Chapter 2, Problem 2.58QP

(a)

Interpretation Introduction

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

Concept introduction: The compound which is formed by two nonmetals or metalloids is known as molecular compounds. The building block of these molecules is atoms which are combined through a shared pairs of electrons called 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 ${\text{Mg}}_{\text{3}}{\text{N}}_{\text{2}}$ consists of molecules or ions.

(b)

Interpretation Introduction

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

(c)

Interpretation Introduction

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

(d)

Interpretation Introduction

To determine: If the compound ${\text{NaCl}}_{\text{3}}$ consists of molecules or ions.
