(a)

Interpretation Introduction

Interpretation:

The product formed in combustion reaction of ethane ${\text{(CH}}_{\text{3}}{\text{CH}}_{\text{3}}\text{)}$ in presence of flame has to be explained.

Concept Introduction:

Hydrocarbon combustion reaction:

The hydrocarbon compound reacts with oxygen to form carbon dioxide and water as product is known as hydrocarbon combustion reaction.  It is an exothermic reaction.  The hydrocarbon compounds are generally organic compounds contain carbon and hydrogen element.  The compounds such as alkanes, alkenes, alkynes and aromatic compounds.

The general equation is given as,

  ${\text{C}}_{\text{x}}{\text{H}}_{\text{y}}{\text{+N(O}}_{\text{2}}\text{)}\leftrightarrow {\text{x(CO}}_{\text{2}}\text{)+}\frac{\text{y}}{\text{2}}{\text{(H}}_{\text{2}}\text{O)}$

Where,

• x represents the number of carbon atoms present in the hydrocarbon
• y represents the number of carbon atoms present in the hydrocarbon
• N represents the number of oxygen atoms requires in the hydrocarbon combustion reaction

(b)

Interpretation Introduction

Interpretation

The balanced equation for incomplete combustion of ethane ${\text{(CH}}_{\text{3}}{\text{CH}}_{\text{3}}\text{)}$ form carbon monoxide has to be explained.

Concept Introduction:

Chemical equation:

In chemical equation, the substance reacts (reactant) to give products.  The number of atoms present in reactant side should be equal to the number of atom present in the product side.
