TITLE Crime and Dye Lab Special Projects 1 Martin Enem LAB SECTION: BB2 INTRODUCTION Light is usually viewed as a result of the heating of a substance. The higher the temperature at which the substance is heated‚ the greater the vibrations that lead to certain light intensity given off by the molecule. It is this same theory that suggests why steel glows red hot when heated to high enough temperatures. The process of light emissions can also be induces through other means. 1 One

chosen as the subject of a case study. A non-isothermal reactor operating at temperatures between 575 and 675 K and with feed compositions corresponding to industrial conditions was used. A method of sequential regression analysis was applied to determine the kinetic parameters from the temperature and conversion profiles of the bed. The experimental data could be fitted by a power-law type of reaction rate expression. The rate equation combined with a plug flow model of the bed was successfully used

Intermolecular forces – design lab Research question: To calculate the solubility of equal masses nitrates of four di-positive ions (Lead Nitrate‚ Barium Nitrate‚ Copper Nitrate & Ferrous Nitrate of 0.5 M concentration) in an equal volume of water and relate this to the ionic radius of the element and the molar mass of the nitrate chosen and hence comment on the intermolecular forces in each of these nitrates. + write mass Justification of the research question: I was particularly interested

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Tim Readmond AP Biology Lab Report I. Title a. Modeling Diffusion and Osmosis II. Introduction a. If one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose‚ the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic‚ which is why water moves from the bag to the beaker and the bag loses mass. b. The purpose of this experiment is to see whether

COMBUSTION OF MAGNESIUM OXIDE DESIGN Aim/Purpose: To calculate the number of moles and the empirical formula of magnesium oxide. Safety precautions: 1) Wear lab coat 2) Wear gogles. 3)Make sure the bunsen burner is working properly and their is no leakage. 4) Wear gloves. Hypothesis: The weight of the magnesium ribbon increases after burning‚ so this indicated that their was a change in mass. This change happened because of the magnesium ribbon inside the crucible which reacted with Oxygen

LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances

Pos t-Lab Data Summary Note : some questions will display a variable like "nCount" or "SyInput" instead of an actual number in the data summary. Q# Question Text 5) Data Entry - No Scoring Enter the precise mass in GRAMS of the potassium iodate used to prepare your primary standard solution. Your mass precision should be reported to a thousandth of a gram‚ i.e. 0.302. (Use 3 significant figures.) Your Answer: 0.536 No Points Possible 6) Scoring Scheme: 3-3-2-1 If one had weighed out precisely

This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test
