Chapter 5, Problem 81E

a)

Interpretation Introduction

Interpretation: The chemical equation for $\text{HCN}$ formed in the given reaction of ${\text{CH}}_{\text{4}}$, ${\text{NH}}_{\text{3}}$ and ${\text{O}}_{\text{2}}$ should be determined. If $20\text{L}$ of reactants are used.

Concept introduction:

• The chemical equation for a reaction is the representation of reaction with an arrow in which reactants are in the left side and products are in the right side of arrow.

• Balance equation is the chemical equation of a reaction which is written according to law of conservation of mass.

• Limiting reagent: limiting reagent is a reactant, which consumes completely in the chemical reaction. The quantity of the product depends on this limiting reagent, it can be determined with the help of balanced chemical equation for the reaction.

• According toAvogadro’s law: the volume of gas is directly proportional to the number of moles of gas at constant pressure and temperature.

  Equation of Avogadro’s law for two gases (1 and two) at constant P and T,

• $\frac{{\text{V}}_{\text{1}}}{{\text{n}}_{\text{1}}}\text{=}\frac{{\text{V}}_{\text{2}}}{{\text{n}}_{\text{2}}}\Rightarrow \frac{{\text{V}}_{\text{1}}}{{\text{V}}_{\text{2}}}\text{=}\frac{{\text{n}}_{\text{1}}}{{\text{n}}_{\text{2}}}$

To determine: The chemical equation for $\text{HCN}$ formed in the given reaction of ${\text{CH}}_{\text{4}}$, ${\text{NH}}_{\text{3}}$ and ${\text{O}}_{\text{2}}$ should be determined. If $20\text{L}$ of reactants are used.
