Chapter 9.2, Problem 9.6QAP

Interpretation Introduction

(a)

Interpretation:

To write the mole-mole factor relation between moles of AlCl₃formed from the moles of Cl₂ for the following reaction:

  ${\text{2Al}}_{}\text{(s)}\text{+}3C{l}_{\text{2}}\text{(g)}\to {\text{2AlCl}}_{\text{3}}\text{(s)}$

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 write mole-mole factors relationship between moles of O₂ to react with moles of HCl for the following chemical reaction:

  $\text{4HCl}\text{(g)}\text{+}{\text{O}}_{\text{2}}\text{(g)}\to 2C{l}_{\text{2}}\text{(g)}\text{+}2{\text{H}}_2\text{O(g)}$
