Calorimetry Experiment Purpose: The objective of this lab is to determine the enthalpy change for NaOH(aq) + HCl(aq) NaCl (aq) + H2O(l) Procedure: Before measuring the enthalpy of acid base neutralization‚ my partner Brian and I determined a calorimeter constant‚ using a homemade polystyrene calorimeter. With the following formula and data: qhot= cm (Tf-Ti) qcold=cm(Tf-Ti) SYSTEM DATA SURROUNDINGS DATA Water cold Mass: 50mL Water hot Mass: 50mL C=4.18 C=4.18 Ti=20 C Ti=31

investigated and what variations of the reactions would be studied. The two requirements that were kept in mind while creating the calorimeter were that it should be a good insulator‚ meaning that it does not allow for the transfer of heat between two systems in an environment‚ and that it should have the lowest heat capacity possible (ideally 0C) so that the calorimeter absorbs as little of the heat energy produced as possible. The calorimeters produced by the experimenters were constructed

MANAGEMENT’ AN IMPORTANT METRIC By: Masoud. Noordeh (DBA student) Abstract In today’s dynamic business environment‚ Knowledge management systems facilitate organizational learning and knowledge creation. They are designed to provide rapid feedback to knowledge workers and significantly improve business performance. This paper examines the concept of knowledge management metric from the view point of Paul Strassmann. Keywords: Knowledge‚ Performance Management Metric‚ Knowledge Management. Introduction

The milgram experiment. The three people involved were: the one running the experiment‚ the subject of the experiment a volunteer‚ and a person pretending to be a volunteer. These three persons fill three distinct roles: the Experimenter an authoritative role‚ the Teacher a role intended to obey the orders of the Experimenter‚ and the Learner the recipient of stimulus from the Teacher. The subject and the actor both drew slips of paper to determine their roles‚ but unknown to the subject‚ both slips

community as a whole is altered (Friedman 2017). To study succession‚ one must use one of the following methods: to observe any patterns that occur‚ to conduct experiments that manipulate specific variables in a community‚ or to construct a model that may undergo succession. One example of an experiment that measures microbial succession was an experiment observing changes in traditional Chinese soy sauce over time (Sulaiman et al. 2014). The fermentation of the soy sauce brine revealed that the primary bacteria

STARBUCKS CASE STUDY INTRODUCTION Starbucks was created in 1971 by 3 coffee fanatics in Seattle‚ and was originally an Arabica beans store. It started expanding to a coffee shop and opened more stores throughout the country in the 1990’s and today‚ Starbucks owns more than 15‚000 stores in 50 countries‚ and it had become the premier roaster and retailer of specialty coffee in the world. Starbucks’ mission statement is: “To inspire and nurture the human spirit – one person‚ one cup and one neighbourhood
