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

Introduction In this lab we had to design a system that would test if changing the mass‚ angle of release and length would have any effect on the period of a pendulum. Hypothesis As the length‚ mass and angle of release change‚ the period (T) will change for each one of these factors. Materials Lab stand Protractor Cardboard Fishing line Stopwatch Weights Hook for weights Tape Ruler Weighing scale Logger Pro Variables Independent Angle of release Dependent Period Length

synthesize trans-9-(2-phenylethenyl) anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde through the reaction mechanism recognized as the Wittig Reaction. The Wittig Reaction allows the chemist to synthesize phosphoranes in the lab with relative ease. A more recent and inexpensive version of the reaction is the Wittig-Horner reaction (1). ABSTRACT Georg Wittig was a German chemist and Nobel Prize winner in 1979 for the Wittig reaction (1). He was born in Berlin‚ on June 16‚

Biosphere Lab Report A biosphere can be defined a lot of different ways. Our interpretation of a biosphere is the area in which life can be contained within. In the case of the earth‚ it means as high as a bird can fly and as deep as fish can swim in the ocean. A biosphere is a closed system that has a constant flow of energy between the organisms living within it and it needs nothing outside of itself but sunlight to continue to be sustained. At the University of Arizona‚ they attempted to build

LAB REPORT HYPOTHESIS 1: Plants transpire the most when the environment has light and less humidity JUSTIFICATION: Water evaporates more readily because light stimulates the opening of the stomata and photosynthesis would occur. HYPOTHESIS 2: Transpiration would occur the second most when there’s light and lots of humidity. JUSTIFICATION: The light would allow photosynthesis to occur and the stomata to open but little if any diffusion of water out the leaf would occur. HYPOTHESIS 3:

Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)

Organic vs. non organic There is a vast majority of food in our world today‚ when we consume this food we must stop to think about what exactly it is made of. In today’s society we are always looking for the best healthy foods that are available to us. We want good‚ nutritious‚ healthy foods so that we can live a long and healthy life. We live in a world where we have fast‚ cheap and processed foods all around us. Have you ever considered going a different route? Organic is a different way to eat

Chemical Report The chemical I will be writing this report on is oxygen. The name oxygen comes from the Greek word “oxygens‚” which means “acid producer”. Dictionary.com defines oxygen as “a colorless‚ odorless‚ gaseous element constituting about one-fifth of the volume of the atmosphere and present in a combined state in nature.” Oxygen has many uses today. First‚ oxygen is used by people‚ plants‚ and animals in the respiration process. Tanks of oxygen are used in the healthcare field to treat

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
