Chemical reactions

certain chemical reactions to take place much quicker than reactions would occur on their own. Enzymes function as catalyst, which means they speed up reactions by providing an alternative reaction pathway of lower activation energy (cite). Each step of a pathway typically requires a specific enzyme, without the specific enzyme, the pathway can not be completed. In addition, enzymes do not undergo permanent reactions and remain unchanged by the end of the reaction. Enzymes catalyze chemical…

oxalyl chloride and hydrogen peroxide glow stick was patented in 1960’s. Chemiluminescence is a luminescence resulting from a chemical reaction which is how glow sticks work. A glow sticks has a glass vial, a small glass or plastic bottle for holding medicines, and you break the glass by bending the stick. This then causes the chemicals in the stick to mix and a reaction takes place. This experiment will test the length of time glow sticks radiate in different temperatures. Test if the stay lit…

identity of an unknown ionic compound, unknown sample 3, through the substance’s chemical properties and reactivity. This compound was discovered in a landfill and we needed to know as much information as we can about how the chemical will behave in different situations so that the city will not be negatively affected by the chemical.2 Thus, we first needed to identify the unknown substance, determine some of its chemical properties and reactivity, and also its synthesis.1 To accomplish this…

explore how different factors affect the reaction rate of enzymes reacting with their corresponding substrates in order to learn more about how enzymes function in different environments. The independent variables investigated in this experiment were the concentration of different substrates, the temperature of the environment, and the effect of a catalyst on the reaction rate. The dependent variable for all of the investigations was the time it took for the reaction to occur. To investigate…

Introduction: In this lab, I determined what type of reactions could be performed based off of experiments. Six experiments were chosen out of twelve. These six experiments were chosen based off of what Green Chemistry Principle(s) they followed. The purpose of this lab was to perform each experiment correctly and according to the Green Chemistry Principles. There were four parts to this lab. The first part was to familiarize myself with the Bunsen Burner by sketching it out in my laboratory…

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…

principles 2.1 Chemical vapor deposition 2.1.1 Definition of chemical vapor deposition Chemical vapor deposition (CVD) is a versatile process which is widely applied to produce coatings, powders, fibers and monolithic components [1]. Applying the chemical vapor deposition, it is possible to produce alloy and compounds of metals and nonmetal materials. Chemical vapor deposition can be defined as the deposition of a solid on a heated surface from a chemical reaction in the vapor phase [2].…

We get the energy to do things from a chemical reaction in our body that requires food molecules and oxygen. Food molecules and oxygen are generated by plants in a process called photosynthesis. We eat food and breathe in oxygen. The larger food molecules become subunits (such as glucose) in a chemical reaction called breakdown. Finally, our bodies use oxygen and glucose in the cellular respiration process to generate energy for our cells. Photosynthesis is the process in which plants get…

Abstract:- The experiment illustrates the relationship between the limiting reagent and the amount of product produced as a result of a chemical reaction. The chemical reaction was carried out by mixing the solution of Na2CO3 and CaCl2 and the precipitates of CaCO3 were obtained as a product. The experiment was carried out in 4 trials in order to determine the limiting reagent and the actual yield of the product obtained. In the first three trials, Calcium Chloride was the limiting reagent and…

The Chemical Reaction Between Ammonia And Bleach Marie Holloway Walden University 09/14/2017 The Chemical Reaction Between Ammonia And Bleach According to the BBC News (2011) Fritz Haber, a German Jewish scientist, who studied the thermodynamics of gas reactions, discovered the potential for fixation as a result of synthesizing chlorine and ammonia into a…
