Hess’s Law and the Molar Enthalpy of Combustion for Magnesium Purpose: The purpose of the lab ultimately is to find the molar enthalpy of magnesium. This is done by finding the enthalpy changes of reactions (2) and (3). The enthalpy changes of reactions (2) and (3) along with the enthalpy change given for reaction (4) can be used to arrive at a value of the molar enthalpy of combustion of magnesium by using Hess’s Law. Hypothesis: By using Hess’s law to calculate the molar enthalpy of combustion

MY REACTION PAPER (MEET JOE BLACK) As I have watched the movie entitled “Meet Joe Black”‚ I was surprised by the flow of the story. The story is all about Bill (Anthony Hopkins)‚ a multimillionaire who run a successful empire for the past forty years in New York. But‚ after his wife passes away he feels empty and becomes convinced that Death is now after him too. He hears strange voices in his head‚ mimicking his own words‚ but they are phony and ridicule him in every possible manner. Comparing

Reaction Time Reaserch Question: To design on investigation into stimuli ( sight/sound ) that may affect reaction time ( time taken for a response to occur in reaction to a stimulus.) Background information: Humans perceive their outside world through five senses: touch ‚sight‚ taste‚ smell and sound. The reason why we have the 5 major senses is to detect and discriminate among the signals that comes from our environment. These signals carry information necessary for us to support our vital

A REACTION PAPER demonstrates comprehension of the assigned readings and contain a critical and thoughtful reaction to the reading. Reaction should make up the majority of the Reaction Paper. Make sure that your paper is in the form of an essay with an introduction‚ body and conclusion. a) Focus on an aspect of the reading that you will argue pertains to some issue or idea’ “Does the reading support‚ undermine or come into tension with previous issues or concepts?” Explain why it is significant

a chemical reaction will occur spontaneously or non-spontaneously is an important aspect of thermodynamics. Spontaneity is determined from free energy‚ or Gibbs free energy. The equation (1) gives the relationship of how entropy (∆S) and enthalpy (∆H) along with temperature affects the amount of free energy‚ and henceforth the spontaneity. A spontaneous process may be quick or slow‚ and it is only affected by temperature and energy‚ therefore it is not related to kinetics or reaction rate. equation
