Confused about bond breaking and bond forming Chemistry AS

[fireman]

I forgot when it is exothermic and when it is endothermic?

bond breaking....endothermic..with a -ve sign
bond forming....exothermic...with a +ve sign

bond breaking....endothermic..with a -ve sign
bond forming....exothermic...with a +ve sign

signs are inversed! -ve for exothermic and +ve for endothermic!

During Bond Breaking process energy is required to break the existing bond ...therefore it is endothermic.
During bond breaking there is net release of energy when new bonds are formed...therefore it is exothermix.
