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

Lab 2: Reaction Order and Rate Laws Khadijah Maraheel Location: My apartment September 27th-28th 2017 Course Number: Chem112 Abstract: The purpose of this lab is to find the rate law of the reactants and the reactions order. My beginning thought was I would find whole numbers but that would be to easy. My answers were all with decimals. I found that my rate law Is k (HCl)1.36 (Na2S2O3)0.84. I was expecting the solution to change color but I never thought it would turn

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

2/28/2013 Introduction: Hess ’s law is a terminology in chemistry named after Germain Hess‚ a Swiss-born Russian chemist and physician who published it in 1840. The law states that the total enthalpy change during the complete course of a reaction is the same whether the reaction is made in one step or in several steps. Enthalpy cannot be directly measured‚ but rather the change in enthalpy. Enthalpy is described as the change in kinetic and thermal energy. Hess’s law states that the enthalpy change

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

Experimental Determination of the Electrostatic Force acting between two charged pith balls Equipment: a pvc pipe and fur or wool‚ a metric ruler‚ a protractor‚ two pith balls on a stand as in figure 1. Your teacher will tell you the mass of your pith balls. Procedure: Make sure the strings of your two pith balls are untangled as in figure 1. Make sure that the pith balls are neutral by rubbing

2014 Empirical Analysis of Mendel’s Laws Objective: To determine if Mendel’s law of segregation and independent assortment genetic principle’s hold true by observing the genotypes of both the F1 and F2 generation of Drosophilia Melanogaster flies and applying the Chi Square analysis to the F2 offspring to see if the our results fall inside or outside statistical variation. Methods: This experiment was carried out over a five-week process. Each lab bench crossed two parental generations:
