...The following is a final business report about my company, and my feelings on the business project this semester. The name of my business is Bass and Treble Music Company. I chose Bass and Treble for the name of my business because, in music, there is a bass clef and treble clef. These two clefs are symbols used to show if the notes are in the lower or higher spectrum of music. I thought it would be clever to use something musical in the name for a music company. I am the owner of Bass and Treble Music Company. I am in charge of, basically, everything. I have to make sure the business is running smoothly, and all of my employees are working efficiently to make sure the customers are fully satisfied. I am also the person that verifies everything to make sure it is appropriate and ready for the public. For example, I have to approve all social media posts before they are actually posted, so that Bass and Treble is properly represented and shown to the public. Although I am the owner, I have the most responsibility because I have to approve everything first. There may be employees that run certain area of the business, but I am the one who must look over everything to let it go to the public. Bass and Treble is not selling a specific product. It is a music company that has a plethora of musical options for people to choose from. Bass and Treble offers music lessons, a range of music to buy, instruments, supplies for various instruments, and even a separate lodge for performances...

...U2 mod 1chem. Halogenoalkanes page1 of 4 Introduction Halogenoalkanes or alkyl halides are derivatives of alkanes. General formula = CnH2n+1X or simply R—X where R represents an alkyl group They can be classified as primary, secondary or tertiary alkyl halides. Primary alkyl halides have either 1 or no alkyl groups attached to the central carbon atom. Secondary alkyl halides have 2 alkyl groups (circled) attached to the central carbon atom. Tertiary alkyl halides have 3 alkyl groups (circled) attached to the central carbon atom Aryl halides are compounds in which the halogen atom is attached directly to the aromatic ring. U2 mod 1chem. Halogenoalkanes page2 of 4 Reactions of alkyl halides The point of attack would be the electron deficient carbon atom (due to the difference in electronegativity in the C-X bond) attached to the halogen atom , thus the attacking species would be a nucleophile. All reactions need the present of heat i.e. reflux 1. Alcohol formation (R represents any hydrocarbon chain) R—X + OH- R—OH + XPrimary and secondary alkyl halides undergo alkaline hydrolysis to the alcohol while tertiary alkyl halides can be hydrolysed by water. Aryl halides do not undergo hydrolysis except under VERY SEVERE conditions. Industrially chlorobenzene is reacted with NaOH(aq) at 360 °C at a high pressure then adding dilute HCl. 2.

...These recommendations document the von Baeyer system for naming polycyclic ring systems described in Rules A-31, A-32 and B-14 of the Nomenclature of Organic Chemistry, Sections A, B, C, D, E, F and H, 1979 and R-2.4.2 of A Guide to IUPAC Nomenclature of Organic Compounds, 1993 and extend the system to cover more complex cases. It provides guidance on the naming of ring systems which previously the rules did not cover. The method is to identify the main ring and main bridge which provide the basic bicyclic system and to number these atoms. Then all further bridges, whether or not they include additional atoms, are identified by indicating not only the number of atoms but also the two atoms to which the bridge is attached. The final name also indicates the number of rings and the total number of skeletal atoms in the ring system. Heteroatoms, unsaturation and substituents are indicated in the usual way. Preamble This system of naming polycyclic compounds was first developed for bicyclic compounds by von Baeyer (ref 1) and was extended to tricyclic systems by Buchner and Weigand (ref 2). Von Baeyer nomenclature was adopted by Patterson (ref 3) in his work for IUPAC on ring nomenclature which was used in the Ring Index (ref 4) and by the Chemical Abstracts Service Index Guide, Appendix IV, ¶ 155, 161, 184 (ref 5). IUPAC extended von Baeyer nomenclature in the current rules, see rules A-31, A-32 (hydrocarbons), B-14 (heterocyclic compounds) plus examples in B-6.1,...

