and sea sand (SiO2) will be separated using the separation techniques in order to demonstrate the properties of mixtures and their ability to be separated by physical means. INTRODUCTION: This lab was based on the separation of the components of a mixture. A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically combined. All of these techniques involve changes in the physical state of a chemical

‘Aseptic Technique’. For procedures such as pressure sores‚ leg ulcers‚ simple grazes’ removing drains or sutures‚ the ‘clean technique’ is used which is a modified aseptic technique and aims to avoid introducing micro organisms to a susceptible site and also to prevent cross contamination to patients and staff‚ it differs from an aseptic technique‚ as the use of sterile equipment and the environment are not as crucial as would be required for asepsis (Gough 2009). The Aseptic technique is one of

chromatography (stationary phase is in form of a plane). Paper chromatography follows the basic principle of chromatography‚ which states that substances or components are distributed in between the stationary phase and the mobile phase. It is an analytical technique‚ where only a small amount of a sample is used for separating and identifying its components. Like any other method of chromatography‚ paper chromatography has two phases - the stationary phase and the mobile phase. In paper chromatography‚ porous

Separation of a Mixture: Unknown # 12-Green Chemistry 221 with Professor Thomas Quale May 2012 Formal Lab Report Abstract An unknown sample‚ # 12-Green‚ was separated into its individual variable components‚ iron‚ ammonium chloride‚ silicon dioxide‚ and sodium chloride. The techniques used to separate the components of unknown # 12-Green‚ magnetism‚ sublimation‚ extraction‚ and filtration‚ were chosen based on the unique properties of each component. Using these separation techniques‚ each substance

Percent Composition Report Hypothesis : By using seperation techniques properly‚ the 3 substance such as; water‚ sand‚ and salt can be seperated and the percent composition of each substance. Which will then be calculated theoritically and after comparison with the actual result‚ the accuracy of the 2 result can be found. Aim : The aim of this experiment is to compare the gravimetric result of the original mixture and the separated substance. The other objective is to calculate each percent

Appliqué Work What is Appliqué? Applique comes from the French work appliqué‚ which means to “put on”. Appliqué means to ‘place on’ fabric pieces that are sewn onto a larger piece of foundation fabric in order to create designs. In this art‚ colored pieces of cloth after being shaped into different images of birds‚ animals‚ flowers and many other forms are stitched on other cloths that are used on wall hangings‚ lamps‚ umbrellas and other household items. It is distinct from what is known as

Identity and Belonging Quotes An un-named song is like an un-named child; it has no identity. From the beginning‚ each human embryo has its own unique genetic identity. The firmest friendship is based on an identity of likes and dislikes. We all need a past - that’s where our sense of identity comes from. Follow your cultural and religious customs in your own home‚ but do not attempt to impose them on society. Rather than this‚ love each person as your own brother or sister‚ not seeing him

Various foraging relationships were determined through conduction of this experiment. Three different experiments were carried out in order to effectively meet the terms of the objective. A wooden foraging board was used to stimulate a foraging patch. This consisted of a rectangular wooden board‚ approximately 1’ x 1.5’‚ with approximately 75-80 shallow holes randomly drilled into one flat face. The randomly situated holes impeded the predator’s ability to forage in a systematic and planned manner
