Chapter 9.2, Problem 9.7QAP

Interpretation Introduction

(a)

Interpretation:

To determine the moles of O₂ required to react with 2.6 mol of H₂.

  ${\text{2H}}_{\text{2}}\text{(g)}\text{+}{\text{O}}_{\text{2}}\text{(g)}\to {\text{2H}}_2\text{O(g)}$

Concept Introduction:

A stoichiometric coefficient of a well-balanced chemical equation tells about the relative relation between moles of reactants used and moles of products formed.

Lets say we have a chemical reaction as:

  $\text{aA}\text{+bB}\to \text{cC}\text{+}\text{dD}$

If above reaction is well-balanced then,

  'a' moles of A reacts with b moles of B to produce c moles of C and d moles of D.

Interpretation Introduction

(b)

Interpretation:

To determine the moles of H₂ required to react with 5.0 mol of O₂.

  ${\text{2H}}_{\text{2}}\text{(g)}\text{+}{\text{O}}_{\text{2}}\text{(g)}\to {\text{2H}}_2\text{O(g)}$

Interpretation Introduction

(c)

Interpretation:

To determine the moles of H₂O produce from 2.5 mol of O₂.

  ${\text{2H}}_{\text{2}}\text{(g)}\text{+}{\text{O}}_{\text{2}}\text{(g)}\to {\text{2H}}_2\text{O(g)}$
