Chapter 8.1, Problem 8.6QAP

Interpretation Introduction

(a)

Interpretation:

The number of atoms of each element in the following reactants and in the products should be determined.

  ${\text{2N}}_{\text{2}}\left(\text{s}\right){\text{ + 3O}}_{\text{2}}\left(\text{g}\right)\to {\text{2N}}_{\text{2}}{\text{O}}_{\text{3}}\left(\text{g}\right)$

Concept Introduction:

In order to find the number of atoms in a molecule, multiply the coefficient placed before the molecule with the subscript of each atom of the element in the molecule.

Interpretation Introduction

(b)

Interpretation:

The number of atoms of each element in the following reactants and in the products should be determined.

  ${\text{Al}}_{\text{2}}{\text{O}}_{\text{3}}\left(\text{s}\right)\text{ + 6HCl}\left(\text{aq}\right)\to {\text{3H}}_{\text{2}}\text{O}\left(\text{l}\right){\text{ + 2AlCl}}_{\text{3}}\left(\text{aq}\right)$

Concept Introduction:

In order to find the number of atoms in a molecule, multiply the coefficient placed before the molecule with the subscript of each atom of the element in the molecule.

Interpretation Introduction

(c)

Interpretation:

The number of atoms of each element in the following reactants and in the products should be determined.

  ${\text{C}}_{\text{5}}{\text{H}}_{\text{12}}\left(\text{l}\right){\text{ + 8O}}_{\text{2}}\left(\text{g}\right)\to {\text{5CO}}_{\text{2}}\left(\text{g}\right){\text{ + 6H}}_{\text{2}}\text{O}\left(\text{g}\right)$

Concept Introduction:
