Hess’s Law Mengyuan Wu (Millie) 7 January‚ 14 Aim: The purpose of this experiment is to determine the enthalpy change for the reaction: Introduction: It is impossible to measure the enthalpy change for this reaction directly because the process cannot be controlled. However‚ you can calculate this enthalpy change by using the Hess’s Law. Pre- lab Calculations: Calculation 1: Required Masses for Reaction The ratio of and is required to be 1:100 for Table 1: Calculation

1st Entry: Introduction From the title of this book‚ I could infer that the book will be about how the elements were discovered‚ the origin of their names and the people who discovered each element that is now a part of the periodic table. The author of the book‚ Hugh Aldersey-Williams‚ must be an individual of great knowledge and has a deep interest and understanding of chemistry—or else he would have never wrote this book. In this book‚ I expect that I would be able to learn how the ancients

Due Date: March 12‚ 2013 Introduction Hooke’s law states that force is directly proportional to the displacement of the spring that has been stretched or compressed from the equilibrium position. The force that takes place is referred to as a restoring force because it acts on an object to return it to a state of equilibrium. This is Hooke’s Law. It can be shown as: F = -kx In the first formula ---> F is the force of weight k is the spring constant x is the displacement In this
