Chapter 2, Problem 2.57QP

(a)

Interpretation Introduction

Interpretation: The compounds that consist of molecules and those that consist of ions are to be identified.

Concept introduction: The compound which is formed by two nonmetals or metalloids is known as molecular compounds. The building blocks of these molecules are atoms which are combined through a covalent bond. The compounds which are formed by combination of metals and non-metals are known as ionic compounds. These metals and nonmetals are held together by the strong electrostatic forces.

To determine: If the compound ${\text{P}}_{\text{4}}{\text{O}}_{\text{10}}$ consists of molecules or ions.

(b)

Interpretation Introduction

To determine: If the compound ${\text{SrCl}}_{\text{2}}$ consists of molecules or ions.

(c)

Interpretation Introduction

To determine: If the compound ${\text{MgF}}_{\text{2}}$ consists of molecules or ions.

(d)

Interpretation Introduction

To determine: If the compound ${\text{SO}}_3$ consists of molecules or ions.
