Journal Entry:
In an endothermic reaction, is more energy required for
breaking bonds or given off by forming new bonds?
Learning Intentions
- We will learn how to explain the source of heat in a
combustion reaction.
- We will learn how to calculate the net energy exchange
due to a chemical reaction
- We will learn how to draw and interpret energy diagrams
- We will learn how to define activation energy and be able
to identify it on a energy diagram.
Closing Task:
You can draw and
interpret energy diagrams.
Content Standards being covered in this unit:
Students can develop a model to illustrate that the release or absorption of
energy from a chemical reaction system depends upon the changes in total bond
energy.(HS-PS1-4 and CCC Energy and Matter) .
