Chemistry of Enamel Stephanie Gabrielle Estrada Texas A&M University- Corpus Christi Chemistry of Enamel Dentistry is a branch of medicine‚ in order to understand medicine including diseases related to the mouth‚ one must have a background knowledge over the chemistry of the enamel and how it interacts and takes place with compounds that are used in crowns‚ veneers and fillings. Enamel consists of approximately 96% inorganic minerals and 4% organic material. These inorganic components

disorder from occurring in these areas. One of the tactics being used is offender-focused hot spot policing. This type of tactic focuses on small places or groups of people in small places‚ and tailor specific solutions to problems using careful analysis of local conditions. This tactic has been used as an effective way to reduce violent crimes (cite). This paper will describe the goals of offender focused hot spots policing and provide evidence that this form of policing is effective. With every

Chemistry and Society Chemistry 110 March 17‚ 2012 Introduction Chemistry is very important in our lives even though we may not realize that chemistry is everywhere. This paper serves to examine the ways in which chemistry is relevant in everyday life and in society. It will also examine the difference between accuracy and precision and provide examples of when accuracy and precision are crucial in measurements and why society depends on these measurements to be accurate and precise ( Tam

If We Had Known About Green Chemistry In 1951‚ How Would Things Be Different Today? Green Chemistry is the making of chemical products that reduces or eliminates the use and production of hazardous substances in the designing‚ making‚ and use of chemical products. It involves the designing and re-designing of chemical creation and chemical products to prevent pollution which will therefore solve environmental problems. Green Chemistry is environmentally safe and has very little side effects on

Organic chemistry Organic chemistry is one of the ‘branches’ of chemistry and is seen as distinct from other branches‚ such as inorganic and physical chemistry. It can be described as the chemistry living processes (often referred to as biochemistry) but extends beyond that. It focuses almost entirely on the chemistry of covalently bonded carbon molecules and as well as life processes‚ it includes the chemistry of other types of compounds‚ including plastics‚ petrochemicals‚ drugs and paint

Chemistry 12 Unit 2 Notes - Equilibrium Chemistry 12 Tutorial 5 – The Equilibrium Constant (Keq) What is Keq ? The "K" in Keq stands for "Constant". The "eq" means that the reaction is at equilibrium. Very roughly‚ Keq tells you the ratio of Products/Reactants for a given reaction at equilibrium at a certain temperature. [Products] [Reactants] K eq = It’s not quite this simple when we deal with real substances. Let’s take an example. It has been found for the reaction: 2HI(g )

Descriptive Paragraphs The Hot Fudge Sundae In front of me on the table sat a beautiful pure white bowl‚ simplistic in design‚ hiding a decadent surprise inside. In the bowl was hidden something that was not so pure‚ however‚ the irresistible indulgence was worth every calorie that I knew it contained. As I looked inside I saw on the bottom of the bowl a hot‚ tender brownie loaded with macadamia nuts. I knew from past experience that the nuts had a creamy and smooth texture‚ almost like white chocolate
