Gas Chromatography

In the control, beta-amylase was present unlike the experiment, which resulted in less molecules lingering. Discussion: 1. a. My results matched my prediction regarding alcohol percentage by weight. I predicted that the control would have a higher alcohol content than the experimental since beta and alpha amylase are working together. Since only Alpha-Amylase worked in the experimental, there was probably bigger carbohydrates present in the flask, therefore, there was a lower alcohol percentage since yeast can’t digest bigger sugars.

Other indeterminate random error consists in the apparatus and measuring accuracy, fluctuating at half the measurement of the lowest measurements made. This was especially important in the measurement of liquids, with +/- 0.05 millilitre differences in either the Hydrogen or the distilled water. Since these two liquids get added together, the error values add to create an overall uncertainty sum. This therefore provides the ASS and solution combined an error uncertainty of +/- 0.1mL. Due to the nature of this experiment however, this error is neglect able and the general trends form with high

Bio-diesel production yields undesirable by-products for example methanol and glycerin. These by-products are removed so that the bio-diesel is suitable for use. Fractional distillation is used in the essential oil, flavor and fragrance industry. Raw essential oils are extracted from different plants such as mint, clove and tee tree for example. These raw oils contains impurities that have a bad flavour or odor.

2. Eric’s unpredictable shock responses could be due to his low levels of adrenocorticotropic hormone (ACTH). Low levels of this hormone can cause him to act abnormally to stressors. The low levels of ACTH are due to the prevention of corticotrophin releasing hormone (CRH) from rising levels of cortisol that are being secreted into the blood (Marieb & Hoehn, 2013, p.614). 3.

If the beaker was not washed, not all the solution/precipitate would end up in the crucible/filtration system, which would mean a possible low reading on the mass and concentration of Al3+ because some of the precipitate would remain on the beaker. The precipitate left on the beaker would not be accounted for in the calculations, and would result in a lower measured mass and

What is Diabetes Insipidus and what causes it? Diabetes Insipidus is your ability to control the water balance within the body is not functioning properly. The kidneys are not able to regulate the amount of water passing in urine as well as normal. This means that you can pass large amounts of dilute urine. The medical term for passing large amounts of urine is polyuria.

Indeed, a volatile substance is considered as prone to vaporizing and separating. This could definitely be bad once the fuel vapor has its easy way out of the tank, therefore, allowing it to evaporate away into the air. Gasoline could degrade over time and could also lead to a number of problems. HOW LONG DOES GAS LAST? The amount of time that it takes for a gas to expire would depend on the age of the gas, the climate, and the formula together with some other factors.

Methanol is a light, colourless and flammable liquid that isn’t fit for human consumption due to its highly toxicnature. INDUSTRIAL SYNTHESIS Methanol is also known as wood alcohol because it used to be produced as a by-product of the distillation of wood. However, for modern-day methanol production synthesis gas is used. The synthesis gas must have carbon monoxide and hydrogen gas as its main components. The formation of

The chromatogram confirmed the identity of the lower boiling point solvent as acetone, and the higher boiling point solvent as toluene. The unknowns were correctly identified due to the clear presence of two plateaus in the experimental data. The hot plate was not turned on too high or too low to not obtain one of the three samples, and a sufficient number of values were taken in each part of the distillation before the mixture evaporated away to obtain approximately accurate data for boiling points. The ratio calculated for the volume of solvents in the mixture was .506/.488, where the composition of the mixture was 50.6% acetone, and 48.8% toluene. These two values did not add up to 100% because the GC also recorded some impurities,

Vitamins and Minerals: Peanuts have high vitamins and minerals level. Various studies show that the despite that peanuts have high in calorie and fats, they are considered as a healthy food. Benefits of Peanuts: 1. Reduce the risk of Heart: Peanuts are helpful in reducing the risk of heart because of its high level of monounsaturated and polyunsaturated fats. They reduce the artery diseases and strokes by increase healthy blood lipid profile.
