Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze

Chemical Reactions Lab Synthesis Reactions: Synthesis reactions occur when two elements or compounds combine to create one single compound. The general equation of synthesis reactions is: A+B→AB. The following are the complete balanced equations for the five synthesis reactions performed in the lab. Reaction 1: Reaction 2: Reaction 3: Reaction 4: Reaction 5: The reaction of CO2 and water is a prime example of a synthesis reaction. This is a synthesis reaction because it follows the general

Lab‚ Week # 1 BALANCE LAB Introduction The purpose of this lab is to learn how to utilize two different balances to find the mass of different chemicals in the ChemLab program. A balance is an instrument used to determine the mass of a chemical. To accomplish this we use direct weighing and weighing by difference on both the centigram and electronic balances. Equipment 1 Centigram Balances 1 Electronic Balance 1 100ml Beakers 5 Copper Slugs 2 Unknown Weights (Label # 1‚ # 2)

Discussion The possible identity of the unknown organisms in the mixed culture was limited to bacteria that we had worked with previously in lab. Initially a Gram stain was conducted in order to distinguish the unknown bacterium as a Gram-positive and/or a Gram-negative organism (Lancaster and Bennett‚ 2012; Kellenberger‚ 2001). Based upon the results‚ both Gram-negative and Gram-positive bacteria were observed in the unknown mixed culture (Table 1 and Table 2; Kellenberger‚ 2001). In order

FIMolly O’Donovan Period 1 Anatomy October 25‚ 2012 Make up finger print lab Fingerprints are impressions created by ridges of the skin. The ridges are in the tips of the fingers‚ palms of the hands‚ and the sole of the feet. These ridges form before a baby is born. They do not change‚ but they can become larger. There are three different types of ridges in our population‚ loops‚ whorls‚ and arches. Crime investigators can save fingerprints by brushing powered in place with either camelhair

1/23/12 Silver Trade DBQ The global trade of silver had a devastating affect on the Chinese economy because China did not have the supply of silver that was needed to support their economy so they became dependent on the trade that the Europeans brought (1‚3‚7‚8). In Europeans states like Spain and Portugal we see their economies benefiting from the increase of the global silver trade because they controlled silver mines in the Americas and India (2‚4‚6). In china the increase of silver trade brought

Silver can be consider as one of the most all-around metals reachable. Indeed silver is a white‚ shiny and soft metal which is often found in its natural form as a mixture with other minerals and metals. Thanks to its properties‚ silver can be consider as a multi-function produce because it can be used in the industrial sector and also as an asset. Indeed‚ silver has a monetary value when paper money is no longer of value. For example‚ in period of inflation or deflation‚ the value of silver can

Document Based Question (DBQ): Global Flow of Silver During the mid-seventeenth century and early eighteenth century‚ many events occurred along with the global flow of silver bullion. In the early 1600’s‚ the Dutch East India Company was founded and this contributed to the Dutch Golden Age of trade‚ science‚ military and art. Also in the early 1600’s‚ Tokugawa Ieyasu seized Japan and made the Tokugawa Shogunate military government that was headed by the shoguns. In the mid 1600’s the Taj Mahal

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle
