Introduction: The purpose of this lab was to separate and purify a compound. This was achieved using techniques that allowed the extraction of the acid‚ the isolation of the neutral compound and the melting point classification of the neutral compound to test the purity of the sample. Chemical Reactions: HA + OH- A- + H2O R-COOH + OH- R-COO- + H2O Organic Acid Insoluble in H2O Conjugate base Soluble in H2O Procedure: A 0.170g sample consisting of a mixture of 0.110g

Bags of Reactions * Problem/Purpose * Background Information: The Law of Conservation of Mass was created by Antoine Lavoisier in the 18th century. This law stated that mass could matter could neither be created nor destroyed. During a reaction the bonds of the reactants are broken and form new substances. As stated in the Law of Conservation‚ matter can neither be created nor destroyed; because of this the products should have the same number and type of atoms as seen in the reactants

We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia

Natalia Rey 080927440 BI338 Lab 1 Measuring the Success of Pisum sativum leaf cell fractionation: SDS-Polyacrylamide Gel Electrophoresis and Western Blot Analysis Introduction In order to evaluate the success of cellular fractionation‚ there are various methods that can be implemented that target specific proteins and/or receptors specific to particular organelles. SDS-PAGE (sodium dedocyl sulfate- polyachrylamide gel electrophoresis) is a technique used to separate proteins based on

DNA replication is a biological process that occurs in all living organisms and copies their DNA. DNA replication during mitosis is the basis for biological inheritance. The process of DNA replication starts when one double-stranded DNA molecule produces two identical copies of the molecule. Each strand of the original double-stranded DNA molecule serves as template for the production of the complementary strand‚ a process referred to as semiconservative replication. Cellular proofreading and error-checking

Introduction The purpose of this lab was to demonstrate the use of gene therapy on diseases that are caused by a single gene defect. This procedure was demonstrated on two different strains of baker’s yeast‚ EAY 235 and EAY 431‚ which both contained mutations in the LEU2 and TRP1 genes. Neither of these strains will grow without a proper medium that would supply both of these essential amino acids. The EAY 431 strain of yeast also contained a Rad 52 deletion‚ which caused EAY 431 to be a deficient

In the lab testing the heat of a reaction to understand changes in enthalpy in an exothermic reaction‚ the group hypothesized that if the amount of reactant is changed then the amount of heat produced (exothermic) will increase. This hypothesis was supported through the data as each of the six trials produced heat and the larger the piece of magnesium the larger the change in heat was. In the first trial the group had .085 grams of Mg and after being placed in 3 ml of 21.8℃ HCl the temperature of

The Sequence of Chemical Reactions Drew Selfridge Dave Allen‚ Lab partner Instructor Yang February 11‚ 1997 INTRODUCTION This experiment was to recover the most amount of copper after it is subjected to a sequence of reactions. The copper is originally in solid form‚ but the reactions will turn it into free Cu+2 ions floating in solution. The ions will then be regrouped to form solid copper once again. During this process‚ however‚ some of the Cu+2 ions may be lost. The copper will subjected
