Chapter 7, Problem 66E

Interpretation Introduction

(a)

Interpretation:

The single replacement reaction $\text{Mg}\left(s\right)+{\text{H}}_{\text{2}}\text{O}\left(l\right)\to$ is to be completed and balanced.

Concept introduction:

In a single replacement reaction, an active metal reacts with water to give a metal hydroxide and hydrogen gas. The general equation for the reaction of a metal and water is shown below.

$\text{Metals}(s)+{\text{H}}_{\text{2}}\text{O}(l)\to \text{metal}\text{hydroxide}(aq)+{\text{H}}_{\text{2}}(g)$

Interpretation Introduction

(b)

Interpretation:

The single replacement reaction $\text{Sr}\left(s\right)+{\text{H}}_{\text{2}}\text{O}\left(l\right)\to$ is to be completed and balanced.
