energy transfer
1 in a reaction
2 can be taken in or given out as heat energy
3 combustion
3.1 exothermic reaction
3.1.1 heat is given out
3.1.2 exo
4 endothermic reaction
4.1 takes in heat
4.2 endo
5 temperature changes
5.1 helps decide if the reaction is exo or endo
6 energy & bonds
6.1 energy must be supplied to break bonds
6.2 energy is always released when bonds are formed
6.3 in reactions old bonds are broken and new bonds are formed
6.4 NaCL -ENERGY> Na + CL
6.4.1 endo
6.5 Mg + O -> MgO + ENERGY
6.5.1 exo
