Conclusion and Evaluation Conclusion In our test we put six different sliced up potatoes chips in solutions. The solution was different concentration of salt and water‚ one was 5% sugar‚ one 10%‚ one 15%‚ one 20% and one 30% salt concentration. We measured the mass of the potatoes chip before and after we put it into the solution. To keep the experiment fair we only changed one variable which was the salt concentration. The results that we got showed the chip went up in mass for 0%

have been taken in the experiment. There is five safety factors that should be taken while doing the experiment in laboratory: Make sure our hands are dry when switch on the switch of the machine Make sure the turbine is not stopped immediately as it tends to overspeed with emergency stops. Make sure the equipment function well before experiment get started. Must follow procedure going on the experiment so accident could be avoid during experiment. Make sure handling

Barry Allahyar Dr. Dodd CHEM 2122 2010-09-16 Experiment 19: Fischer Esterification‚ Conclusion The objective in this experiment was to efficiently perform an Fischer esterification of 1-butanol and acetic acid to form water and n-butyl acetate‚ and to confirm the esterification using IR spectroscopy analysis. It was found that 0.734 grams of n-butyl acetate was formed with a percent yield of 61%. The product was confirmed using IR spectroscopy and boiling point confirmation. The reaction mechanism

Austin Vandermey GS-1140 April 4th‚ 2015 Experiment We as a society have one big problem on our hands. This problem is sleep deprivation because there are not enough hours in the day to get stuff done. Between work‚ school‚ family‚ and leisure it seems like we do not have enough time to get are daily tasks done let alone have time for sleep. It is recommended by the U.S Department of Health that people need a solid eight hours of sleep to maintain good health. I don’t know about you

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

This section presents an example that shows how to develop a simple Bean and connect it to other components via the BDK. Our new component is called the Colors Bean. It appears as either a rectangle or ellipse that is filled with a color. A color is chosen at random when the Bean begins execution. A public method can be invoked to change it. Each time the mouse is clicked on the Bean‚ another random color is chosen. There is one boolean read/write property that determines the shape. The BDK

The Effects of Different Stress Levels on Bean Plants: Thigmotropism May 3‚ 2012 Abstract Bean plants were planted and rubbed a certain amount of times a day to apply stress. This was to see how plants might survive in a windy area or in an environment where they might be constantly touched or moved around. They were put under four different stress levels‚ and the plants were measured before the start of treatment to determine how they were being affected. The hypothesis was that those who

The winged bean (Psophocarpus tetragonolobus) is a twining‚ perennial herbaceous legume which can climb to 3-4 meters (Kantha and Erdman‚ 1985). As a leguminous plant‚ winged bean can be used in almost all parts of the plant. Fruit‚ leaves‚ flowers‚ bulbs and seed are edible and contain high protein and oil (Kotaru et al.‚ 1987; Dwiani et al.‚ 2014). The mature‚ dry seed is the most nutritious part of the winged bean. Their outstanding nutritive quality is based‚ above all‚ on their high protein

The hypothesis for this lab is if strawberry DNA is separated from other components‚ then when it is placed in a insoluble solution the DNA can eventually be isolated. DNA is deoxyribonucleic acid. Its a self replacing material present in all living organisms as the main constituent of chromosomes. It is the fundamental and distinctive characteristics of someone or something‚ especially when regarded as unchangeable. DNA extraction is the removal of deoxyribonucleic acid from the cells or viruses
