Objective: The purpose of this lab is to demonstrate that there is a linear relationship between the number of molecules that can absorb light present in a solution and the amount of light absorbed by a solution. This lab should prove that Beer’s law and the equation A=a x b x c‚ is a linear relationship. Procedure: The only deviations in the lab procedure was that the stock solution was made before arrival to the lab with 0.570 g of KMnO4 in 0.500 L. The diluted solutions and the

Hess’s Law and the Molar Enthalpy of Combustion for Magnesium Purpose: The purpose of the lab ultimately is to find the molar enthalpy of magnesium. This is done by finding the enthalpy changes of reactions (2) and (3). The enthalpy changes of reactions (2) and (3) along with the enthalpy change given for reaction (4) can be used to arrive at a value of the molar enthalpy of combustion of magnesium by using Hess’s Law. Hypothesis: By using Hess’s law to calculate the molar enthalpy of combustion

Gas Laws Lab Introduction: The four basic physical properties of a gas sample are pressure‚ volume‚ temperature‚ and number of moles. The volume simply indicates the volume of the container since a gas will take up all space available to it. The temperature indicates the average kinetic energy of the gas particles. For gases‚ the temperature must be converted to the Kelvin unit. The pressure of the gas indicates the number of collisions with each other and the wall of the container. The number

PHYS113 Lab1: Coulomb’s Law ABSTRACT Performing this experimentation will allow one to investigate the relationship quantitative relationship between the electrostatic force and the distance between charged objects. First a simply observation was made of the electrical forces on two pieces of tape taking note of their attraction and repulsion. This same phenomenon was observed in the experimentation of two charged spheres. Furthermore the we used this experimentation to determine the

Taha Al-Yousif Hooke’s Law Lab Date conducted: September 18th 2013 Partners: Mohammed‚ Liam‚ Ben Nguyen Purpose: The purpose of this experiment is to find the relationship between the stretch of the spring and the attached mass and to verify that this relationship is accurately described by Hook’s Law. Theory: Hooke’s Law states that to extend a spring by an amount (Stretch) from its previous position‚ one needs to add an external force (Mass). Therefore

Introduction The purpose of this experiment was to determine the rate law graphically from the rate of disappearance and the x y values also the specific rate constant (k). Activation energy was also determined‚ and the effect of catalyst was evaluated in the reaction between peroxodisulphate ion S2O82-‚ and iodide ion‚ I-. S2O82-(aq) + 3 I-(aq) --> 2 SO42-(aq) + I3(aq) The general expression for the rate law‚ given this overall reaction‚ is: rate of disappearance of S2O82- = k[S2O82-]m[I-]n

Rick Hess was diagnosed with diabetes in his early 40s. When he was in medical school‚ he participated in a study that analyzed insulin. His results were low and a little out of the normal levels. However‚ if he would have known more about the results like they do now‚ it would have predicted he would have become diabetic. In addition to being a diabetic‚ Rick has also had to overcome cerebrovascular disease in his 70s. Rick Hess is now 76 years old. He attended the West Virginia University to
