Energetics Practical 2: To Determine the Enthalpy Change of a Reaction Background Calcium Carbonate‚ CaCO₃‚ decomposes with heat to form CaO and CO₂. The objective of this practical was to determine the enthalpy change for this reaction by using an indirect method based upon the foundation of Hess’ Law. Both calcium oxide and calcium carbonate react readily with 2 mol/dm3. The reaction can be demonstrated as so: CaCO₃ (s) -> CaO(s) + CO₂ (g) Results: Raw Data Calcium Carbonate Mass of CaCO₃

Have you ever read an instruction manual on how to climb a staircase? This may seem absurd as climbing a staircase is such a common event that we take for granted. But Julio Cortazar has written ‘Instruction on How to Climb a Staircase’ and ‘Instructions on How to Wind a Watch’ to present us with a new way of looking at the intricacies of everyday life. The excerpt from ‘The Instruction Manual’ by Julio Cortazar can be read from many different perspectives. First‚ we can read it as a reminder of

Ever since the standardized test was first introduced‚ it began to suck out the creativity from school and forced all teachers to teach the same material to every students nationwide. It has long been theorized that no two minds are the same and if you ask parent with more than one children they will confirm it. So why teach the same thing to every student when even siblings don’t have the same mindset and learning patterns? President Obama said himself “Teachers should not be forced to spend the

Practical Ethics H.Narayanan‚ EE Department IIT Bombay‚ Mumbai (Text of a lecture delivered on 16th Oct 2012) A dilemma faced by young people‚ usually at the stage when they leave home for the first time‚ is that rules that they have lived by thus far seem questionable. On the one hand the impulses that tempt and torment them seem natural while on the other‚ breaking rules that the parents have taught them in their childhood seems very wrong. Further‚ those who break their shackles are in danger

Standardized work Kevin Clement | 10/27/15 | AE 570 Overview Standardized work is a lean concept that has been minimally used in the construction industry within the United States. However‚ it is one of the most powerful lean tools to apply in the construction industry. The goal of standardized work is to optimize productivity‚ safety and quality. The amount of detail that is put into developing a standardized work plan and directions is based on the type of project. If the project is very detailed

Standardized testing is the scourge that plagues the classroom and renders immobile the wheels of thought in a quagmire of ineffectual batteries of questions unintentionally fashioned to inaccurately assess a student ’s mastery of subject material. I intend to research the validity of standardized tests in school. The standardized tests can include the Stanford 9‚ PSAT‚ SAT‚ CRCT‚ etc. I chose this topic because I feel that educators and political leaders place an undue amount of importance on
