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

Prehistoric Times - Beginning of the Christian Era (Black Magic) * 1700 BC King Hammurabi’s reign over Babylon In ancient Babylon King Hammmurabbi began to classify metals such as gold ‚ iron‚ and copper. He also gave certain materials higher value than others‚ depending on the potential of the material. Known metals were recorded and listed in conjunction with heavenly bodies. 430 BC Democritus of ancient Greece Democritus and the atom: c.420 BC In the late 5th century BC Democritus

Chemistry of cosmetics Few people would whip out a chemistry set‚ uncork the vials‚ and slap the compounds on their face. Yet‚ millions of women and girls essentially do that every day when they unzip their makeup bags and apply lipstick‚ mascara‚ and other makeup. Like the compounds in a chemistry set‚ makeup consists of chemicals. Although the chemicals in cosmetic products are intended to improve the appearance of skin‚ lips‚ and lashes‚ some can cause adverse effects. Emulsions The majority

The Inorganic Chemistry of Carbon Inorganic Carbon For more than 200 years‚ chemists have divided compounds into two categories. Those that were isolated from plants or animals were called organic‚ while those extracted from ores and minerals were inorganic. Organic chemistry is often defined as the chemistry of carbon. But this definition would include calcium carbonate (CaCO3) and graphite‚ which more closely resemble inorganic compounds. We will therefore define organic chemistry as the study
