Aim To find out the difference of reaction time it takes for the baking soda when it meets the vinegar under the condition that the volume of the vinegar changes. Background Information The two reactants‚ which are baking soda and vinegar‚ react with each other. Then it creates product‚ carbon dioxide‚ water and sodium acetate. The chemical name of vinegar is ethanoic acid and baking soda is sodium hydrogen carbonate. To illustrate this phenomenon as a chemical equation‚ it can be shown as C_2 H_4

Microbes are everywhere. Objectives: The experiment performed in the Lab was isolation of microbes taken from us and the environment. We used Nutrient Agar which is a growth medium used to culture microorganisms or small plants and Sabourand Dextrose Agar plates used to cultivate moulds and yeasts. The objective of it was to demonstrate that microbes are everywhere. We expected to find a variety of bacteria‚ moulds and yeasts. We were introduced to aseptic techniques as they help ensure that

Design Experiment to investigate the effect of the concentration of Sodium Hydrogen Carbonate on the rate of photosynthesis using Cobomba plant. Aim: The aim of the experiment is to investigate the effect of the concentration of Sodium Hydrogen Carbonate (NaHCO3) on the rate of photosynthesis using a Cobomba plant. Hypothesis: As the concentration of NaHCO3 increases the rate of photosynthesis of the Cobomba plant should increase‚ as there is a greater presence of a carbon dioxide‚ obtained

Carbohydrates come in a variety of sizes. Describe the basic chemical structure of carbohydrates and explain how larger ones are made. How do the category names of different carbohydrates relate to the complexity? Finally‚ what are they used for in organisms? Carbohydrates are made by the basic chemical structure of Carbon‚ Hydrogen‚ and Oxygen‚ in the same two to one ratio that makes up water. It is made bigger when an enzyme comes in and takes hydrogen and oxygen away from two different

Abdulaziz Design Lab Report Research Question: How is the rate of yeast fermentation of 7.5g of yeast affected by using different companies of yeast (Bakon Yeast Inc.‚ Lake States Yeast LLC‚ Lesaffre Yeast Corp‚ Red Star Yeast Company‚ and Minn-Dak Yeast CO Inc.)? Background Information: Yeast is a fungal microorganism that is used to manufacture mainly bread and beer. It reproduces rapidly. Fermentation is the process by which yeast takes in sugar and releases alcohol and carbon dioxide

so many conspiracy theories speculating it is hard to define the story behind Christmas and when exactly it took place. We assume that Christmas is on the 25th‚ but like other historical events‚ these become manipulated. Resulting in change. As a result Christmas should be banned dies to not enough supportive evidence. On the other hand Christmas should be banned because of its traditional values‚ of the food we eat‚ the gifts we receive and the time we spend with our family. But now the presents

Respiration-Fermentation in Yeast Aim: To study the different of solution affect the gas forms during fermentation in yeast. Procedure: Refer to Lab manual Result: Questions: 1. Yes. 2. Sucrose. 3. When no oxygen the ATP will be produce. 4. Brewery. 5. Aerobic glucose and aerobic glucose oxygen. 6. CO2 and aerobic water. 7. CO2 and aerobic ethanol. Conclusion: The purpose of this experiment is to determine sucrose gas form during fermentation with yeast is the most CO2. Sucrose

MY LAI MASSACRE AS A RESULT OF OBEDIENCE TO AUTHORITY The Vietnam controversy made many people feel at distress. It was never considered a "war‚" although that is exactly what it was. The My Lai Massacre in Vietnam was one of the many atrocities of that war. There is an unquestionable connection between Milgram ’s "Obedience to Authority" and the My Lai Massacre. According to Kelman & Hamilton‚ "Unquestioning obedience has been the cause of such disasters as the My Lai massacre and the Holocaust

Master thesis Philosophy of Behavioural Sciences Moral Judgements and motivation: how do they relate? Claudia Jansen Supervisors: Prof. Dr. Jan Bransen Drs. Dorothee Horstkötter The most important thing about the practice of focus is that it cannot be forced. Trying hard to concentrate‚ doesn’t work. It produces frustration‚ tiredness‚ and narrowness of vision. Focus follows interest‚ and interest does not need coercion. A gentle hand on the steering wheel of attention will suffice -Timothy

History of Baking The History of Baking First Baking Course Ever Find Some Grain‚ a Mortar‚ and a Pestle Way back in the year 8‚000 B.C.‚ some clever dudes in Egypt started crushing grain with a mortar and pestle. You can bet they were surprised when after a few twists and grinds‚ a German chocolate cake appeared. Just kidding. They only managed to make a rudimentary form of unleavened bread sort of like a Mexican tortilla--but it was still a pretty big accomplishment. They shared this information
