Oxygen toxicity

buffer throughout the experiments conducted. This was done to observe the effect different levels of pH buffers have on the breakdown of hydrogen peroxide and the volume of oxygen released. The results from the majority of experiments conducted reflect that though they are in consensus with the hypothesis that the volume of oxygen will be at its highest at pH 7, it was found that the temperature of hydrogen peroxide and the batch of catalase may have varied which affected the precision of the…

Chlorine is a chemical added to swimming pools to keep the water free of bacteria and algae. Chlorine levels in swimming pools vary based on how much chlorine has already been used to remove bacteria and how much sunlight has broken down the chlorine molecules. This means that pool owners spend a lot of time testing and adjusting the levels of chlorine in their pools. To reduce the amount of time spent on pool maintenance, pool chemical manufacturer's created chlorine tablets. These tablets are…

Merriam-Webster defines hypothermia as a condition in which the temperature of the body is very low. This condition is a medical emergency that occurs when the body loses more heat than what it is able to produce; hence, the body temperature decreases. The part of the brain called the hypothalamus is responsible for controlling body temperature; therefore, hypothermia is the result of the dysfunction of the hypothalamus. In order for a person to become hypothermic, their body temperature must be…

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…

heart can no longer keep up with the normal demands placed on it to pump blood to the rest of your body. Blood miscommunications is another type of CHD that can cause the blood to go to other parts of the body. This can be fatal because blood carries oxygen and nutrients to your body's tissues and it takes carbon dioxide and waste products away from the tissues. It is also needed to sustain life and promote the health of all the body's tissues. Congenital Heart Disease has many therapeutic…

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…
