ups Identifying food groups in unknown solutions Aim The aim of this experiment is to identify different food groups within several different unknown solutions. This will be carried out by placing the unknown solutions into separate test tubes and using different chemical indicators to see if any reactions occur. Each food group will act different when the chemical indicator is added‚ some will change colour while others will separate. Introduction Food is a vital source of energy that is

Lab Eight: Identification of HydrocarbonsWebGoogle+GmailDocsmore ▼ All DocsEdit Orgo Chem Lab 8 Lab Eight: Identification of Hydrocarbons Organic Chemistry 311 Abstract: Unknown hydrocarbon K was identified by using purification‚ determination of boiling point by using the capillary tube technique‚ the calculation of density and obtained refractive index value from the Abbe-3L refractometer. The density was not useful due to an error of the machine but the boiling point and refractive index

As an eight-year-old pipsqueak who was regularly pitted against the twelve-year-old Goliaths of Albuquerque’s 12U tennis division‚ losing 0-6‚ 0-6 became a natural part of life‚ and I hated it. In fact‚ my tournament to-do list consisted of a dreadfully long car trip‚ suffering defeat upon defeat to another unnamed middle-school giant‚ and then drowning myself in a sea of tears while my dad lectured me about "unforced errors" on the trip home. As a result‚ I started to run away from tennis. I performed

I’m not as glamorous as I might seem. I’m just an ordinary student in 10th grade‚ who likes to learn things. Others may be more charismatic or handsome‚ but I have something that they do not. I posses an essential life skill; initiative. You (as the readers from the National Honors Society) may think that what I am saying is absurd‚ but I am here to prove my worth one paragraph at a time. I am a well educated individual who has repeatedly demonstrated initiative and high standards of reliability

Hydrolysis of macromolecules Abstract: This lab was designed to teach the process of “hydrolysis”‚ a chemical reaction in which water is added to a polymer‚ breaking its bonds and forming smaller molecules. A hydrogen cation and a hydroxide anion (which once formed water) break apart and attach themselves to the ends of shorter polymers. Hydrolysis plays an important role in our lives and in the lives of every living thing on earth. Living organisms rely on digestion (hydrolysis) to convert food energy

Experiment 3 : Identification of food constituents in milk Objectives To compare the composition of two different kinds of milk for fats‚ protein and reducing sugar. Introduction In this experiment two milk samples are given and its compositions are tested using different methods such as using benedict solution to test the presence of reducing sugar‚ using copper II sulphate to test the presence of protein‚ using K3( to test the presence of fat. However in this experiment‚ not only are

OBJECTIVE The main objective of this experiment is to carry out qualitative analysis to identify metal cations in unknown solution 1. INTRODUCTION An unknown material can be determined by using simple chemical tests and separations which is called as inorganic qualitative analysis. The separation of cations depends on the difference in their propensity to form precipitates. Separation scheme is used to classify cation into five groups on the basis of their physical and chemical behavior opposed

Title Testing Kool-Aid Mix for Food Dye Additives Purpose What food dye additives go into the food products we consume and how do these additives affect our perception of that food? Hypothesis If “Black Cherry” flavored Kool-Aid Mix appears red‚ then it will contain the food dye additive Red-40 that emits a red pigment. Background Food color not only affects the appearance of food‚ it also affects our perception of how food tastes. Tests have shown that consumers will choose colored drinks over

demonstrated that the color of a given food dye depended on which light was transmitted in the visible spectrum and which light was absorbed. A quantitative measurement of the absorbance spectrum of each food dye was obtained through spectrophotometry.1 Through this method‚ we determined that the wavelength of maximum absorbance of a given food dye was directly correlated to the color of that food dye. Further‚ darker food dyes absorbed more light than lighter food dyes (Table 1). The relationship between

I assessed a patient with hip problem who came to the physical therapy department in the medical complex. After the clinical examination‚ i suspect there may be a Hip Labral tear that requires further investigations and testing to confirm the clinical diagnosis. i gave the patient a written note for his physician that suggests further diagnostic testing which may help to set an accurate diagnosis of the hip problem. His doctor wrote a letter back stating that the patient should have been at first
