Energetics

I learn on how to use the energy cycle in finding out the various enthalpy changes in a balanced equation. However i m still a little unsure about it. It is really new for me n so i m getting use to it.

The enegry level diagram/ Born Haber Cycle is somthing interesting . At first it was diffcult, after my chemistry teacher explained and went throught a few examples on how to draw the diagram i know how to do it. All the postive enthalpy changes which is the endothermic reaction all point upwards while all the negative enthalpy changes which is the exothermic reaction all point downwards
