Organic Lab Trial 1 Trial 2 Trial 3 Observations We added the 30ml of warm water with 4.7 grams of borax powder in to the cup labeled ‘Borax Solution’ and also added a few dots of green food coloring. We then stirred it until all the solutions were completely mixed. When this happened the borax and water turned into a watery green solution. then we added 15ml of glue in the cup labeled ‘Ball mixture’ and added the mixture we made

Determining the Catalytic Properties of the Enzyme Peroxidase Extracted from a Turnip Under the Conditions of Temperature‚ pH‚ Boiling and Competitive Inhibitors By Robin Caserta BIO 101 September 30‚ 2013 ABSTRACT The enzyme‚ peroxidase‚ extracted from a turnip was tested for its efficiency in binding to its substrate and its stability under several conditions. To do this‚ we tested effects on peroxidase activity‚ first‚ with different amounts of the enzyme‚ next at temperatures of

The main purpose of this lab is to explain what emulsifiers and emulsions are and how emulsifiers affect emulsion stability. An emulsion is a mix of to or more liquids that usually do not mix together. One liquid is evenly dispersed in small droplets throughout the other liquid. Many emulsions contain water as one of the phases. There are two different types of emulsions. One type of emulsion contains oil droplets that are dispersed within water. It is considered oil in water emulsion. The other

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

Experiment 42: Ferrocene Preparation Introduction: The purpose of the lab is to prepare ferrocene from ferrous chloride and cyclopentadiene. Ferrocene‚ an organometallic‚ is a combination of two cyclopentadienide ions with a ferrous cation‚ such that the six pi electrons binds every carbon equally to the metal forming a sandwich type structure. Ferrocene has the properties of both an activated benzene (undergoes electrophilic substitution reactions) and a ferrous ion (oxidation reaction). Glyme

Halobacterium Lab Investigation Mason Pirio 12/12/13 Period 5 Table Group 3 PS 2- Experiment Design PS 3- Conclusion Writing PS 13- Nitrogen Cycle Abstract- In this experiment we tested to see how well halobacterium grows in different levels of salinity. We found out that the higher salinity in the growth medium the better the halobacterium grows. Background Information- Halobacterium is a bacteria that is found in the great salt lake. Halobacterium is an extremeophile which means it thrives
