Interpretation Introduction

(a)

Interpretation:

The number of moles of Br2 (l) required to completely react with 0.557 grams of Al(s) should be calculated.

Concept Introduction:

It is important to recognize that the coefficients in a balanced equation give the relative number of molecules.

Because atoms are not changed or destroyed in a chemical reaction one must always balance a chemical reaction. That is, one must choose the coefficients that gives the same number of each type of atoms on both sides, using the smallest set of integers.

Interpretation Introduction

(b)

Interpretation:

The number of moles of HClO4 (aq) required to completely react with 0.557 grams of Hg(s) should be calculated.

Concept Introduction:

It is important to recognize that the coefficients in a balanced equation give the relative number of molecules.

Because atoms are not changed or destroyed in a chemical reaction one must always balance a chemical reaction. That is, one must choose the coefficients that gives the same number of each type of atoms on both sides, using the smallest set of integers.

c

Interpretation Introduction

Interpretation:

In this subpart one must calculate how many moles of Cl2 (g) is required to completely react with 0.557 grams of CH4 (g).

Concept Introduction:

d

Interpretation Introduction

Interpretation:

In this subpart one must calculate how many moles of P (s) is required to completely react with 0.557 grams of K(s).

Concept Introduction:
