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 chemical reaction . They release heat because the reactant molecules require less heat for breakage of bonds than the product molecules. Endothermic reaction: Endothermic reactions are those in which heat is absorbed during any chemical reaction. In such type of reactions, external energy is needed

Interpretation Introduction

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 chemical reaction. They release heat because the reactant molecules require less heat for breakage of bonds than the product molecules.

Endothermic reaction: Endothermic reactions are those in which heat is absorbed during any chemical reaction. In such type of reactions, external energy is needed
