* Introduction to Organic Chemistry Understand the basis of drawing organic structures Depicting 3-D structures in 2-D Most organic compounds have a three-dimensional structure. How do we represent structures on our two-dimensional page? For example‚ methane is a tetrahedral molecule: Bonds in the plane of the paper: Bonds coming towards the observer: (out of the page) Bonds going away

to a garden (let alone the beach) their streets are full of cars; school playgrounds are usually flat‚ sterile areas of concrete which offer no interest or little opportunity for interaction.” The consequences of this according to his theory of Compound Flexibility is that children who have little control over the world inevitably have fewer positive experiences‚ which in turn slows the development of their self confidence. Loose-parts theory has also been referred to by Bob Hughes in his elucidation

Analysis: The graph of oxygen uptake vs time taken to run 1.5 miles has a negative linear association. As oxygen uptake increases‚ the time taken to run 1.5 miles decreases. This is can be seen through the gradient which has a value of 0.1705. This means that as the oxygen uptake increases by 1 ml/kg the amount of time taken to run 1.5 miles tends to decrease by approximately 1.7 minutes. The graph has a moderate relationship because the data is scattered in a wide band along the line of best fit

Organic Farming Organic farming is a form of agriculture that does not use synthetic‚ which means artificial‚ fertilizers‚ pesticides and genetically modified organisms. Organic basically defines a way of growing‚ processing‚ and handling food. Organic farming promotes biodiversity. The dictionary defines biodiversity as the diversity among and within plant and animal species in an environment. The goals of organic farming includes maintaining diverse crops‚ keeping soil healthy‚ reducing pollution

CHEMISTRY COURSE TITLE: General Organic Chemistry COURSE CODE: CHM 121 ‚ UNIT: 2.0 . INTRODUCTORY AND IMPORTANCE OF ORGANIC CHEMISTRY Organic chemistry is the study of the compounds of carbon. Carbon compounds are far more numerous than those of other elements because carbon are able to bond together to form a wide range of chains and rings. The subject is named organic chemistry because living organisms are composed of carbon compounds. Organic chemistry could be regarded as the

COMPOUND INTEREST Making or Spending Money SIMPLE INTEREST FORMULA If a principal of P dollars is borrowed for a period of t years at a per annum interest rate r‚ expressed as a decimal‚ then interest I charged is I Pr t This interest is not used very often. Interest is usually compounded which means interest is charged or given on the interest and the principal. Simple Interest Example COMPOUND INTEREST Payment Periods: Annually Once per year Semiannually Twice per year Quarterly

Ionic compounds are formed when a metal and a non-metal join together. When sodium metal is dropped into a gas jar of chlorine gas the elements react violently to form a new compound called sodium chloride joined by ionic bonds. To understand how this process works‚ we must grasp an understanding of what an ion is and what an ionic bond is. An ion is an atom that has an electric charge and is created when an atom (or a group) gain or loses electrons. (It has an electric charge due to the imbalance

Colton Kuhlers Chemistry Paper Organic vs. Non-Organic What should I eat‚ organic or non-organic? This has been is hot topic a lot now that the United States is trying to go healthy. For years people have been researching which is healthier‚ more economical‚ and the most available than the other. It is hard to know what to buy when one researcher says organics better and another researcher says non-organics better. Let me take this topic into more depth to explain myself. First‚ let’s me describe
