Introduction: This report required the successful identification of two unknown substances through experimental testing on a selective collection of materials and equipment. For the first substance (which will be either tin or aluminium)‚ two tests shall be done to ensure a decisive and educated decision onto what the substance is. The first step utilizes the dramatic difference in density between the two substances by measuring the volume and mass of the unknown substance. By calculating the volume (through

an Unknown Compound Purpose: The purpose of this experiment was to separate a mixture of two or more unknown compounds and identify them based on their melting point and reactivity with an acid or a base. Compound studied/Reactions: The organic solvent used in this experiment was methyl t-butyl ether (MTBE‚ 2-methoxy-2-methylpropane). The unknown that dissolved in the MTBE‚ but was insoluble in water. MBTE is very volatile and flammable. It was determined in the experiment that the unknown was

CHAPTER 1 Introduction A computerized identification system is used to verify the identity of a person. The data is stored in a database of a server. An identification card is a card giving identifying data about a person‚ as full name‚ address‚ age‚ and color of hair and eyes‚ and often containing a photograph: for use as identification at a place of employment‚ school‚ club‚ etc. There are various types of identification systems available and implemented across the globe. These are Biometric

Experiment 2 – Identification of Inorganic Solids Jesse Galina CHM 101 Lab Monday October 1‚ 2012 Unknown Solid – 2 Identifying my cation was rather easy because of the color of the powder when it was first given to me. It was pinkish/slight red when solid and when it was grounded up even further. This observation ruled out every cation except for some hydrated Co (II) salts. After being dissolved in water‚ the solution turned pink which agrees with the statement that the cation was Co

Systematic Identification of Bacillus subtilis and Serratia marcescens Through a Battery of Tests and Plates Introduction: The purpose of this experiment was to use a systematic battery of tube tests and plates designed to lead to identification of two unknown bacterial species‚ from the combination of all results. A sample of bacteria was used‚ labeled “Sample 4”‚ from which both species was to be obtained‚ one gram positive and one gram negative. Table 1 is a list of the possible bacteria to be

The tests detect the presence of disease causing pathogens of E. coli that produce Shiga toxins. E. coli bacteria commonly occur in nature and they are a necessary component of the digestive process in humans and most other mammals. Most strains of E. coli are harmless‚ but pathogenic E. coli can be responsible for inflammation of the stomach and intestines
