Oxygen therapy

Conclusion: The the precipitation reactions lab eight out of the fourteen occurring reactions were precipitates. A precipitate means that a solid substance was formed or a substance that is not aqueous was formed. The reactions that did not form a precipitate were DNR, which means that they did not react. At station one barium chloride and potassium nitrate did not react but barium chloride and silver nitrate reacted to form barium nitrate and silver chloride. The precipitate at station one was…

through oxidative phosphorylation which a small amount of input from glycolysis. The main substrate source for prolonged exercise is fat from adipose tissue. Oxygen is essential to cellular…

collect plankton and benthos specimen that were put in a specimen jar. A water sample was collected to measure the dissolved oxygen in the water, phosphate in the water, nitrate in the water and the hardness of the water. Three hach kits were used to measure three different properties of the water of the stream. The Dissolved Oxygen hatch kit was used to measure the dissolved oxygen in the water. The Nitrate hach kit was used to measure the Nitrate (NO_3) in milligrams per liter. The Phosphate…

Introduction The Objective was to determine the mass percent composition of the mixture using a chemical reaction and stoichiometry mixture Na2CO3 and NaHCO3. To do the lab by using the constant mass. Constant mass is a quantitative chemistry technique where a single chemical species or group reactants is heated with constant weighing until the mass does not change. After heated the Na2HCO3 will undergo a decomposition and Na2CO3 will not undergo reaction. The balanced equation is…

The estimated amount of time it took for the reactions that involved 2- chlorobutane, 2 – bromobutane, or 2 – chloro – 2 – methylpropane and 2 - bromobutane to form a precipitate could not be determined because no precipitate was formed. It makes sense that no precipitate was from because there was a lot of steric hindrance. The estimated amount of time it took for the reaction that involved 1 – chlorobutane could not be determined because at first glance it looked as if no precipitate formed.…

In our compost chamber one of the most prevalent features throughout the check was the presence of slime mold. Slime mold seeks out decaying materials such as wood and leaves to grow on, so it can take up the nutrients. Slime molds are organisms that reproduce with spores, so the rapid spread everywhere in the chamber was one that closely resembles its characteristics (Poinar 1). Slime mold engulfs fungi which is attracted to decayed material, therefore it is reasonable that the slime mold would…

http://www.sunriseopals.com Buying Opal Jewellery Opals are intriguing and delightful stones; however it can mistake looking for them. What is the distinction in opal jewellery between stone, doublets, and triplets? Is the smooth light stone more profitable then the dim green? What hues would it be advisable for me to search for? Here are a couple tips while picking opal: • Australian opal is by and large the best and where the greater part of the universes opal supply originates from. This is…

Deforestation in the Amazon Did you know that it is said that within 100 years, there will be no more rainforests? The rate of deforestation is the same as the loss of thirty-six football fields every minute. One and a half acres of forest is cut down every second. Although it allows for people to generate more revenue, deforestation should be banned because it creates more carbon dioxide in the air, promotes the development of drought, contributes to the extinction of wildlife and is a limited…

This disagreement was about the pigments located in the stems and veins of a plant and the pigments located in the green portion of a leaf. Jan believed that only the stems and veins contained all of the important pigments except for chlorophyll. She believed that the green portion of the leaf would not contain all these other pigments. Mark, on the other hand, believed that the same pigments were also located in the green portion even though they were not visible. In order to determine who was…

The purpose of this experiment was to ascertain an unidentified substance. The substance in question was a colorless liquid with an odor resembling acetone. To start with the Tollens’ test was conducted on the unidentified substance to differentiate between an aldehyde and a ketone. The results of the test were negative. This indicated that the substance under consideration was a ketone The next step consisted of determining the melting point of the substance, which was in the range…
