Cindy Rodriguez Professor. Mascarano Biology Lab Fall 2014 Determining the properties of an enzyme Abstract: To determine the properties of an enzyme, a peroxidase, turnip extract is used in this experiment Enzymes are large proteins that are responsible for the speed at which chemical reactions they are involved in taking place. Enzymes speed up chemical reactions by lowering the activation energy of a reaction, the amount of energy necessary to trigger a

. Introduction: A civil engineer should know how to use theodolite to measure width or height of building or something else . In the last surveying lab we used the theodolite instrument and we use it for measuring the angles vertical and horizontal that the civil engineer could need to do some subjects and its simple and easy to use Method: During this experiment we’ll locate 2 points and measure the distance between them and then we’ll but the theodolite on each point and measure the

Dr. Hjorth-Gustin Chemistry 201 Lab November 8th, 2010 Synthesis and Analysis of Iron(III) Oxalate Complex Discussion This experiment initially involved the synthesis of an iron (III) oxalate complex with the general formula Kw[Fex(C2O4)y] zH2O. The variables x, y, and z were determined through the duration of the entire experiment. Part 1 involves the synthesis of an iron (III) oxalate complex. The iron is first presented in its Fe2+ form, so it must first be oxidized to Fe3+

The objective of this lab is to conduct a titration of a sample of bleach with thiosulfate and to determine its end point using a starch indicator. The oxidizing capacity of the bleach will also be derived by determining the percentage by mass of the bleach that is sodium hypochlorite. The overall chemical reaction equation will be created by balancing the two redox reactions. Most bleaches contain the oxidizing agent- the hypochlorite ion. This ion typically comes in the form of a calcium salt

Intro Networking Lab 3 3.1.1 It would be very hard for all devices to communicate with each other. Everyone would have to buy the same brand for the devices to communicate. This would be horrible for businesses and people. Everyone would have to buy the same brand. That would make sure that they can all talk to each other. Businesses would not be able to talk to other departments. Things would not run smoothly. 3.1.2 The OSI model breaks down all the layers. And describes the layers and what

Each time you open a port or allow a program to communicate through a firewall, your computer becomes a bit less secure. The more allowed programs or open ports your firewall has, the more opportunities there are for hackers or malicious software to use one of those openings to spread a worm, access your files, or use your computer to spread malicious
