Report on the preparation and stability of liquid Paraffin Emulsion Abstract This study describes the preparation of a Liquid Paraffin Emulsion from Paraffin oil‚ Emulsifying agents and Distilled water. This report will also evaluate the stability of the Liquid Paraffin Emulsion depending on how the emulsion is produced and whether using different methods of mixing will produce a more stable Paraffin Emulsion. Introduction An emulsion is a mixture of two or more liquids that are normally not

individual concentrations or partial pressures directly may be not always be practical‚ however. If one of the components is colored‚ the extent to which it absorbs light of an appropriate wavelength may serve as an index of its concentration. Pressure measurements are ordinarily able to measure only the total pressure of a gaseous mixture‚ so if two or more gaseous products are present in the equilibrium mixture‚ the partial pressure of one may need to be inferred from that of the other‚ taking into account

Practical Report Experiment 1 Abstract In this experiment we found that you can calculate the density of elements with close presotion with crude experiments Introduction The aim of this experiment was to see how close you could measure the density of atoms with crude experiments. The second part of the experiment dealt with Solubility of large ions and their Hydration enthalpy. Hydration enthalpy is the enthalpy change when 1 mole of an ionic substance dissolves in a solution to give a solution

Thermodynamics- Enthalpy of Reaction and Hess’s Law December 5‚ 2011 Kylie Case‚ Emma McKee‚ Rebecca Smith Purpose: In this lab‚ the purpose was to verify Hess’s Law. Theory: Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The first being enthalpy of reaction‚ ΔHrxn‚ which is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great

CHEMISTRY LAB REPORTS How to Write a Lab Report Lab Reports gives the explanation of the experiment done Lab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report‚ use that. Here ’s a format for a lab report you can use if you aren ’t sure what to write or need an explanation of what to include in the different parts of the report. A lab report is how you explain what you did

collected for study can be grown and visualized in both liquid and solid growth media. The purpose of the media is to provide all of the necessary nutrients for microorganisms to live and reproduce. Although the reproduction of harmful bacteria may be hazardous‚ it is necessary for microbiologists to grow high populations of bacteria in the attempt to study the causes and provide prevention methods for spreading harmful bacterium. The purpose of this lab was to collect and observe microorganisms from the

Polypeptides‚ better known as proteins‚ carry out nearly all of a cell’s functions. A protein is made up of at least one or more amino acid polymers. The necessity of proteins for life is unequivocal‚ not only do they help to form the structures of cells but they act as enzymes in reactions of the body1. Enzymes are biological catalysts that lower the amount of activation energy needed in carrying out biochemical reactions1. Enzymes are responsible for almost every reaction that occurs in a cell

table represent the same thing‚ the temperature of the solution during fractional distillation. At the start of the fractional distillation‚ before we started the fire‚ it was 25° celcius. At the end of the fractional distillation‚ when all of the liquid was gone‚ it was 99.3 degrees. This set of data is not the first time we did the fractional distillation‚ it’s actually probably the 3rd or 4th. The first time we didn’t actually record the temperature‚ we just looked for the plateaus‚ we found them
