Finding the rate law was the overall goal of the laboratory. When finding the wavelength of the Azo Orange II dye‚ the highest wave was the point used‚ 483nm. The plotted points of the different concentrations absorbance’s made sense to have a steady upward slope because the dye was diluted in steady increments from full to ¾ and so on. Beer’s law was used next to calculate the absorbance of they time over time as bleach was added. One the absorbance value was calculated‚ the concentrations were

Note: Never use an acid- or vinegar-based descaling agent with 8% or more acetic acid to descale the appliance‚ as this may cause damage. http://www.diynot.com/forums/viewtopic

Aim: To determine a value for the spring’s force constant‚ k. Introduction: Hooke’s Law indicates the relationship between the amount of extension‚ e‚ of a spring to the size of the force‚ F‚ acing on it. This relationship may be written as :- F = ke F = ke where k is a constant for which particular spring you are using. It is the force constant of the spring. * The force applying on the spring‚ F‚ is denoted by Newton in SI Units. (N) * The amount of extension of the spring

Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often

The purpose of this lab was to learn about Newton’s laws of motion by completing an experiment‚ to see how the forces act on objects. The independent variable of this experiment is the type and amount of materials used for the interior of the vehicle (out of the material list) and how they were used. The dependent variable is how and if the interior of the vehicle protected the egg from getting cracked. The controlled variables of this experiment were the height that the vehicle was dropped from

Ideal Gas Law Lab 1. Procedure: First‚ we used a balance to weigh the canister of gas‚ and recorded that mass as the original weight. Then‚ we filled a large bucket with water and recorded the temperature. We then filled a small test tube with water at the same temperature and poured that water into a graduated cylinder to measure the original volume of water in the tube. We then poured the water back into the test tube and placed the tube into the bucket with the opening upwards‚ turning the

discovered that relationships between pressure‚ volume‚ and temperature were constant across types of gas. These early laws gave rise to the combined gas laws and the ideal gas laws. Charles’s Law Charles’ Law shows a direct relationship between the volume of a gas and the temperature of the gas. As with most things‚ as the temperature of a gas increases so does the volume. This law is shown as: Keep in mind that this scientific relationship only works for the same gas at two diverse temperatures
