heat energy released when we eat snack foods such as popcorn or potato chips. This lab includes three burning tests of different foods with different energy contents. Calorimetry is the science associated with determining the changes in energy of a system by measuring the heat exchanged with the surroundings(Calorimeters and Calorimetry). It requires us to create a soda can calorimeter which is a soda can with water inside in order to absorb heat energy and determine the temperature changes of water

Introduction The ability to identify metals is an extremely important one. With this ability‚ we can correctly assign different traits‚ and use the metal in its most suitable environment. This is important to many industries‚ where metals play an increasingly large role. Determining the identity of the metal is paramount to determining what conditions to use the metal under. This seemly simple task is‚ however‚ can be quite complex‚ as there are many ways by which one can identify a metal

Molarity of these samples was also calculated to determine concentration and percent error rate. Students also analyzed the concentration of blue dye #1 to determine the concentration of blue dye #1 in a commercial blue dye drink

December 5‚ 2011 Kylie Case‚ Emma McKee‚ Rebecca Smith Purpose: In this lab‚ the purpose was to verify Hess’s Law. Theory: Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The first being enthalpy of reaction‚ ΔHrxn‚ which is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant pressure in the reaction. The change represents the difference

Miguel Paulo D. Valdez BS Chem-3 EXPERIMENT 14- Heat Effects and Calorimetry Objective/ Introduction: Heat is a form of energy‚ sometimes called thermal energy‚ which can pass spontaneously from an object at a high temperature to an object at a lower temperature. If the two objects are in contact‚ they will‚ given sufficient time‚ both reach the same temperature. Heat always travels from hot to cold objects and two objects will reach an equilibrium temperature. Heat flow is commonly measured
