8.2.1 (iv) Fractional Distillation of Crude Oil By Blake Turner – Year 11 Fractional Distillation of Crude Oil Introduction Crude oil is the term for "unprocessed" oil‚ the stuff that comes out of the ground. It is also known as petroleum. Crude oil is a fossil fuel‚ meaning that it was made naturally from decaying plants and animals living in ancient seas millions of years ago -- most places you can find crude oil were once sea beds. Crude oils vary in colour‚ from clear to tar-black‚

PRINCIPLES OF CHEMISTRY LAB I Experiment 2 Separation Of Mixtures INTRODUCTION A mixture can simply be defined as a substance that is made up or consists of two or more elements and/or compounds that are physically combined but that have not reacted chemically to form new substances. A mixture may be a solid‚ liquid‚ gas‚ or some combination of those states. Mixtures can be found almost every wher in our everyday lifes and some common examples are * sand and water * salt and water

Introduction: Experiments 1 and 2 main aims are as follows: • To able to use the Beer-Lambert law to explain the relationship linking concentration and absorbance of the coloured solutions methyl orange and bromophenol blue. • To be able to rightly operate a spectrophotometer to assess the absorbance at various wavelengths • To be able to identify the main component parts of a spectrophotometer • To be able to draw a ‘Standard Curve’ from the data collected

Abstract Pyrorle-2-aldehyde and 1‚3-diaminopropane react under reflux to form a transition metal ion of Nickel(II)‚ that further more react with nickel acetate to form red crystals through condensation‚ the colour being constituded by the congugated bonds. These series of reactions synthesize the Schiff Base ligand and Nickel(II) complex of the Schiff base ligand. 0.36g of the Schiff base ligand is yielded and 0.1g of the nickel complex is yielded from the 0.36g Schiff base ligand and 0.5g nickel

Introduction Paracetamol is a medication used to relieve fever‚ its chemical name is acetaminophen. Its molecular formula is CH3CONHC6H4OH and its molecular weight is 151.2 g/mol. The melting point of pure compound is in the range of 169-172 ℃. During lab Paracetamol medication was dissolved in water‚ purified and recrystallized again. The purpose of the experiment was to learn basic recrystallization techniques that include hot and cold filtration. During experimental procedure sample was purified

Written report discussing the purity of my aspirin sample I produced. When I carried out the experiment to produce an aspirin sample I had to take a few results I had gained from carrying out the experiment later used these to work out the experimental error and percentage % yield. The results I used where the published value of what temperature pure aspirin melts at‚ the temperature my aspirin sample melted at‚ the weight of pure aspirin and the weight of impure aspirin. Firstly I worked out

Potato Osmosis and Diffusion Lab Report Emily Cocq Research Question: Will there be a difference in the experimented potato cores after being subjected to high concentrations of sugar? Introduction: Water can move through protein channels in cell membrane/cell walls. The water will move due to the water potential of the cells. If there is a greater concentration of solutes (chemicals) inside the cell than outside the cell and the chemicals can not move‚ then water will respond by moving

Aeroxide® TiO2 P90 (Evonik‚ Germany) was used in all experiments as the photocatalyst. The properties of TiO2 nanoparticles are given in Table 3.1 according to the supplier. The suspensions were prepared by dispersion of the desired amount of TiO2 in deionized water. The suspension was magnetically mixed at the stirrer speed of 500 – 600 rpm. Table 3.1.
