The copper sulfate pentahydrate ’s appearance first observing are contaminated‚ white coat outside blue crystals. Prelab question: 1. Explain briefly why CuSO4 is more soluble in water than in an organic (nonpolar)

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:

1. OBJECTIVES (a) To determine the equivalent circuit parameters of a 3-phase squirrel-cage induction motor from laboratory test data. (b) To determine the performance characteristics of an induction motor under load conditions. (c) To control the no-load speed of an induction motor. 2. INTRODUCTION 2.1 Three-phase squirrel-cage induction motors An induction motor is a transformer with a rotating secondary winding. It has two essential components: an outer stationary stator and an

OLD COINS TURN TO GOLD DESIGN: Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon. Procedure: First‚ we turned on the hot plate.

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

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

Job Safety Analysis or Job Hazard Analysis All employers have duty of care to individuals‚ staff‚ contractors or third parties in the workplace. It is also a legal requirement that organizations should document any health and safety risks that have been identified in the workplace. Equally‚ it is necessary to record the actions taken to reduce those risks What is a Job Safety Analysis or Job Hazard Analysis? One way to increase the knowledge of hazards in the workplace is to conduct

called a spectrophotometer detects the amount of light that passes through the sample and the percent transmittance can be recorded from the meter. In the lab‚ multiple homogeneous solutions are made. There was not a way to determine the differences in concentrations‚ but the Spec 20 made it possible to measure the difference. The Beer-Lambert Law is a graph used to record
