physical & chemical behavior to benzene STRUCTURE OF BENZENE – - there are several characteristics of benzene which‚ although initially seemed contradictory‚ helped finally to determine its enigmatic structure a) Unsaturated Molecular Formula – - benzene ‘s molecular formula (MF = C6H6 )‚ indicates a high level of unsaturation - recall the calculation of centers of unsaturation (CU): CU = (2n + 2) - # H’s 2 [2(6) + 2] - 6 2 where n = #C’s For C6H6: CU = CU = 4 benzene is a highly unsat’d

Geometry Notes Second Semester I. Area‚ Surface Area and Volume & Circumference Circumference is the linear distance around the outside of a circular object. • C = π • d or π • 2r. • d = diamater or (radius • 2) • r = radius II. Perimeter Perimeter is the distance around a figure. * It is found by adding the lengths of all the sides. * Finding perimeter on the coordinate plane may require the use of the distance formula: (2 x width) + (2 x height) III. Regular Polygon • A regular

(Allen‚ 1997‚ para. 2). For the earliest period of Greek mathematics‚ there are few primary sources of information. We are therefore forced to rely extensively on the Euclidean Summary of Proclus. This contains an outline of the development of Greek geometry from early times until Euclid (Allen‚ 1997). Thales is often considered to be one of the first Greek mathematicians. The proposition known as the “Theorem of Thales” states‚ “The diameter of a circle always subtends a right angle to any point

mathematician‚ often referred to as the "Father of Geometry". He was active in Alexandria during the reign of Ptolemy I (323–283 BC). His Elements is one of the most influential works in the history of mathematics‚ serving as the main textbook for teaching mathematics (especially geometry) from the time of its publication until the late 19th or early 20th century.[1][2][3] In the Elements‚ Euclid deduced the principles of what is now called Euclidean geometry from a small set of axioms. Euclid also wrote

Biochemistry is a very interesting subject to study and eventually work in. From studying microorganisms to creating medicine to prevent alien viruses from infecting people‚ it has always been a fascinating subject to me. I became interested in this career because I was always interested in the science field. Ever since I was young‚ I always liked to experiment with different things. I found out about biochemistry by my chemistry tutor. In the first semester‚ I struggled with chemistry so I called

Mt. Eden High School Mr. Arzumanov: Conceptual Geometry Syllabus Class Website: http://new.schoolnotes.com/sarzu Welcome to Conceptual Geometry! This course will use the textbook Geometry: Concepts and Applications. Conceptual Geometry builds upon the concepts presented in Algebra 1. New content is introduced as an extension of material previously mastered in the abovementioned course. A primary goal of Conceptual Geometry is the use of mathematical ideas in solving problems ranging f

Fermat’s last theorem Currently holding the world record for longest standing math problem ever‚ Fermat’s last theorem went unsolved for 365 years. Fermat’s last theorem was one of the largest white whales in the study of math. Over the centuries‚ thousands were puzzled by the impossible problem. From its conception to its solution‚ Fermat’s last theorem was one of the most difficult to solve yet easy to understand problems in mathematics. First‚ I will discuss the theorem and how it was introduced

The Distance Formula In week one‚ we learned a simple yet extremely useful math concept‚ the Distance Formula. This formula uses the Pythagorean Theorem to determine the distance between two points on the rectangular coordinate system. Variations of the Pythagorean Theorem such as the Distance Formula can be used in building things or making plans to build something. Scenario Suppose you are volunteering at the local community center. The community center committee is planning to install
