Everything you need to know about hydrocarbons INTRODUCTION: organic chemistry Organic chemistry is the chemistry of compounds that contain carbon and hydrogen. The element carbon has a special role in chemistry because it bonds with other carbon atoms to give a vast array of molecules. The varity of molecules is so great that we find organic compounds in many common products we use‚ such as gasoline‚ medicines‚ shampoos‚ plastic bottles‚ and perfumes. The food we eat is composed of different

Baking Project There are several chemical reactions taking place in the general baking of cakes. Every ingredient has its own function and causes a different reaction Synthesis: * Egg yolks (modify molecule’s structure) helps the oil-based and water-based components of the cake mix together. When eggs are cooked‚ the protein molecules become uncurled when exposed to heat and create new molecular bonds with other nearby protein molecules. When the egg is completely cooked‚ it helps form a

ETT4 Task 602.1.1-05 The lesson on pan balance equations has a clear purpose. The teacher is aware of the state standard that all 8th graders are to take algebra. By introducing some pre-algebra skills to students now will allow them to build on this prior knowledge when they reach 8th grade. Mrs. Soglin clearly states the objective of today’s lesson at the beginning of class. She tells the class that today they are going to learn about equations and pan balance. She is also providing a visual

Absorbance of Light vs. Concentration of Colored Solution Introduction: Performing this lab showed the importance of light in virtual drug screening because light can be used in a variety of ways to obtain different kinds of information in research. Light can be used to determine the concentration of DNA or protein in solution‚ tag different objects such as cells‚ protein structures‚ or bacteria in order to determine whether there is a large amount of a certain substance‚ and to determine the size
