Introduction Enzymes are an important biological catalyst that is absolutely crucial for life to exist. The ultimate purpose of this experiment was to examine enzymes and how they function in cells, explore the result that concentrations and environmental factors have over these functions, and lastly to read and interpret graphs related to enzyme function. This type of study had various parts, therefore there are various hypotheses. The first being, if it is potato extract, then it will contain…

Laboratory Techniques and Measurements Tiffany Abbe Introduction: In this lab I will be adapting more about how to utilize distinctive estimation instruments and comprehend the diverse procedures included. Figuring out how to ascertain temperature and length. Will likewise make estimations utilizing the SI frameworks for fixation, thickness, and volume. While having the capacity to reate arrangements of building so as to change focuses and densities as tock arrangement. Materials and…

Nutrient Testing Lab Purpose: Test different food items to see if certain nutrients are present. Hypothesis: if iodine, paper or certain solutions is present in the foods we test then it has one of the nutrients because it is detectable by a black, blue, yellow color when they are applied. Materials: flour, gelatin, milk, Iodine, brown bag, honey, cooking oil, potatoes, test tubes, peanut butter, eggs, paper towels, Chem-plate, hot water bath, Biuret's solution, Benedict's solution, chocolate…

This lab was a two week long lab called the Grignard Reaction lab. The purpose of this lab was to perform the Grignard reaction and to obtain the final product triphenylmethanol from a halide, phenylmagnesium bromide and the starting material, methyl benzoate along with the Grignard reagent. Bromobenzene, magnesium turnings, and anhydrous ether were needed to form the Grignard reagent. To synthesize the reagent, react the reagent with methyl benzoate to form a tertiary alcohol. The objective of…

Formula of a Hydrated Salt 2.Objective- We are trying to figure out the formula of a unknown hydrated salt. In order to do this we must know the formula to calculate moles which is moles=Mass(g)/Molecular Weight. 3.Introduction- We must know about hydrated salts which are salts that contain water. We are trying to figure out the molar mass of the hydrated salt given to us. In order to do this we must heat up a hydrated salt so that it reverses the reaction and removes the water.We then are…

After the experiment was conducted and the data was analyzed the cation in the solution was proven to affect the color of the flame. The cation in each of the solutions are calcium, copper, lithium, and potassium. The two salt solutions that have calcium as its cation are Calcium Chloride and Calcium Nitrate. When you compare those two solutions you can see that both of their flames turned orange. The two salt solutions with chloride as their anion were Calcium Chloride and Lithium Chloride.…

Reflective Essay: Cover Letter In Chemistry Lab 1 a theme that stood out to me and impacted how I learned was the connection of the lab and the lecture. This theme specifically impacted my learning, since when we would cover a concept in the lab that I was unfamiliar with the following time in lecture we would cover that concept. A specific example where we covered a concept in the lab, however had not covered in lecture was molecular geometry. Learning about this concept before proceeding into…

Preparation of the sample The sample must be prepared for testing by: • Dissolving the solution in distilled water • Filtering the dissolved solution • Evaporating the water to increase the concentration Equipment 1 beaker 50ml of distilled water Stirrer 1 Funnel Filter paper 1 crucible 1 Bunsen burner 1 heatproof mat 1 tripod 1 teaspoon of soil sample 1 conical flask 1 Pipeclay triangle Method 1. Place the soil sample in the beaker and add 50ml of distilled water and stir until…

Objective The objective of the experiment was to determine the purity and components of a mixture of fluorescein and bromonitroindoline, as well as separate them, through the process of thin layer chromatography. Procedure Part A- Separation of Compounds by Thin Layer Chromatography • Three 100 mL beakers and watch glasses were cleaned in preparation for this experiment. Three silica gel plates were acquired from the instructor, and to each plate a line was drawn 5 mm from the edge of the…

The purpose of these calculations is to identify the limiting reagent and calculate the percent yield of the esterification reaction used to produce aspirin. This reaction was catalyzed by concentrated H2SO4, but since it is not consumed during the reaction, it does not affect the stoichiometric calculations. In order to determine the limiting reagent, the moles of reactants were calculated (Part A). Part B of the calculations illustrates the amount of aspirin produced by each reactant based on…
