Most likely‚ the part is one of the five following polymers: polyethylene‚ polypropylene‚ polystyrene‚ polycarbonate‚ poly(vinyl chloride). These are all extremely common‚ and have widespread applications in industry. Each of these polymers exhibits properties which allow it to be of unique technological importance. Theoretical values for the properties utilized in determining the identity of the unknown

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 Property development is a complex process that involve extensive planning‚ large amount of capital‚ complex activities and procedures‚ requires services from various parties and usually involves lengthy process. As a matter effect‚ it usually a high-risk investment that can influence changes in the economy and the property market itself. Poor planning on the development and parties involves will cause the project result in loss especially to the owner. However despite all the risk‚

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

has allowed me to gain knowledge and realise that there are still many issues and concerns being raised in our community‚ that determines whether our actions are acceptable or not by society. Through my analysis of the prescribed text‚ the play “A Property of the Clan” by Nick Enright‚ I have realised that there are still numerous concerns and problems in our younger society‚ with many of them the way we treat each other in a community.

Water has many unique properties that make life possible on Earth. One property is cohesion. The cohesion property is properly defined as the binding of water molecules by hydrogen bonds. Water has this property as a result of the chemical bonding between water. Cohesion of the strong hydrogen bonds allows the water molecules to stick together‚ almost as a unit of one. A force exerted on one of the molecules will be exerted on all of the adjacent molecules as a result of cohesion. Cohesion‚ often

Abstract: Dielectric properties of K2Pb(SO4)2 at different temperatures were studied with respect to frequency and the results were discussed. In our present work‚ K2Pb(SO4)2 was synthesized at 80°C using potassium sulphate and lead nitrate of high purity as the starting material. The structural property of the material was studied by X-ray diffraction (XRD). The functional groups present in the material were identified using Fourier Transform Infra-Red (FTIR) Spectroscopy. The thermal behaviour

How constitution protect against tyrany Tyrany can be compared to one of the most harsh’s thing’s to be brought up for law making. The constitutionwas written in the year 1787 over in philidelpia so it could respond to a call for the contitutional convention. The constitution protected the people from tyrany with three braches. Tyrany is a bad goverment that makes bad laws. The constitution protected in many ways fedralism‚seperation of powers‚checks and balances‚and small states versus
