does in fact affect the productivity/ ability to speed up chemical reactions. The faster catalase could break hydrogen peroxide into oxygen and water the faster that it could speed up chemical reactions in the bodies or organisms. The results, at first may seem dry, but they demonstrate how crucially important it is we know what the optimal pH is for enzymes like catalase. This knowledge allows us to understand better our bodies, and the chemical reactions inside it, as well as enable us to…
The solubility rules were used to determine which reactant was aqueous and which one was a solid. The solid is the precipitate formed in the reaction. The formation of the precipitate indicates that a chemical reaction occurred. If no precipitate formed the reaction would be labeled with DNR, which stands for does not react. The solubility rules states which elements are soluble or insoluble, including the exceptions for each rule. For example at station…
What does an award mean to a person? An award could mean a person was successful; such as, moving to the next step in a career. A reward could also mean recognition for a simple action given; such as, showing up to class. These rewards for showing up to class, one may feel that these are participation trophies. While participation trophies may boost a child's self-esteem, children grow up believing goals in life are easy to come by and no matter how hard they try, they still receive credit;…
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.…
Ammonia, NH3 10 was added to a test tube and 10 drops of 0.5m CuSO4. The result was recorded as the rest of every trial in the experiment with the different chemicals. 10 drops of 1M Na2CO3 was added with 10 drops of 6M HCl. Bubbles were formed with no color in both solutions. The 10 drops of 5.0M Na2SO4 to a test tube was dropped and 10 drops of 1M HCl as the solutions were mixed white precipitate was resulted…
(2008, November 11). Without Enzyme, Biological Reaction Essential To Life Takes 2.3 Billion Years. Retrieved January 31, 2017. The basic concept that is being explored are about enzymes. Enzymes are proteins that are known for being sparkplugs in a chemical reaction. Enzymes have a shape and for them to ‘spark’ they must have the proper substrate for it to work U. This does not change the enzyme’s makeup but instead gives a resulting product. The shape of the enzyme is connected in relation to…
exceedingly complex system that is vital for the survival of species. What if the sodium channels were blocked when there is an impulse or stimulus present. In this lab experiment, we will find out how two chemicals, Lidocaine and TTX, affect sodium channels and action potentials. Both of these chemicals bind to sodium channels, and prevent sodium from entering the neuron and provoking an action potential. This lab experiment will contain a neuron with two electrodes applied in two places. These…
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…
Abstract: Using the PhysioEx.9.1 software, I ran Activity 4: Simulating Filtration lab to learn about the filtration of solutes in a membrane system. This experiment was conducted using four solutes: NaCl, urea, glucose, and powdered charcoal. The goal was to learn if any of these solutes passed through the three different dialysis membranes at varying pressures. Does increasing the pore size increase filtration rate? What effect will pressure have on the filtration rate? These are the…
newly discovered element with an atomic number of 24.5. Due to its placement on the periodic table between Chromium (24) and Manganese (25), it is believed to have a similar atomic and electronic structure to these two elements, and hence similar chemical properties. This means that Chromium or Manganese can be used…
