|
 | the idea of a chemical reaction; |
| the terms reactants, products, energy and covalent bond. |
After completing this unit, students should be able to:
| describe energy changes in bond formation and bond breaking; |
| explain energy diagrams representing endothermic and exothermic changes; |
| describe the differences between endothermic and exothermic reactions; |
| use a given equation and bond energy data to find the change in energy during a reaction; |
| qualitatively apply the idea of endothermic and exothermic reactions to experiments and everyday life situations; |
| successfully complete the revision quiz at the end of the unit; |
| explain each of the following words: activation energy, bond energy, chemical reaction, energy diagram, endothermic, exothermic, fuel, product, reactant. |
