    calculate energy needed to break the bonds - energy released when bonds formed . the most negative asnwer on the right side and most positive to the left side. example: in P: Br-Br is brocken and no bond is made so 193-0=+193 in Q: no bonds are broken only bond make is Cl-Cl so 0-244=- 244 in...