...Biology From Wikipedia, the free encyclopedia For other uses, see Biology (disambiguation). Biology deals with the study of the many varieties of living organisms. Clockwise from top left: Salmonella typhimurium, Phascolarctos cinereus, Athyrium filix-femina, Amanita muscaria, Agalychnis callidryas, and Brachypelma smithi Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy.[1] Biology is a vast subject containing many subdivisions, topics, and disciplines. Among the most important topics are five unifying principles that can be said to be the fundamental axioms of modern biology:[2] 1. Cells are the basic unit of life 2. New species and inherited traits are the product of evolution 3. Genes are the basic unit of heredity 4. An organism regulates its internal environment to maintain a stable and constant condition 5. Living organisms consume and transform energy. Subdisciplines of biology are recognized on the basis of the scale at which organisms are studied and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions of systems of biological molecules; cellular biology examines the basic building block of all life, the cell; physiology examines the physical and chemical functions of the tissues, organs, and organ systems of an organism; and ecology...

...CHEMISTRY CHEMISTRY (CLASSES XI–XII) Rationale Higher Secondary Stage is the most crucial stage of school education because at this stage specialised discipline based, content oriented courses are introduced. Students reach this stage after 10 years of general education and opt for Chemistry with a purpose of mostly for pursuing their career in basic sciences or professional courses like medicines, engineering, technology and studying courses in applied areas of science and technology at tertiary level. Therefore, at this stage, there is a need to provide learners with sufficient conceptual background of Chemistry, which will make them competent to meet the challenges of academic and professional courses after the higher secondary stage. National Curriculum Framework for School Education – 2005 recommends a disciplinary approach with appropriate rigour and depth with the care that syllabus is not heavy and at the same time it is comparable to the international level. It emphasizes a coherent focus on important ideas within the discipline that are properly sequenced to optimize learning. It recommends that theoretical component of Higher Secondary Science should emphasize on problem solving methods and the awareness of Syllabus for Secondary and Higher Secondary Levels 22 historical development of key concepts of science be judiciously integrated into content. The present exercise of syllabus development in Chemistry at Higher Secondary Stage is based on this framework...

...Notes Enzymes: What must occur for a reaction to proceed? Collision Theory: 1. Reactants must collide 2. Reactants must have enough energy 3. Reactants must hit with proper orientation Here is morbid example of collision theory. How do a train and school bus react to give a train with engine damage and a school bus in two pieces? [pic] If you look back to the three conditions required for a reaction to occur, we can relate them to his terrible accident. In the collision theory, condition number one requires that the train must collide with the bus. Condition number two requires that the train and bus collide with enough energy for the reaction to occur, meaning the train must hit bus with enough energy, not merely tap the bus. The third condition requires that the train and bus hit with the proper orientation. If the bus hit the side of the train, it will not slice the train in have. The train must t-bone the bus. Hopefully this visual will help you to remember the condition required for a reaction to occur. Energy Diagrams: Energy diagrams are also called reaction progress diagrams as they depict the energy of the chemicals involved in the reaction through out the course of the reaction. The following is an example of an exothermic reaction: [pic] A catalyst will lower the activation energy of a reaction. The result is shown in the following reaction progress diagram for an exothermic reaction. [pic] The green line in the transition state is...

...The Rh factor (ie, Rhesus factor) is a red blood cell surface antigen that was named after the monkeys in which it was first discovered. Rh incompatibility, also known as Rh disease, is a condition that occurs when a woman with Rh-negative blood type is exposed to Rh-positive blood cells, leading to the development of Rh antibodies. Rh incompatibility can occur by 2 main mechanisms. The most common type occurs when an Rh-negative pregnant mother is exposed to Rh-positive fetal red blood cells secondary to fetomaternal hemorrhage during the course of pregnancy from spontaneous or induced abortion, trauma,[1] invasive obstetric procedures, or normal delivery. Rh incompatibility can also occur when an Rh-negative female receives an Rh-positive blood transfusion. In part, this is the reason that blood banks prefer using blood type "O negative" or "type O, Rh negative," as the universal donor type in emergency situations when there is no time to type and crossmatch blood. The most common cause of Rh incompatibility is exposure from an Rh-negative mother by Rh-positive fetal blood during pregnancy or delivery. As a consequence, blood from the fetal circulation may leak into the maternal circulation, and, after a significant exposure, sensitization occurs leading to maternal antibody production against the foreign Rh antigen. Once produced, maternal Rh immunoglobulin G (IgG) antibodies may cross freely from the placenta to the fetal circulation, where they form antigen-antibody complexes...
