. Due to the fact that alcohol is found in excess in this reaction it can be removed from the expression‚ leaving the expression: Beers Law states that the amount of light absorbed is proportional to the concentration of a species‚ in this case (3). Where A is the measure of absorbance. Ԑ is the molar absorptivity‚ and is the constant of proportionality. And c is the concentration of the absorbing species‚ . When this information is graphed with absorbance on the y axis and at different points

Experiment: Observations of Chemical and Physical Changes Derrick Davis Lab partner: None Location: My house Date Performed 25 Feb 15; 1600 CHE111-CO2 Photo 1 (Photo of me properly wearing safety goggles holding the student information card) Abstract: In chemistry it is important to understand the difference between physical and chemical changes. The objective of this experiment was to perform tests using heat or chemical mediators and observe the results for any physical or chemical changes

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

Biology 5/14/15 Title: Classification of Species Purpose: The purpose of this lab is to understand the concept of taxonomic classification and to practice using dichotomous keys for classification. Procedure: To start the experiment with exercise 1‚ I gathered all of the needed supplies‚ both from around my house and from the lab paq CD. I then began exercise one by printing the images in Figure 5 from my labpaq. I then proceeded to cut out each shark. Next I carefully examined the drawing of
