in (c) the three H of benzene rings are equivalent while in other options they are not equivalent. Moreover in (d) there are five protons. Overall, structure (c) justifies the 9 (METHYL protons) and 3 (AROMATIC potons). .

Sustainability is an important ethical and environmental issue in purchasing. Describe one material, product, or service that can contribute to sustainability in a project you have been involved with, or in your current organization. Describe how these decisions enable the organization to avoid violations in terms of environmental issues Solution Sustainable Business Practices Introduction: The Role of Business Economic structures and policies create the context for throughput, but it is individual business operations that are responsible for the actual throughput activities in the production of goods and services. The specific technologies they use have a significant impact on the amount and types of materials that go through the production cycle of extraction, manufacture, use and waste. In the past, the impact of various technologies on the environment was not a significant issue for business planning and operation. The effects of burning coals were too obvious to ignore in the late 19th and early 20th centuries, but even British royalty could not exert enough authority to reduce the pollution created. Concerns for the environmental impact of business activities arouse in earnest in the latter part of the 20th century with the evidence of chemical pollution, a variety of environmentally significant industrial accidents, opposition of indigenous peoples to logging and mining operations, and the discovery of human impacts on global systems such as the atmospheric ozone layer and climate (see Areas of Concern). The accumulating evidence of serious environmental and human health effects triggered citizen protests, and led governments to begin exerting influence on businesses to clean up their act. Environmental concerns arose for individual nations (eg. with the US establishing the Environmental Protection Agency in 1969) and within the United Nations (eg. UNESCO .

Thank you. Let Phi: R rightarrow S be a surjective homomorphism from the ring R to the ring S. Prove that if T is a subring of R, then the set W= {b S such that b = Phi(c) for some c T} is a subring of S. [Be specific of how and where you use that T is a subring of R.] Solution for this we only have to prove that there exist identity if b is in W then tere is a element -b in W such that b - b = 0 so if phi(c) = b then phi(-c) = -b where c and -c are in T since T is a subring since phi is homeomorphism. now if b and c are in W then there are d and f in T such that phi ( d) =b and phi (f) = c then phi (df) = phi(d) phi(f) = bc in W so W is a ring and since it is subset of S so it is subring of S .

class is intro to computers - studying environmental studies and law eventually to become environmental lawyer. ? I need help with is - what areas of computing will be most beneficial for me to understand in realtionship to my career and if i work from home how will understanding computer hardware and software help me when communicating in groups and other countries? Solution The Internet also alters our perception of duration. Sometimes, when working on an obstinately analog process such as the actual fabrication of an object, the internalized shadow of fleeting Internet time in our consciousness makes us perceive how the inevitable delays inherent in the fashioning of things (in all their messy \'thingness\') ground us into appreciating the rhythms of the real world. In this way, the Internet\'s pervasive co-presence with real world processes, ends up reminding us of the fact that our experience of duration is now a layered thing. We now have more than one clock, running in more than one direction, at more than one speeds. .

Name the three halogens. ne on ne ion Solution Sodium is often present as an impurity. In most of the flame test for other elements sodium impurities would give a yellow colour to the flame. However presence of Sodium as a main component of the solution and as an impurity can be easily determined by observing the intensity of the flame. The presence of Sodium in bulk amount in a mixture will give an intense bright Yellow colour to the flame. But Sodium impurities only gives a dull yellow colour. Use of a Cobalt glass can filter the yellow colour produced by sodium impurity from the flame test. .

Cloud Computing Theory and Practice chapter 2 problem 7 Tuple-spaces can be thought of as an implementation of a distributed shared- memory. Tuple-spaces have been developed for many programming languages including Java, Lisp, Python, Prolog, Smalltalk, and Tcl. Explain briefly how tuple spaces work. How secure and scalable are the tuple spaces you are familiar with, e.g., JavaSpaces? Solution Definition : A tuple space is an execution of the associative memory model for distributed/parallel computing. It offers a library of tuples, which can be accessed simultaneously. Tuples are terms with zero or more arguments and a key. Explanation: The collection of tuples supports some basic operations, such as adding a tuple to the space (write) and removing a tuple from the space (take). The tuple collection is kept and managed over a network of multiple tuple space servers. A tuple space is, as its name suggests, a place where processes can put, read, and take tuples, which are in turn just sequences of values is a tuple made up of a string, an integer, and a floating-point number; a tuple space can contain zero or more copies of that tuple, or of tuples containing other types of values, simple or complex. A process puts something in tuple space with put(value, value, ...). It can take something out with take(...), or copy something (leaving the original in tuple space) with copy(...). The arguments to take(...) and copy(...) are either actual values, or variables with specific types; values match themselves, while types match things of that type. .

Clint is Marilyn\'s supervisor. Marilyn is a dedicated part-time employee who is known for taking on responsibility. Clint joked with his colleague that he could trick Marilyn into completing a project for him so that he could take a long weekend. Clint told Marilyn that only she had the skills and conscientiousness to complete the project properly and on target and, further, that it would be a big favor to him if she would accept the challenge. Marilyn agreed to do the project. However, when she could not reach Clint over the weekend to obtain some additional explanation that was critical to completing the project, she left it incomplete. Clint placed full responsibility for the failure squarely on Marilyn, who now feels that her stellar record has a big blemish. Marilyn is lamenting all this, and after giving up her entire weekend with no extra pay, to boot. Solution (1) Clint broke the rule of regulations which was addition of extra explanation which was going beyond the topic. (2) Marlyn broke the rules of regulation which was failur to complete the project on time. (3) The common mistakes made by both Clint and Marlyn is that lack of skills utilisation over the work allocated. (4) Marlyn could recover from the mistakes commited from her by making correct decision using complete common sense and correct precsion in time. .

Choose one of the transition or inner transition metals from the periodic table. I choose Iron (Fe) Using your book (Chapter 23 may be very useful) and Internet resources, discuss why your transition metal and their compounds display a variety of color. Be sure to include in your discussion, important oxidation states, the electron configuration and how the d-electrons are involved. How can you include the electromagnetic spectrum and the nature of light into your discussion? How are energy and wavelength related? Use your knowledge of the emission and absorption of light in your discussion. Remember to cite your sources in APA style. Solution Transition metal Fe Electronic configuration : [Ar] 3d6 4s2 So, it has partially filled d-orbital. Fe can absorb light of different wavelength and causes excitation of d-electrons. While returning (relaxing) they release the absorbed light in the visible region and wavelength and thus we see colors. Depending upon the wavelength of light used for the absorption, the electrons may get excited to different possible energy levels and thus variable colors are seen for transition metals. Energy is related to inverse of wavelength of light So, as lower energy of light would result in greater wavelength color emission and vice versa. .

CHEM 464 â€“ Biochemistry I Summer 2018 Homework 4: Upload file(s) to D2L by 6/24/18 1. Each of the following reagents or conditions will denature a protein. For each, describe in one or two sentences what the reagent/condition does to destroy native protein structure. a. Urea b. High-temperature c. Low pH Solution NH2 and carbonyl groups of urea make hydrogen bonding with the hydrogen bonding sites in the protein thus disrupts intramolecular hydrogen bonding which leads to denaturation of protein molecule. Due to increase in temperature kinetic energy of the molecule increases which makes molecule to vibrate rapidly and violently, due to which the hydrogen bonds are disrupted. Hence denature the protein. Low pH increase the H+ ion concentration. Which protonates the hydrogen bonding sites hence no intramolecular hydrogen bonding takes place which leads to denaturation of protein. .
