Chapter 6.7, Problem 1QQ

Interpretation Introduction

Interpretation:

The information contained in the statement that is consistent with the chemical equation $N_2+3H_2\stackrel{}{\to }2N{H}_3$ has to be chosen from the given options.

Concept Introduction:

The coefficients that are present in a balanced chemical equation is like subscripts in the chemical formula.  These coefficients can be interpreted in two levels.  One is a microscopic level and another is macroscopic level.

Microscopic level:

The coefficients that are present in a balanced chemical equation gives numerical relationship between the formula units consumed or produced when a chemical reaction takes place.

Macroscopic level:

In a balanced chemical equation, the coefficients gives information about the fixed molar ratios among the substance that is consumed or produced when a chemical reaction takes place.
