Chem 105 Guide to the Formal Laboratory Report The purpose of a formal report is to communicate effectively to another person the goal‚ procedure‚ data analysis method‚ and results of your laboratory work. The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work

Introduction The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel‚ which leaves a clean test tube. Incomplete combustion

Material testing I. Topic: Tension testing 2.What is tension test? Tension test is a fundamental material science test in which a sample is subjected to uniaxial tension until failure. The results from the test are commonly used to select a material for an application‚ for quality control‚ and to predict how a material will react under other types of forces. Properties that are directly measured via a tensile test are ultimate tensile strength‚ maximum elongation and reduction in area. From

Laboratory Report The Plasma Membrane I. Introduction The Plasma membrane is the edge of life‚ the boundary that separates the cell from its surroundings. It controls the traffic of materials in and out of the cell. (Reece‚ 2011). It is incredibly thin that is very vital in maintaining the integrity of the cell. Not only does the plasma membrane bind the other organelles‚ it also forms a dynamic structure which gives them their remarkable activity and selectivity. (Hickman‚ 2008). Diffusion

Lab Report The Effect of Resting on Clothespin Squeezing. Hypothesis: If you rest then the clothespin squeezing rate will increase. Materials:- Clothespin Clock Sneakers Procedure: Separate class into two groups (exercisers and resters). Exercisers will do jumping jacks for a minute. Exercisers and registers will squeeze clothespin for a minute Repeat steps two and three. Total of three trails. Precaution: Shoes must be tied. Space between exercisers. Healthy exercisers

plane truss is first constructed. On installation of a surplus bar the truss becomes overdeterminate. By way of a load application device‚ straight or inclined forces are applied to the truss‚ thereby simulating various load cases. The occurring tensile and compressive forces in the bars are recorded by means of strain gauges. Computerised evaluation is provided by measurement amplifier FL 151. The software is used to manage the measurement data and provide graphical representation of the bar forces
