Chemical reaction

Enzymes are a substance mostly known as macromolecular biological catalysts. These substances are produced by a living organism that kind of acts as a catalyst to bring a reaction to them. Enzymes have occurred more than 5,000 years ago, as humans stored milk in animal stomachs, which happened to contained enzymes that turned the milk into cheese. The process begins when substrates, the molecules in a cell, are converted into new different molecules from the enzymes, these are known as the products

only one reaction, 99 as AgNO3 was not a fully supported result yet; further reactions would have to be considered. Next, the chemical reactions were written out to determine

Group 12 Topic: Balloon Race (Reaction vs. Temperature) Due Date: 6 October 2017 Science Fair Assignment (2) Background Research The topic is Balloon Race (Reaction vs. Temperature). In this experiment, the scientists will be analyzing on whether temperature affects the rate of a gas producing reaction. The independent variable would be the temperature of water in degrees Fahrenheit, while the dependent variable is the rate of reaction which is caused by the rate of carbon dioxide

attain a better understanding of enzyme activity by timing chemical reactions in certain temperatures and pH levels. Enzymes act as catalysts that help speed up reactions. Without these enzymes chemical reactions in metabolism would be backed up. There are two factors that affect an enzyme’s reaction rate: temperature and pH levels. In this label we will be testing different pH levels and temperatures to see which ones cause the most reactions. Our team was given the temperature of 37 degrees celsius

Thermo catalytic Degradation of Waste Polythene into lubricants using Zeolite Mr. Amol Vagad Department of Instrumentation Engineering, MCT’s Rajiv Gandhi Institute of Technology, Mumbai, India amolvagad@gmail.com ABSTRACT: Waste polythene primarily in the form of used polythene bags, comprises of most of the plastic pollution caused in India. Many processes have been developed to combat this issue which includes pyrolysis and catalytic cracking. This paper states an experiment that was

In this lab the effect of the enzyme concentration has on the speed of the reaction will be observed. The amount of oxygen gas produced will be measured to determine the reaction rate. If the enzyme concentration increases then the reaction rate will also increase. The measure of how fats oxygen is produced will be how long it takes for the filter paper disk soaked in different concentrations of catalase to rise to the top. If catalase is exposed to boiling temperature then it will denature. Catalyst

entropy (ΔS) of the potassium nitrate’s (KNO3) dissolving reaction are determined by finding the equilibrium constant (Ksp). After this experiment is performed one should be able to have a better understanding of the thermodynamic properties and solubility constant (Ksp), and those properties relation to ∆G˚. Thermodynamics is the study of hat energy and other values of work, temperature, and energy regarding the process of a chemical reaction. A goal of this experiment is to be able to measure the

For this station, Ms. Tan carried out the experiment using only sulfur. When the sulfur was heated by the Bunsen burner, we observed sulfur undergoing a chemical change. While burning, Sulfur turned from its original colour to a more orangey/red colour then turned darker to eventually black. D - #5: What can you say about the relative melting points of the two substances? Through further research, we discovered

Introduction Enzymes can be characterized by 2 fundamental properties which are, they alter the rate of chemical reactions by increasing it without being consumed or permanently altered. The second is that they can successfully increase reaction times without altering the chemical equilibrium between products and reactants. When using yeast, we monitor how it reacts with other items. It is used in the fermentation of beer and wine as well as the rising of bread. Yeast is a living organism and some

all oxidation-reduction reactions. 6. The balanced chemical equation for the electrolytic decomposition of water to its elements is: 2H2O (l) → 2H2 (g) + O2 (g) 7. 2H2O → O2 + 4H+ + 4e- 2H2O + 2e- → H2 + 2OH- 8. The oxidation and reduction half-reactions may be combined to give the balanced chemical equation for the decomposition of water. This can be done by multiplying the reduction half-reaction by 2 so that there are 4 electrons in total for the half-reaction. The electrons in the oxidation
