1. Citric Acid * Citric acid is a weak organic acid with the molecular formula C6H8O7‚ which means a molecule of the acid contains six carbon atoms‚ eight hydrogen atoms‚ and seven oxygen atoms. When it is dissolved in water‚ it partially ionizes to yield three H+ ions (hydrogen atoms which are missing their electron) and a C6H5O7(3-) ion (the 3- means that it has three extra electrons.) The resulting solution is called an "electrolyte." Chemical Reaction When two dissimilar metals are put

The Role of the Citric Acid Cycle The Citric Acid Cycle is a series of enzyme-catalysed reactions that take place in the mitochondrial matrix of all aerobic organisms. It involves the oxidation of the acetyl group of acetyl CoA to two molecules of carbon dioxide. Each cycle produces one molecule of ATP by substrate-level phosphorylation‚ and reduces three molecules of NAD and one molecule of FAD for use in Oxidative Phosphorylation. The cycle is preceded by Glycolysis‚ which also occurs in anaerobic

Investigating the effects of acid rain in the growth of cress seedlings IntroductionAcid rain is rain or any other form of precipitation‚ which is unusually acidic. It has harmful effects on plants‚ animals and buildings. Acid rain is mostly caused by human emissions of sulphur and nitrogen compounds which react in the atmosphere to produce acids. Acid rain can slow the growth of vulnerable forests and cause leaves and needles to turn brown and fall off. In addition‚ it depletes minerals from the

orca held by SeaWorld‚ and the dangers of keeping the species in captivity. The killer whale‚ Tilikum‚ was involved in the deaths of three individuals. Gabriela Cowperthwaite started the film after the death of Tilikum’s trainer Dawn Brancheau‚ a 40-year-old senior trainer at SeaWorld. Cowperthwaite used many rhetorical devices in her documentary to make the audience feel bad for the orcas and what SeaWorld does to these wild animals. Gabriela Cowperthwaite’s documentary contained all three rhetorical

In 1927‚ a man by the name of Edwin Perkins created the very popular product know today as Kool-Aid. Kool-Aid was a popular drink mix right from the beginning which was sold in 6 different flavors to wholesale grocery‚ candy and other suitable markets (The History of Kool-Aid‚ 2012). In 1929‚ Perkins and his family packaged and shipped the Kool-Aid drink mix to grocery stores across the country using food brokers. The brand name became so popular that production moved to Chicago to become more efficient
