Objective(s):

At the end of this lesson, students should be able to :

1. Determine the heat capacity of a calorimeter

2. Determine the heat of neutralization of HCl & NaOH
   

Open Ended

What is thermochemistry?

Open Ended

Name a device/ instrument used to measure the enthalpy of reaction, ΔH_reaction and state it's purpose

Multiple Select

Which of the following represent the other term of Enthalpy of a reaction?

• temperature change of reaction

• Enthalpy change

• Heat content of reaction

• Heat of reaction

Draw

Write the Thermochemical equation of neutralization between HCl & NaOH

Open Ended

The specific heat capacity, c of copper metal is 0.385 J g⁻¹ °C⁻¹ while the heat capacity, C of a calorimeter is 20.0 J °C⁻¹. Explain.

Open Ended

Why must the same calorimeter be used for both parts of experiment?
