2014 ! ! Physical and Chemical Properties! Purpose/Hypothesis:! • The purpose of this experiment is to investigate the chemical and physical properties of pure chemical substances. A property of a substance is some distinguishing characteristic. Some of the most common physical properties are color‚ odor‚ hardness‚ density‚ melting point‚ boiling point‚ and solubility in various solvents. For all of these properties‚ no chemical change takes place. Chemical properties describe the tendencies of a

Physical Properties The purpose of this lab was to see how certain substances; Naphthalene‚ Toulene‚ and and 2 unknowns (one liquid‚ one solid) react with 3 different solvents. To identify the two unknowns‚ testing needs to be done to find the density of both the liquid and the solid‚ determine the melting point of the solid‚ and the boiling point of the liquid. The Physical Properties of Pure Substances Table can then be used to compare the observed results with the accurate properties from the

Title: Colligative Properties & Osmotic Pressure Background: Important terms to study from this lab assignment are colligative properties‚ membrane permeability and osmotic pressure. First‚ colligative properties are “those of a solution that depend solely on the number of solute particles present‚ not the identity of those solute particles. These properties include: vapor pressure lowering‚ boiling point elevation‚ freezing point depression‚ and osmotic pressure” (p. 17 lab manual). In this experiment

3.7. Dielectric Studies Dielectric properties are the complex function of bulk permittivity‚ conductivity‚ size‚ shape‚ frequency and spatial arrangement of the constituents [27]. The Dielectric complex permittivity is written as where‚ the real part εr and imaginary part ε″ are known as dielectric constant and dielectric loss accounts for the energy storage and energy loss respectively. The dielectric constant is calculated with the relation εr=Cd/εoA where‚ C is series capacitance

Characteristics and Properties of Amino Acids Introduction: Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups. The R group is often referred to as the amino acid side chain. Amino acids have special common names‚ however‚ a three letter abbreviation for the name is used most of the time. A second abbreviation ‚ single letter‚ is used in long protein structures.Consult

Introduction: Frederick Engels wrote The Origin of the Family‚ Private Property and the State with the purpose of providing a materialist analysis of how the family as we know it came to be with the rise of class society--and with it‚ the oppression of women. While Origin of the Family was written after Karl Marx ’s death in 1883‚ it was largely based on notes that Engels and Marx made on the research of anthropologist Lewis Henry Morgan‚ who had published Ancient Society in 1877‚ making him one
