Chapter 5, Problem 16Q

(a)

Interpretation Introduction

Interpretation:

The balanced chemical equation has to be written for the combustion of ethane (C2H6).

Concept introduction:

Balancing reaction:

Balanced reaction is a chemical reaction in which number of atoms for each element in the reaction and the total charge are same on both reactant side and the product side.

Steps in balancing the information

  • Step 1: Write the unbalanced equation
  • Step 2: Find the coefficient to balance the equation.
  • The coefficient should be reduced to the smallest whole number.

(b)

Interpretation Introduction

Interpretation:

The Lewis structure has to written for the combustion of ethane reaction.

Concept introduction:

Electron-dot (Lewis) symbol: The numbers of valence electron are shown using dot symbol around the atomic symbol.

The valance electrons are represented as a dot; the dots are distributed around the four sides of the element symbol. Primarily, fill electrons in each side of the atomic symbol, if the element has five or more than five electrons, the electrons are added in the four sides of the element symbol then it will get paired. The maximum dot of the electron in one side of the element symbol is two.

(b)

Interpretation Introduction

Interpretation:

Heat is produced has to be calculated when 1.0 mol of ethane undergoes complete combustion reaction.
