Question

Chapter 21, Problem 16E

Interpretation Introduction

(a)

Interpretation:

Whether MgO have high melting point or BaO should be determined.

Concept introduction:

Melting point of a substance refers to the temperature at which it will begin to melt. An oxide refers to a chemical compound which is formed by the reaction of a metal and oxygen and it consists of at least one atom of oxygen.

Interpretation Introduction

(b)

Interpretation:

Whether MgF2 have greater solubility in water or MgCl2 should be determined.

Concept introduction:

In a solution, the solute is the minor component which is dissolved in some solvent which is larger in quantity. The polarity of water is responsible for making it as a good solvent. When polar compounds are added to water they get broken into their smaller constituents or dissolve in water to become a part of the solution.
