The experiment is made of yeast and yeast is a single-celled fungi. The yeast contains an enzyme called catalase. A catalase works as a catalyst in this reaction. Catalase is a natural enzyme found in the liver of animals. It splits hydrogen peroxide into oxygen and water.

c. My results also matched my prediction regarding the amount of carbohydrates left after fermentation in the flasks. Based on my predictions, there should be more carbohydrates left in the experimental after fermentation since there was less alcohol produced. The lower percentage of alcohol suggests that there was less reactions that occurred, therefore causing less alcohol

Filtering, evaporating, centrifuging, and decanting something will only physically change it. Chromatography is used to separate different parts of a solution so that it can be identified. It can work because different substances have different attractions to things. Distillation can separate substances, such as salt water, as long as it has different boiling points. It can even be used to purify salt water but it is not cost efficient or energy efficient so it is not suitable for everyday use.

The results can be used to understand more practical applications, like human cells for example. the experiment is ineffective way of observing the effect of alcohol on cell membranes and is a good education tool. The study is

The Pros And Cons Of Gasoline
Distillation occurs at an oil refinery. At an oil refinery, the crude oil is heated in what is called a distillation column. At the distillation column, the crude oil is heated. As the temperature rises, different hydrocarbon chains boil off at different temperatures.
Lab Report On Fermentation
Joshua Miller 12/18/17 Fermentation Lab report Introduction The term fermentation refers to the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat (wikipedia). Sugars are converted to ethyl alcohol when fermentation happens. In this experiment we determined if yeast cells undergo fermentation when placed in a closed flask with no oxygen. Glucose and yeast are mixed together in a closed flask and allowed to incubate for about one hour.

For example, fermentation occurs in yeast in order to gain energy by transforming sugar into alcohol. Fermentation is also used by bacteria, they convert carbohydrates into lactic acid. Ethanol fermentation is done by yeast and certain bacteria, when pyruvate is separated into ethanol and carbon dioxide. Ethanol fermentation has a net chemical equation: C6H12O6 (glucose) > 2C2H5OH (ethanol) + 2CO2 (carbon dioxide). This process of ethanol fermentation is used in the making of wine, bread, and beer.
Beer In Ancient Times
For thousands of years, fermented beverages have been involved in human societies. Almost every culture has fortuitously discovered the potential for grain to be transformed into alcohol. The actual beginning of beer is concealed in the hazes of ancient times. It might be that a bowl of barley was left wide-open to some elements and was moisturized triggering the grain to germinate. Then, natural yeast settled on the surface of the resulting liquor and the fermentation process originated.
Fermentation Process In Yeast
Conclusions: The fermentation process was evident when the specific odor was emitted from the mixture. When yeast undergoes fermentation it produces alcohol and carbon dioxide, these substances were obvious in the smell. The budding, however, could only be observed under magnification so a microscope was needed. When observed under a microscope the buds were clearly evident when the yeast cells grouped together. The budding process could then be observed.

Rediet Legese iLab Week # 6 CRUDE OIL DISTILLATION Introduction: The aim of this week lab experiment is to experiment distill crude oil and to check how temperature determine the chemical properties of crude oil plus how the boiling point can also show physical properties. They are two major finding in this experiment. he first finding was the point at which the raw petroleum is heated to the point of boiling, at 275 0C, the gas and kerosene oil are refined, however the oil (lubricant ) stays as an unrefined feature oil.
Desalination Technology In Clean Water
The major processes may be grouped into two categories, which include thermal processes and membrane processes. Alternative processes include freezing and ion exchange (Shatat and Riffat, 2012). Thermal desalination Thermal desalinization is also referred to as distillation and consists of several processes. The method is applied to seawater and brackish water following principles of evaporation and condensation (Shatat and Riffat, 2012).
Essay On Desalination
The thermal distillation process uses heat to evaporate water and then later liquefy again. When there is leftover heat or enough electricity available, as is often the case with factories and power plants, thermal distillation is a well-organized and workable
Gas Chromatography In Alcoholic Beverages Lab Report
This method which uses an internal standard and flame ionisation detector, is exact and more specific than methods usually used. The gas-liquid chromatography method determines ethanol clearly and separately from the other beverage components that would have interfered in other methods, without any distillation or need for a chemical reaction. Determination of ethanol is one of the most vital routine analysis in a current winery. This method provides frequent, rapid and accurate results are needed to regulate the quality of the wine from grape to bottle, as well as for state and federal government
