Acetic Acid H 3
842 wordsIn the simple formalism proposed independently by Bronsted and Lowry in 1923, an acid was defined as a proton donor and a base was defined as a proton acceptor. In the simple acid-base reaction shown below, H 3 O+ is termed a Bronsted Acid, and HO- a Bronsted Base. In writing organic reaction mechanisms, the flow of electrons is often shown using "curved arrows" and in the example shown, the arrows are designed to show that an unshared pair of electrons from hydroxide anion moves to abstract a p...

Copper In Nitric Acid
554 words3 Cu + 8 HNO 3 -- 3 Cu (NO 3) 2 + 2 NO + 4 H 2 O The balanced equation seen on the top is what you attain when you place copper metal in concentrated nitric acid. In this process the identifiable characteristics of the metal will be completely changed and a new substance, cupric nitrate, will be formed. Copper forms two series of chemical compounds: cuprous, and cupric. Cuprous compounds are easily oxidized to cupric, in many cases by simple exposure to air; cupric compounds are stable. When nit...

England Journal Young Girls
660 wordsI discovered that mitochondria evolved from the chloroplast (Audersirk p. 369). The endosymbotic hypothesis championed most force full by Lynn Margulis of the University of Massachusetts, propose that cells acquired the precursors of mitochondria and chloroplast by engulfing certain types of bacteria. This happens by the aerobe bacteria that absorbs those molecules and used energy oxygen to complete their metabolism. By gaining a high range of energy, using large food resources, great amount of ...

Sulfur Dioxide Acid Rain
318 wordsAcid Rain is, rain that is acidic (naturally). There is a pH level scale which tells if something is acidic or not. Due to certain chemicals in the rain it has a pH level of around 5. 0, and sometimes even 4. 0 (around volcanoes activity). The term acid rain is now used for rain with a pH below 5. Acid rain is caused when gases, generally like sulfur dioxide (SO 2), dissolves into water to form sulfuric acid. The rest comes from different oxides of nitrogen (mainly NO 2 and NO 3). The chemical r...

Million Years Ago Long Period Of Time
1,219 wordsFrom Water to Land (Revision) Abstract: The early tetrapods were the first vertebrates to actually walk the solid earth. They began their conquest of land in the Paleozoic era around 360 million years ago. The question many paleontologists have been asking for a long period of time is whether the anatomy for locomotion on land was developed in water for swimming purposes, or if it was adapted after the creatures became terrestrial. Recent findings of fossils indicate that the transformations of ...
