For my chemistry coursework we are looking at exothermic and endothermic reactions but i dont get what they mean, can someone please explain them to me?

Exothermic releases heat/energy into its surroundings whilst endothermic absorbs heat/energy from its surroundings

Exothermic - the reaction releases heat
Endothermic - the reaction absorbs heat
Exothermic - the reaction releases heat
Endothermic - the reaction absorbs heat

- Bond Formation (new bonds made)
- Releases energy (in the form of heat) to the surroundings
- Resulting in a rise in temperature
Endothermic:
- Bond breaking (Existing bonds broken)
- Takes in energy (heat) from the surroundings
- Resulting in a fall in temperature

Basically, when bonds break, it takes energy. Conversely, when bonds form, it releases energy. So the difference between Exothermic and Endothermic reactions is that in Exos, the bond-forming releases more energy than the bond-breaking uses up, which means that overall, the reaction releases energy. The opposite is true for Endos. You can usually tell if a reaction is Exo or Endothermic by if it consists of burning, oxidising, or reacting an acid with a metal (Exothermic) vs if it involves carbonates, etc. (Endothermic). Hope this is helpful
