Calorimetry and Specific Heat Tessa Williams Chemistry 111 11/13/13 Abstract: In this experiment‚ the specific heat and the density of an unknown metal was determined in order to identify the unknown metal. The average specific heat of the unknown metal was 0.197˚C and was determined using a calorimeter. The density of the unknown metal was 6.57 g/mL and was determined using a cylinder and displacement. Using the specific heat value of the unknown metal and its density‚ it

In part A of the experiment the two values obtained for the specific heat capacity of the metal were about .0500 J/mol. This is a large deviation‚ with both of these values identifying very different metals. The average heat capacity identified the metal used as brass. The average heat capacity calculated was .3776 J/mol and the actual heat capacity of brass is .375 J/mol. The second run displayed the closest value to the actual value. A source of error that may have caused a large divide in the

The Benefits Derived From a Low Student –Teacher Ratio Albert Fuller American Intercontinental University English Composition II What are the possibilities and impacts of a low student-teacher ratio and how can it be beneficial to both students and teachers alike. Imagine yourself in a class of 30 or more students‚ you are eager to learn but find it hard to grab the attention of the teacher. You feel lost in a class of pupils and you don’t know if you are going to absorb the

Heat of Neutralization for an acid-base reaction Contents: - Abstract - Introduction - Results and Discussions - Conclusion - References Abstract: In the experimental procedure we will measure the heat of neutralization when an acid and base react to form 1 mole of water. This quantity of heat is measured experimentally by allowing the reaction to take place in a thermally insulated Styrofoam cup calorimeter. The heat liberated in the neutralization reaction will

Heat Treatment and Qualitative Metallographic Analysis Lab ME 3228: Mechanics & Materials Laboratory Summary Comparing a material’s initial treatment and the microstructures that are formed from different processes‚ an engineer can accurately understand why certain treated materials of the same family can be stronger than another. In this experiment annealed and cold-worked specimens of AISI 1018 STEEL are used‚ along with a Hardness tester‚ a grinding and polishing process‚ and a micrograph

Describe the major migrations into the Caribbean that greatly impacted society and culture. Migration is the movement of people from one place to another‚ but in this case‚ it is the movement of a group of people from another country coming into the Caribbean for better opportunities mainly‚ because of slavery. The major migrations into the Caribbean were mainly slavery‚ indentureship‚ encomienda and the plantation system. All these were the impacts of the historical processes. Influences of the
