Interpretation:
Using the given bond energy values check whether the hydrogen really a good fuel or not and also check the calculated value of hydrogen matches to the given equation or not.
Concept Introduction:
Energy of Combustion: The energy released in the form of heat when given substance undergoes combustion reaction.
A Fuel is a substance that releases energy when it gets burnt in presence of Oxygen. The phenomenon a substance getting burnt in presence of Oxygen is termed as combustion and it is exothermic process. The larger the amount of heat released per gram of a substance, greater the potential it has to be a fuel.
Exothermic reaction: Exothermic reactions are those in which evolution of heat takes place during any
Endothermic reaction: Endothermic reactions are those in which heat is absorbed during any chemical reaction. In such type of reactions, external energy is needed
