    INTRODUCTION Given appropriate chemicals and equipment‚ the specific heat capacity and molar mass of a metal‚ enthalpy of neutralization of an acid and base‚ and the enthalpy of solution of an unknown salt can be determined by following specific procedures. All of these procedures require the use of a calorimeter‚ which are of two types: a bomb calorimeter and a coffee cup calorimeter. Calorimeters are simply devices used to measure the amount of heat gained or lost in a system. Although this

    Experiment 3: Enthalpy of Various Reactions Introduction A coffee cup calorimeter is an apparatus that is used to measure the quantity of thermal energy gained or lost in a chemical reaction. This experiment utilizes this apparatus‚ which is made from two styrofoam cups with plastic lids and a thermometer‚ to measure changes in thermal energy of various reactions. When using this type of apparatus‚ it is assumed that no heat is transferred between the calorimeter and the surroundings‚ and that

    Enthalpy of Neutralization J. Smith M. Smith CHEM 1290-xx 10-31-06 TA Purpose: The purpose of the experiment is to determine the calorimeter constant for the calorimeter holding a specific solution based on the data of heat lost and heat gained. The purpose is to also be able to determine the enthalpy of neutralization for the reaction of a strong acid (phosphoric acid) and a strong base (sodium hydroxide). Experimental: Materials: The materials needed for this lab included; 2 large beakers‚

    Experiment I: Thermochemistry Background: Thermochemistry is the branch of chemistry that focuses on the studies of chemical reactions or physical changes and heat associated with chemical reactions. According to the first law of thermodynamics‚ energy cannot be created or destroyed but it can be converted from one form into another and/or transferred between different atoms‚ molecules‚ or substances. In general‚ energy can be classified into two categories: kinetic and potential. Kinetic energy

    is put into water. There is an exchange of heat between the reaction mixture and the solvent‚ water. The heat flow associated with the reaction mixture is also equal to the enthalpy change. One of the simplest reactions that can be studied in solution occurs when a solid is dissolved in water. Same with the neutralization of HCl
