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

Please answer part c and b part a is done Part A) Consider the structural changes that occur in the following molecules. Begin by drawing the best Lewis Structure for each of the following molecules. BH3 CH4 NH3 H2O HF Part B)What are the ideal bond angles for each structure, and which are expected to be distorted? For the ones that are distorted look up on the internet and record their experimental values here: Part C)According to Lewis and VSEPR theory, why do these changes occur?

Determine the structures of the molecules described in the following problems. Also note, in the combustion of N containing compounds, N2(g) is made. Using your understanding of bond enthalpies, predict the enthalpy change associated with the conversion of the amino acid lysine to cadaverine (and any other by-products of the reaction). You will need to have a balanced chemical reaction to do this. Assume that the reaction occurs in the gas phase.

Consider the incomplete structure. Add formal charges as necessary to the structure. All unshared valence electrons are shown. Do not alter the structure‑just add charges. If you need to revert the drawing palette to the original state, select the More menu, then select Reset Drawing.
