Separation of a Mixture: Unknown # 12-Green Chemistry 221 with Professor Thomas Quale May 2012 Formal Lab Report Abstract An unknown sample‚ # 12-Green‚ was separated into its individual variable components‚ iron‚ ammonium chloride‚ silicon dioxide‚ and sodium chloride. The techniques used to separate the components of unknown # 12-Green‚ magnetism‚ sublimation‚ extraction‚ and filtration‚ were chosen based on the unique properties of each component. Using these separation techniques‚ each substance

this statement in 500 words and make relation to the text ‘Der Vampir’ by Heinrich Ossenfelder. Corruption is not the basis of all we fear. It is the unknown means through which corruption occurs that leads to our fear of its connotations. The unknown bringer of our degradation is the monster at the root of its causality—and thus‚ the unknown cause of corruption is the basis of all we fear. Der Vampir uses the girl’s ignorance to his true intentions to indicate that we do not fear the possibility

experiment‚ we are trying to find the identitiy of the unknown component of Panacetin. This is answering question 2 of the two questions that were to be answered in experiment 2. The equation of this reaction is as follows (and is the same as that found in experiment 2):  During this experiment‚ we used recrystallization methods in order to help in the purification of the unknown solid‚ as well as drying and vacuum filtration. We then ground the unknown and combined it with different chemicals (such

opportunity to practice proper heating and cooling techniques and to calculate the formula of a known anhydrous compound and to calculate the percent of water in an unknown hydrate from results. Materials and Methods: Materials used for this experiment included 3 crucibles (with lids)‚ clay triangle‚ ring‚ burner‚ CaSO4.2H2O and one unknown hydrate. In Part A‚ we assembled a Bunsen burner and heated 2 crucibles (and lids) for 5 minutes and then allowed them to cool to room temperature. Once cooled

After observing each slide under the microscope it was determined that unknown solution A was hypertonic because the RBC appeared to have shrunk. The RBC in unknown solution B appeared to be swollen‚ therefor‚ the tonicity of unknown solution B was hypotonic. Unknown solution C showed no change to the

The sinking of this liner involves a sequence of events that led to its sinking‚ main participants and groups that were involved and affected by the sinking‚ and it created a great significance and importance after it was over. The sinking of the Lusitania occurred because of a series of events that led to its plummeting. The Lusitania was a British vessel that at that time was on a voyage across the Atlantic Ocean from New York to Liverpool (Unknown‚ OL). There were

the students experimented to calculate the mass of unknown acid and its equivalence point using a method called titration and titration curve. The known volume of an acid solution would be titrated by slowly adding drops of solution into NaOH‚ and the volume of base needed to react with the acid is measured throughout. By using those data‚ the students are able to find what they were trying to calculate. On this lab‚ the students found the unknown acid‚ 4.36 x 10-5‚ and the equivalence point of 8

2017 Chemistry 1021 Section: 427 Benton Smith Discussion of Results The goals of this experiment were to find the identities of four unknown compounds and to first determine the pH. We then were required to run a series of anion and cation tests to determine the composition of the unknown solutions. To get more knowledge about these solutions we ran a series of dilutions to see if anything changed. Finally we tested the pH of household items and ran titration

centigram balance‚ the mass in grams and slugs to determine both weighing and weighing by difference. Also using an electronic balance the weigh of a slug will determine by using direct weighing and weighing by difference as well. Plus the mass of two unknown weights will be determined using a electronic balance with the same weighing techniques. When using the copper slug the mass was determine accurately by both direct weighing and by weighing by difference. But when using the electronic balance
