Chapter 3, Problem 3.128QE

(a)

Interpretation Introduction

Interpretation:

A mixture of antimony atom and ${\text{Cl}}_{\text{2}}$ reacts as given in the question statement.  The balanced equation has to be written.

(b)

Interpretation Introduction

Interpretation:

A mixture of hydrogen and nitrogen gas reacts as given in the question statement.  The balanced equation for this has to be written.  The limiting reactant has to be determined.

Concept Introduction:

Limiting reagent is that reactant of the reaction that controls the amount of product formed.  The limiting agents limit the amount of product and by adding some more amount of the limiting reagent in the reaction mixture, the amount of product can be increased.
