The line of best fit gives the respiration rate of day-old seedlings as the concentration of NaCl they are exposed to increases. As NaCl Concentration increases the rate of cellular respiration decreases by .108 ppm CO2/g per second. This overall decrease throughout the data further supports our hypothesis. Discusion: The data collected in the experiment does support our hypothesis.
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.
The control to this experiment would be a open container with the same amount of Daphnia and observed for the same amount of time. There would also be a container with certain levels of oxygen concentration that would be observed. The independent variable of this experiment is the oxygen concentration in which the Daphnia will be placed in and the dependent variable of the experiment is the hemoglobin produced in the Daphnia. It takes an estimated two to three days for daphnia in hypoxic conditions to appear red, so the colors of the organisms would be observed for multiple days in order to see the whole process of hemoglobin synthesis in Daphnia. The effect of oxygen concentration on the hemoglobin produced in Daphnia will be tested by placing saran wrap over the petri dish in which the Daphnia live in with varying amounts of openings and measuring the amount of Daphnia that appear red due to the hemoglobin produced in it’s
The procedure for this test included using Schindler-Patalas traps that were lowered into the water to collect water at various depths. This particular contraption was made out of a Plexiglass box with hinged doors on either end. The doors allowed for the water to flow through the box so it could sink properly, then contain the water when it was pulled back up to the surface. Once the box was resurfaced from its various depths of 50 cm increments, the doors would close and the sample would be filtered through a sample bucket with a plankton filter. The remaining sample in the filter was then placed in a labeled container for said depth and saved for viewing and testing later.
While CO2 is produced, the amount of CO2 produced is different depending on the organisms, in this case crayfish. To test the changes in pH, NaOH is used to neutralize the carbonic acid produced by the crayfish, by which the
Objective: The purpose of this lab is to show the relationship between chemical decomposition and exothermic reactions, as well as applying the scientific method. This is shown through the construction and launching of popper rockets. Introduction: Crucial things to know are exothermic reactions, Scientific method and chemical decomposition. The scientific method is a series of steps used by scientists to solve a problem.
We also collected quantitative data for the aquatic chamber. We collected how much dissolved oxygen in the water, the pH of the water, and the water’s temperature. It was Billy’s job to collect the temperature of the water and how much dissolved oxygen there was in the water. To find the temperature of the water, Billy used a temperature probe that could be put in the water and placed it into the water. Billy then used a special probe that measures the dissolved oxygen and placed it into the water to get the amount of the dissolved oxygen.
As carbon dioxide is blown into the beaker through the straw the pH level lowers. The universal indicator showed that the added carbon dioxide turned the pH level acidic. If the pH level in the ocean drops to acidic marine life can be harmfully affected. Coral bleaching and the weakening of calcium carbonate shells are both affects of the increase of acidic pH levels. When testing how the pH level affected the shells, we knew a reaction was according due to the bubbling of the shells.
This deprivation of oxygen caused by the pollutants will cause many of the aquatic plants to
Lettuce: (10-5)/25 = 0.2 Poinsettia: (0-0)/25 = 0 What was the role of the sodium bicarbonate in this experiment? The sodium bicarbonate provides carbon dioxide necessary for the photosynthesis process.
An easy synthesis of 5-trifluoromethylated oxazole compounds as a building block which would be able to transform into effectively useful pharmaceuticals or chemicals can be achieved to improve the practical use. In this study, we describe the new synthesis of methyl 5-trifluoromethyl-2-phenyloxazole-4-carboxylate which derived from 4-alkoxy oxazole in one-pot by utilizing Cornforth rearrangement. At this time, we took an interest in the experimental result that no precursors of rearrangement were detected in this reaction. The strategy of designing and synthesizing compounds that inhibited reclosure from nitrile ylide resulted in successful capture of unstable precursors.
I did not expect for the plants to actually absorb the acidity from the water and become acidic itself. My research was confirmed that the plant would break down and die because about two weeks with the plant sample in vinegar the leaves lost their opacity and color. The lab results involving the vinegar as ocean water substitute was pretty accurate to all the research that I found about calcium carbonate animals and ocean plants. Ultimately both broke down in their own ways and the acidity wore down the samples very quickly.
Before proceeding with the experiment, the theoretical yield was calculated to be 0.945 g. After preparation of the product, the theoretical yield was used to determine the percent yield, which was found to be 79%. Due to this reasonable yield, it was concluded that the synthesis of methyl orange had been successful. Data Table 1 gives the results and observations that were recorded throughout the preparation of methyl orange. According to literature, methyl orange is an azo dye that forms orange crystals. However, the product that formed was orange with gold crystals.
Oxygen is released during the day and taken in at night through the stomata, which are small openings on the surface of the leaf. Oxygen is used to measure the rate of photosynthesis. The aim of this experiment is to observe the effect of light intensity on the rate of photosynthesis by seeing how many bubbles are
Ever since the industrial revolution commenced, around one third of the carbon dioxide released by human interference has been absorbed by the ocean, which is one of the reasons of the drastic change in climate as well. Without the ocean absorbing carbon dioxide, the carbon dioxide n the atmosphere would be drastically higher, with possibly increasing the levels of climate change. The point of the research is to see how will the pH affect the organisms in the marine ecosystem and does carbonation affect an organism’s mass and form. Many organisms that are part of the marine food chain are going to be affected by ocean acidification due the levels of acidity deteriorating the calcium carbonate within the animal. It turns out
