Determination of a Rate Law and Temperature Dependence of a Rate Constant By Marvin Coleman March 7‚ 2011 Abstract: From the shown calculations & graphical analysis‚ the experimentally determined rate law is rate = K[I-].969 [H2O2].991 and the experimentally determined activation energy is 59.50 kJ/mole. Introduction: The rate of a reaction varies at different temperatures and reactant concentrations. In this experiment‚ the orders and dependence of the rate constant of the products

Practical 4 Determination Of Fruit Firmness Introduction The development of sensors to measure fruit internal quality variable is one of the challenges of post – harvest technology. Several variables can currently be measured‚ including sugar content‚ firmness and internal disorders. Fruit quality is related to both internal variables (firmness‚ sugar content‚ acid content and internal effect) and external variables (shape‚ size‚ external defects and damage). Increasing consumer demand for high

Acid-a chemical substance that neutralizes alkalis‚ dissolves some metals‚ and turns litmus red; typically‚ a corrosive or sour-tasting liquid of this kind. How does acid clean copper- “The oxygen in the air and the copper in the pennies form an oxide that coats the pennies and makes them look dirty. The acids break the copper oxide free from the penny. As we have seen experimentally‚ acid alone does not clean as well as acid and salt.” Can acid kill you?-”The actual causes of death however are not

analyze data and draw a conclusion. In this experiment I will find out that in a type of water the Alka-Seltzer will dissolve faster and slower. Alka-Seltzer is one of the world’s best known antacids. Its main function is to absorb excess stomach acid. II. MATERIALS: * Tap Water - Warm Water * Cold Water - Salt Water * Acidic Water -5 cups (250 mL of water in each cup) * A whole Alka-Seltzer tablet III. HYPOTHESIS: My hypothesis is that the Alka-Seltzer tablet

The Effects of Acid Rain Bio-105 Abstract The effects of acid rain is damaging no matter how you look at the picture. Acid rain effects open areas more than forests due to the trees blocking some of the rain from hitting the ground. Acid rain is monitored by using emissions monitors. This helps figure out how much acid is in rainwater. Acid rain is harmful to fish by killing off entire species. Acid rain is harmful to living creatures‚ but many do not realize how toxic it can be to

Acid-Base Titration Background Information A titration is a controlled addition of one substance into another substance. In an acid-base titration‚ the experimenter will add a base of known concentration to an acid of unknown concentration (or vice-versa). The goal of the titration is usually to use the substance of known concentration to determine the concentration of the other substance. In order to run a titration‚ the following materials are needed: • A buret filled with the base (or acid) of

PROPERTIES OF SOLUTIONS A solution is a mixture of materials‚ one of which is usually a fluid. A fluid is a material that flows‚ such as a liquid or a gas. The fluid of a solution is usually the solvent. The material other than the solvent is the solute. We say that we dissolve the solute into the solvent. Some solutions are so common to us that we give them a unique name. A solution of water and sugar is called syrup. A solution of sodium chloride (common table salt) in water is called brine

Chapter I Problem and its Background A. Introduction Chelating agent is a compound that combines with metal ions to form stable ring structures. It is used to reduce the concentration of free metal ion in solution by complexing it. From the Greek term “chela” that means “the great claw” of the lobster or other crustaceans‚ chelate‚ root word for “chelating”‚ suggests the way in which an organic compound “clamps” onto the cationic element‚ which it chelates. In order for a compound to be

oblivious that their city was going to become the origin of concentration camps and of the Holocaust‚ the mass murder committed by the Nazi s in World War II. Dachau Concentration Camp‚ which would soon be placed on the edge of their community‚ would serve as a model for all Nazi extermination camps. This perfect prototype of a Nazi killing machine has come to represent the start of the horror-filled Holocaust and the Nazi’s determination to achieve a perfect society during World War II. On March
