By measuring the reaction rate between bleach and the dye‚ the order of the reaction was determined to be first order. Introduction The study of kinetics is important for studying the amount of time it takes for a particular reaction to reach

Unknown Lab Report #1 Unknown #1 April 25‚ 2012 Microbiology Spring 2012 MCB2010C Unknown #1 Introduction Identity of a microorganism has proven to be very significant. Doing so can help identify diseases and created treatment and cures for such diseases. As a result‚ various laboratory tests were performed to an unknown microbe (Unknown #1) found in the water of a nearby pond. By identify the microbe‚ the safety of the water will be known to those around it. Materials and Methods

Experiment-5 Thermal physics is the combined study of thermodynamics‚ statistical mechanics‚ and kinetic theory. This practical is done to measure the temperature drop of water over a period of time (30 minutes). Research question- What is the rate of temperature change over a period of 30 minutes? Independent variable- time Dependent variable- the temperature of water Controlled variables- the amount of water in the calorimeter - The stop watch

9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚

Results Experiment I: As a general trend O2 production and reaction velocity increased with increasing catalase concentration‚ however‚ the 33% percent catalase concentration showed a drop of 0.175 mL O2/s compared to the 25% catalase concentration (figure 1.2). The velocity of 25% catalase was 0.275 mL/s‚ 33% was 0.1 mL/s‚ 50% was 0.435 mL/s‚ and 75% catalase was 0.575 mL/s (figure 1.1). The 50% catalase concentration produced the most O2 overall however the 75% catalase concentration had the fastest

Lab Report Diffusion is - One of two kinds of passive transport‚ - Diffusion can transport ions from higher concentration to lower concentration region without any other forces. - A net movement of molecules in and out of cell membrane - Diffusion can be affected by the steepness of the concentration gradient. Lab question: Is the rate of diffusion influenced by the presence of second molecule? Prediction: the rate of diffusion is influenced by the presence of second molecule

Maryely Ramirez Professor Theresa Sterner Bio Lab 105 04 November 2013 The Effects Environmental Temperature and pH have on the Activity of Porcine Pancreatic Amylase Introduction There are many types of enzymes and each has a specific job. Enzymes are particular types of proteins that help to speed up some reactions‚ such as reactants going to products. One of them is the amylase enzyme. Amylases are found in saliva‚ and pancreatic secretions of the small intestine. The function of amylase is

Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &

during the lab session Procedure Part A This lab was performed by the group members as they closed both low and high flow rotameters (Fig-2) and filled the tank with water. Then‚ the large rotameter was opened when the water in the tank had reached the internal baffle‚ so the flow from the tank was reduced by doing so. One member was in charge of adjusting the level of the water so it was always maintained over the baffle’s level during the lab (Fig-1). The first part of the lab was done
