Chem Final Exam Combination Combination reactions‚ also known as synthesis reactions‚ involve the combination of two or more substances into a single new substance: A + B ---> AB Many metal oxides‚ for example‚ absorb carbon dioxide (CO2) from the air to form carbonates: CaO(s) + CO2(g) ---> CaCO3(s) Decomposition Decomposition reactions represent the reverse of the combination process in that one substance breaks down into two or more substances: AB ---> A + B Water‚ or H2O‚ for example

solution: Dissolve 10 mg of alkaline phosphatase enzyme in 10 ml carbonate -bicarbonate buffer to get 1 mg/ml stock solution. Pipette out 0.1 ml of stock A and make-up the volume to 10 ml with buffer to obtain 0.01-mg/ml solution‚ which is used for further dilution. Theory Chemical reactions in biological systems occur in the presence of highly specific protein catalysts called enzymes. Enzymes catalyse the reaction rapidly under mild conditions in contrast to inorganic catalysts. The rate of enzyme-catalyzed

Methods: (Refer to UDEE2124 lab manual from page 7 to page 10) Results: (I) Spectrophotometric Determination of DNA A260 = 3.923 A280 = 3.923 Conversion factor = 50 Dilution factor = 50 Therefore‚ dsDNA concentration (µg/ml) = A260 x conversion factor x dilution factor = 3.923 x 50 x 50 = 9807.5 µg/ml A260 / A280 = 1 Extracted plasmid DNA A260 / A280 < 1.8‚ therefore the extracted plasmid DNA contains impurity. (II) Agarose

MEMORANDUM To Apex Investment Partners: According to my analysis of the Accessline’s proposed term sheet‚ I do not believe that Apex would serve its own interests‚ or those of its investing partners‚ by investing in Accessline according to the terms proposed. By investing at the proposed valuation‚ according to the proposed control and incentive structure‚ Apex would be shouldering a disproportionate share of the risk should Accessline fail to meet its performance targets‚ or require

Purpose The purpose of this experiment is to apply Beer’s Law by analyzing samples provided by Q laboratory to determine their absorbance and prepare a Beer’s law plot. Molarity of these samples was also calculated to determine concentration and percent error rate. Students also analyzed the concentration of blue dye #1 to determine the concentration of blue dye #1 in a commercial blue dye drink. Procedure Exercise #1 Step #1: Convert %T (Table 1) to absorbance and prepare a Beer’s law plot

Experiments 4A-C: Synthesis and Component Analysis of an Iron (III) Oxalate Complex My Name TA‚ Section B## Work Performed on 10/23‚ 10/30‚ & 11/4‚ 200# Report due Tuesday‚ November ##‚ 200# 1. Abstract This experiment initially involved the synthesis of an iron (III) oxalate complex with the general formula Kw[Fex(C2O4)y]·zH2O. The variables x‚ y‚ and z were determined through the duration of the entire experiment. From 1.2000g of Fe(NH4)2(SO4)2 were synthesized 1.1###g of K3[FeIII(C2O4)3]·3H2O

PSBPP103 Differential Gram’s staining EXPERIMENT NO. 1 AIM: THEORY: Page No: C1 Date: To Gram stain the given bacterial suspension and to differentiate between gram positive and gram negative organism. Visualization of microorganisms in the living state is very difficult‚ not just because they are minute‚ but because they are transparent and almost colorless when suspended in an aqueous medium. To study their properties and divide microorganisms into specific groups for diagnostic purposes
