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

Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

This report will cover chapters 9-16 of Catcher in the Rye by J. D Salinger. Holden has traveled to New York City and is unsure what to do now that he has left the preparatory school‚ that he was previously attending. Throughout these chapters Holden travels around New York‚ during this time he runs into some unique people‚ some that he knows and some strangers. Has some interesting experiences‚ some that end up not going well for him. I hope that he learns from his experiences that he has had. One

Introduction (40%) Background Provide a focused review of literature relevant to proposal and any theoretical model that you would like to propose. Example: “Smith (19XX) reviewed literature on spacing of training and found that spacing study trials improved long-term retention…” Hypothesis Based on literature and own ideas‚ state the objective of the experiment and describe the results that you expect to obtain? Example: “The objective of the present proposal is to test the notion that spacing

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by
