Carlie Haeffner Qualitative Analysis March 20‚ 2015 The purpose of this lab is to identify unknown ions in a solution by using a type of chemical reaction called precipitate reactions. The key to finding which ions are present in a solution is to form a precipitate which makes the ions “come out” in a reaction (McNeil‚ 2013-2014). Water is used in these experiments to act as a solvent. Since water is a polar molecule‚ the slightly positive and negative charges will sometimes pull apart molecules

The initial theory of continental drift was put forward by a German meteorologist Alfred Wegener in 1915. This theory did not seem credible until it was connected with the plate tectonic theory in the mid 1960’s. The Tectonic plate theory had an advantage over previous predictions as it could be supported by observed occurrences. One such thing that supports these two theories is that seen from space the continents look as if they might once have been joined together. This possible idea was then

The San Andreas Fault and its role in Plate Tectonics and Earthquake Prediction The San Andreas Fault is one of the most widely studied faults in the world. Scientists use an array of methods in collecting data and providing analysis of fault characteristics both past and present. Presently there are many differing hypothesis and models used to describe crustal movements and deformation within the Pacific and North American plate boundary. Historical earthquakes along this fault have proven to be

A bacterium of choice by Frederick Griffith was S. pneumoniae cells also known as Pneumococcus bacteria. This is due to the growth of bacteria inside the body of a host regardless in the form of either solid or liquid cultures. In 1928‚ Frederick Griffith studied and published his findings on the different strains of Pneumococcus bacteria. There were 2 in particular that looked different; S and R. The R colonies has rough surface whereas the S colonies have smooth surface. Intrigued by the experiment

A. The typical human mouth contains a writhing orgy of bacteria. Most of these. Most of these microscopic organisms are bengin‚ and some are even beneficial‚ but one particular variety is a conspicuous troublemaker: Streptococcus mutans. These ubiquitous bacteria thrive on sugars in the mouth‚ which they consume while excreting lactic acid. This acid is responsible for the great majority of tooth decay in humankind because it erodes the enamel and dentin of the teeth. B. A Florida-based company
