... b. If a compound contains 300 kJ of energy and it breaks up into two elements each containing 160 kJ, then the reaction should have released 20 kJ of heat into the environment. FALSE (160 + 160) – 300 = + 20 kJ = endothermic, so it needs to absorb or steal 20 kJ from its environment, not release. ...
