Introduction Identification and classification of bacteria is important to make easier manipulation on the bacteria for various purposes such as for medical‚ research‚ developmental‚ and biotechnicalfieldsThe cell wall is the basis for classification of bacteria according to the Gram stain. Accordingto the chemical make up of bacterial cell wall‚ a staining procedure‚ Gram stain‚ helps usclassify bacteria into two subgroups‚ The cell wall can stain either positive or negative‚depending on its chemistry

candy)‚ or hard (glass candy). You can make fudge by continuously stirring the sugar syrup after a period of cooling‚ so when the sugar crystals form‚ they stay very small and do not grow that to be big. You can make cotton candy or glass by cooling the syrup quickly to keep the crystals from forming. The main difference between the types are whether sugar crystals are allowed to form and if they do what their size is. The text is structured as an article and Tom Husband decided to bold the most

SCORE Paragraph 1 There are three phases whereby each has a different crystal structure at three different temperatures. At room temperature (298K)‚ Phase III is present whereby Cs3H(SeO4)2 has a crystal structure of a monoclinic with a space group of C2/m. At 400K‚ Phase II is present whereby Cs3H(SeO4)2 has a crystal structure of a monoclinic-A2/a symmetry. At 470K‚ Phase I is present whereby Cs3H(SeO4)2 has a crystal structure of a trigonal with a space group of R3-m. In Phase III‚ as we

*Recrystallization- solid compounds Recrystallization - precipitation of a solid cpd. from a saturated solution in the form of crystals through cooling or evaporation -7 steps: 1) selecting the appropriate solvent 2) dissolving the solute 3) decolorizing the solution 4) removing suspended solids 5) crystallizing the solute 6) collecting and washing the crystals 7) drying the product - 2 Kinds of Impurities: 1) more soluble 2) less soluble than the main component - impure

Recrystallization and Melting Point of Benzoic Acid Organic Chemistry 1 10/4/12 Abstract Recrystallization was done to remove impurities from the sample. The percent recovery of benzoic acid during recrystallization is 23.02%. The difference between the pure and impure samples was observed by comparison of melting points. It was found that impure sample had a lower and wider melting point range of 120.1-122.2 (C). The pure sample melting point range was 121.3-122.5 (C). These ranges helped determine
