Chapter 3: Thermochemistry
What you need to learn in this chapter
In this chapter, we will be learning about Thermochemistry. We will start by understanding energy changes in chemical reactions. Through activities, we will be able to deduce whether a reaction is exothermic or endothermic. We will also learn how to interpret energy level diagrams.
Next, we will study heat of reaction. Through activities, we will determine the heat of precipitation and heat of displacement.
Lastly, we will explore the application of exothermic and endothermic reactions in daily life. We will discuss examples of these reactions and analyze fuel value.
By the end of this chapter, we will have a better understanding of energy changes in chemical reactions and how they apply to our everyday lives.
