Calorimetry is the measurement of heat transfer. Devices that measure the amount of heat released or absorbed during a process are called calorimeters. A Coffee cup calorimeter is the simplest calorimeter and is often used to measure the heats of chemical reactions at constant pressure (also called enthalpies). This calorimeter consists of a Styrofoam cup with a plastic lid and a thermometer. in today's workshop, we will use calorimetry to calculate the standard molar enthalpy of reaction or the enthalpy change that occurs in a system when 1 mole of matter is transformed by a chemical reaction at 1 atm: _Delta H = q_rxn (in J/mole, at constant P and p V-work only), where q = cm Delta T A student wants to measure the heat of neutralization reaction. To do this she mixed in a coffer cup calorimeter 35.0 mL of 0.70M HCI solution and 65.0 mL of 0.50M NaOH solution both at 22.0 degree C initially. She then continued to measure the temperature of the mixture for 10 minutes. Write a chemical equation, a complete ionic and a net ionic equation for this reaction.
