were liquid‚ oily‚ and it had a banana smell. Introduction Artificial flavoring is commonly used in the food that we eat today. For example‚ fruit flavoring is a chemical mixture that mimics a natural flavor as that of banana flavor from the synthesis of isoamyl acetate. Ester is the functional group‚ which is responsible for the distinctive odor and taste that artificial fruit flavoring has. Esters are derived from carboxylic acids. A carboxylic acid contains the –COOH group‚ and in an ester

The Chemistry of Love: Could the first opportunity to fall in love influence our ability to love for a lifetime? There are many different types of love: sexual‚ romantic‚ platonic‚ filial‚ maternal‚ paternal‚ spiritual‚ love of self‚ love of country‚ love of possessions to name a few. Love for our mother‚ our first love‚ could be the pivotal love around which we build our ability to love in every other way. This paper will look at the chemistry that is involved in the baby’s first opportunity

amount of each substance. Balancing a chemical equation refers to establishing the mathematical relationship between the quantity of reactants and products. The quantities are expressed as grams or moles. Balancing equations is a fundamental skill in Chemistry. Steps in balancing equation: 1. Write the unbalanced equation. Chemical formulas of reactants are listed on the lefthand side of the equation. Products are listed on the righthand side of the equation. Reactants and products are separated by putting

Soluble | Phosphate PO 3-4Carbonate CO 2-3Sulfite‚ SO 2-3 | H | Soluble | Once you recorded all of the data‚ there were a few questions that needed to be answered. A. Compare your results with the solubility rules and/or solubility table in your chemistry text. I would say that my results turned out pretty close to the rules in the text book. I observed many different reactions occurring. The colors of the solutions changed from clear to purple‚ from clear to blue and yellow‚ and from clear to a milky

Chemistry of Sunscreens “Over 400 years ago‚ Copernicus declared that the sun was the center of our universe. Primitive societies in every continent have worshiped the sun as the god that provided warmth and made the crops grow” Today‚ the sun is not something we worship but something we try to avoid due to the fact that we are aware that it contains two main sources of ultraviolet radiation that is harmful to our bodies. Ultraviolet radiation (UVR) is defined by wavelengths‚ and is divided

Elisa Hofmeister Kokesh Hour 3 AP Chemistry 5-29-12 The Chemistry of Coffee Green Coffee- Before coffee is roasted‚ it is referred to as “green coffee”. The green coffee is primarily made up of caffeine‚ lipids‚ carbohydrates‚ proteins (amino acids)‚ and organic acids (although inorganic acids exist in coffee as well). These groups are quite stable in the green phase‚ and it is the carbohydrates‚ proteins‚ and acids that will undergo significant reactions during roasting to produce coffee

CHEMISTRY PROJECT INVESTIGATORY PROJECT ON: CAFFINE CONTENT OF TEA About caffeine: Caffeine is a naturally-occurring stimulant‚ found in several plants. Caffeine is water soluble‚ and is extracted into the brewed cup when preparing tea‚ coffee‚ or other caffeinated drinks. The most well-known plants containing caffeine are the tea plant‚ Camellia sinensis‚ coffee‚ yerba maté‚ and guayusa. Although tea is known to have a number of health benefits‚ heavy caffeine use is known to have unpleasant
