Chapter 17, Problem 10RQ

(a)

Interpretation Introduction

Interpretation:

More reactive metal in $\text{Mg}$ and $\text{Ca}$ has to be determined.

Concept Introduction:

Oxidation process represents loss of electrons. Reduction process represents gain of electrons. Oxidation numbers are the part of system that is formed to track electrons in reaction.

Series formed after arrangment of elements in increasing order of standard reduction potential is called electrochemical series.

Metals placed above in electrochemical series from hydrogen have very negative reduction potential and thus they are better reducing agent. Metals placed below from hydrogen in electrochemical series have positive reduction potential and thus they tend to act as an oxidizing agent in a redox reaction.

(b)

Interpretation Introduction

Interpretation:

More reactive metal in $\text{Fe}$ and $\text{Ag}$ has to be determined.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

More reactive metal in $\text{Zn}$ and $\text{H}$ has to be determined.

Concept Introduction:

Refer to part (a).
