Tyler White CHEM151LL 32658 04/01/2018 Different Types Chemical Reaction Types and Equations Purpose: The purpose of this lab experiment is to examine different types of chemical reactions such as Decomposition reaction, Synthesis reactions, Combustion reactions, and different Chemical equations. The experiments were conducted online using Late Nite Labs. Materials: Because the experiments were conducted online there wasn’t any physical use of materials, only digital ones, for these labs to be performed. Only the registration for the website was needed to perform these online labs, as well as a desktop computer.
Name: Avishak Deb Roy Partners: Leevell Penn, Varugh, Butler Bio 101 Lab Report #1 02.22.2018 Swimming speed of paramecium tetraurelia in different levels of treatment. Introduction Paramecia is a unicellular Protista which are naturally found in aquatic habitats. It is easily cultured in the laboratory. It is oblong shaped and covered with short hairy structure called cilia. Paramecia does not pose any health or ethical concerns and the population can be maintained if there is a food source such as Enterobacter (Biological Foundation 7).
Results Continued: The purpose of this experiment was to show the transformation of E. Coli with pGLO. We made four different plates each with different additives to compare them to one another, and be able to track the transformation. Initially we had predicted that only one of the four plates would glow. The plate with the plasmid (+pGLO)/LB/amp/ara was the one we said would grow and glow because it contained all the necessary tools to do so.
On the first negative control plate, there should have been no growth on the plate with agar and ampicillin and regular E. coli cells. On the negative control plate with just agar and E. coli cells there should have been growth but the colonies would not
1. What was your theoretical yield and your percent yield? Theoretical yield: 3.9151 g Percent yield: 79.30% 2. An accurate percent yield must be below 100% Why?
The mechanism that is compatible with the rate law that is calculated is rate=k[I−][S2O8^ 2-], which matches with the b) mechanism. It starts with the slow step, which is the rate determining step and it also states that the rate law equals to rate=k[I−][S2O8^ 2-].
coli bacteria new traits. The pGLO plasmid that is being transformed into these cells contains genes that can give colonies of bacteria the ability of antibiotic resistance and a green fluorescent glow. Four different models were prepared and plated on multiple agar plate. After the bacteria was grown for three days in an incubator at 37°C; observations were made and recorded (Table 1). All of the plates were looked at for the amount of colonies grown, if growth was present, and if the colonies gained the ability to glow green.
Describe how you walked for each of the graphs that you match. Part 2: #7 Graph: To achieve the graph given, start one meter away from the motion detector. Then, in the time span of two seconds, walk farther away from the detector to approximately 2.5 meter and land there exactly at three seconds after beginning to walk. Then, walk towards the motion detector to 1.7 meters away from it in 1.5 seconds.
Major unknown #202 was given out by the instructor, and the unknown bacterium was streaked out on a Trypticase Soy Agar tube and plate to inoculating the bacterium and incubating. After incubated and grown the morphology was observed and several Gram stains were performed to determinate if the bacterium were gram positive or negative, and the morphology of the bacterium. The Gram Stain of my major unknown #202 was determinate to be Gram negative bacilli, and was double checked by the Gram check slide. Also I noticed that my bacterium was a facultative anaerobe and according to my results of endospore test, my bacterium has not endospores. So according to the list of possible major unknowns provided by the instructor, I narrow my bacterium thru
The purpose of this lab was to test the effect of pollution on algae growth. Through a series of experiments that lasted a month, four of the six hypotheses were proven to be correct or partially correct. The first hypothesis stated that if 0.5 mL of salt was added to algae, then the algae would grow slower than the positive control. This was proven correct, as shown by the difference of the data from the positive control and the container with 0.5 mL of salt in it.
Title: THE BALLOON INFLATION REACTION Introduction: Chemistry is one thing that makes us understand and gives us reasons of why certain reactions gives certain results. In this experiment we will be illustrating the reaction between baking powder and vinegar and see what happens to the balloon that is attached to it. Hypothetically the reaction of the vinegar and baking powder will produce carbon dioxide which will inflate the balloon. If the more vinegar may happen that when more vinegar is added to the baking powder it may produce more carbon dioxide thus the balloons diameter increases.
Background Information The purpose of this experiment is to monitor how different plant species affect photosynthesis. To measure how the different plants affected photosynthesis, we measured the levels of carbon dioxide. The question that we researched was: How will different types of plants affect photosynthesis and rate of respiration? We believe that if cedar is placed in the chamber and undergoes photosynthesis then the carbon dioxide levels will go decrease the most because the most photosynthesis will occur.
Investigation of Hardy-Weinberg theorem and evolutionary mechanisms Madison Gladden 03/04/2016 Genetics Dr. Yamashita Introduction: The change in allele frequency in populations over time is an observable sign of evolution. These changes in allele frequency can be measured in a population.
The doubling time refers to the time a cell requires to double the amount of its original population numbers. However, it is arduous to comprehend the factors underlie within the cell, peculiarly in the determination of the cell proliferation rate and doubling time of a cell. It is inconceivable to have a similar proliferation rate and doubling time across the organisms. Proliferation rate and doubling time of a cell often affected by the complexity of a cell. For instant, when comparing two unicellular organisms, such as yeast and bacteria, S. cerevisiae shown to have a much slower proliferation rate (100 minutes per generation) as compared to E. coli, which proliferation rate is 15 - 20 min per generation (Herskowitz, 1988).
Lab Report Experiment 6 Rates of Chemical Reactions By Nikhola Mirashirova Lab Partner: Dina Abetova Section 3, Saturday October 31, 2015 Introduction Rate reaction is the measure of the change in concentration of the reactants or the change in concentration of the products per unit time.1,2 Rate law for this experiment: Rate = k(I-)m(BrO3-)n(H+)p There are several factors which affect the rate of reaction: catalyst, reactant concentration, and temperature.1,2 A catalyst is a substance that changes, increases or decreases, the rate of a chemical reaction but is not being used up during the reaction.3 It provides an alternative way, so that the rate of reaction changes.4 Catalyst, which is used in this experiment, is (NH4)2MoO (0.5 M).
