| Exothermic Reactions give out heat energy to the surroundings RISE IN TEMPERATURE | Example - Burning Fuels |
| Endothermic Reaction takes in energy from surroundings FALL IN TEMPERATURE | Example - Thermal Decomposition |
| Adding an acid to an alkali is ... | Exothermic (Gives out heat energy) |
| Dissolving ammonium nitrate in water is ... | Endothermic (takes in heat energy) |
| Energy MUST be supplied to break bonds | Bond breaking is Endothermic (Takes in energy) |
| Energy is released when new bonds are formed | Bond Formation is Exothermic (Gives out energy) |
| Bond Breaking - Endothermic |
