Calorimetry To determine the specific heat of a metal and its approximate atomic mass. To determine the heat of neutralization for a strong acid-strong base reaction. To determine the quantity and direction of heat flow for the dissolution of salt. Post Lab Questions and Answers: 1. In parts A and B in‚ the calorimeter‚ although a good insulator‚ absorbs some heat when the system is above room temperature. Is the reported value for the specific heat of the metal too high or too low? Explain

calorimeter was standardized using benzoic acid and the average heat capacity of the bomb calorimeter was calculated to be 10.60.3205 kJ/K. From that‚ the These results show that heats of combustions of unknown substances can be determined via bomb calorimetry. Introduction The first law of thermodynamics states that energy is conserved.2 Using that law it can be said that the change in the internal energy of a system () depends on the heat added (q) to the system and the work (w) done by the system

How to write an annotation (http://legacy.earlham.edu/library/content/resources/writing/annotations.html) An annotation is a brief summary of a book‚ article‚ or other publication. An abstract is also a summary‚ but there is a difference between the two. An abstract is simply a summary of a work‚ whereas the purpose of an annotation is to describe the work in such a way that the reader can decide whether or not to read the work itself. The following points provide guidance for writing annotations

Multiplication of contaminant bacteria in urine and interpretation of delayed culture. Abstract A prospective study of the bacterial populations of non-infected urine was mounted in an attempt to define the length of delay between voiding and analysis during which culture would not give false positive results due to the multiplication of contaminant bacteria present at the time of voiding. The findings suggest that culture of urine within four hours of voiding is likely to give a true indication

Abstract The exploratory research in this thesis analyses the influence of culture and politics on accounting change since independence. A theoretical framework is proposed within which historical studies of the influence of culture and politics on accounting and accounting change may be undertaken. In this framework‚ the accounting system is viewed as part of the whole social system in the country of study‚ providing information for decision making and providing a tool for economic

Character Education at Schools in Indonesia* Abstract One of the main arguments of curriculum renewal in Indonesia‚ focusing more on character building and integrated learning‚ is the escalating demand of curriculum adaptation to social phenomenon happening in the society‚ in this case juvenile delinquency (Kemendiknas‚ 2013). Curriculum 2006‚ known as KTSP‚ was regarded‚ besides outdated and overloaded‚ unable to negotiate such a social complexity. There has also been a debate in the society
