The lab in which we conducted last Tuesday was an analysis of a hydrate and what happens to it when it is heated. A hydrate is a crystalline compound which water molecules are chemically bound to it. In the lab‚ we were to analyze the difference in grams of the hydrate and the anhydrate. An anhydrate is the crystalline compound without the water molecules bound to it. During our lab‚ we were to heat up the crucible‚ the crucible with hydrate‚ and the crucible with an anhydrous and write down each

Unknown Report Alexis Grettenberger 800503431 Katie Young Alexis Grettenberger Biol 311 Lab 11/21/14 Preliminary Unknown Report Purpose: The purpose of this experiment was to identify a specific unknown bacterium that was isolated from a multitude of bacteria in a sample of contaminated dirt by running it through a series of identification techniques. Some of these techniques were simple staining‚ gram staining‚ and isolation techniques. The hypothesis of this experiment was that the bacterium

Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

Ahmad Shrab . Introduction This lab is purposed to familiarize basic equipment and techniques used in the study of microorganisms. In addition‚ learn some basic techniques used in identifying prokaryotes and make and view microscope slides of some common prokaryotes. In this lab ‚ I worked two experiments ‚ the first one is cultivation bacteria "colony "‚ and When microorganisms are cultivated

Purpose=The purpose of this lab was to combine reactants‚ which we would pick ourself‚ to make 2 grams of Copper Phosphate and another product. Background: Chemistry is the branch of science that deals with the identification of the substances of which matter is composed. Chemistry has to do with many things we use today. For example‚ fireworks are made by the chemical combining magnesium‚ titanium‚ copper‚ aluminum‚ strontium‚ or other periodical elements. Things also like making plastic‚ jewelry

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

While utilizing the methods stated above‚ the bacterium found was a facultative anaerobe due to the Gram Negative Rods‚ fermentation‚ and the production of indole. The specific Gram Negative Enteric Bacilli was Shigella dysenteriae. There are many reasons for knowing how to control bacterial growth as well as such as antimicrobial drugs‚ which assist the body’s defenses against pathogens.

Mariana Mendoza Alvaro Puccini Maria Quin Solubility Lab Purpose: The main purpose of doing this lab is to learn how to interpret solubility graphs and how the temperature does affects the solubility of different substances. There are other objectives of the lab which are learning what are concentrated‚ diluted‚ supersaturated‚ and saturated substances and how can they be identified. The hypothesis of this lab would be that when temperature increases‚ the amount of salt and copper
