Chapter 2, Problem 10A

Interpretation Introduction

Interpretation: With reference to the various characteristics of magnesium given one physical property of magnesium needs to be identified.

Concept introduction: All matters have physical and chemical properties which help in the identification of that particular matter.

Answer to Problem 10A

One physical property of magnesium is that magnesium metal is very malleable.

Explanation of Solution

Physical properties are those properties of matter which can be easily measured without change in the sample’s composition. For example, mass, color, and volume.

On the other hand, chemical properties can be defined as when a substance changed into new substances by chemical reaction which involves change in the composition of original substance. Examples are reactivity, flammability, and the ability to rust.

When $Mg$ is stretched to make long ribbons it do not becomes other compound but remains magnesium with different appearance.

If $Mg$ is ignited in Bunsen burner it reacts with oxygen to form magnesium oxide.

The reaction: $Mg+\frac{1}{2}{O}_2\to MgO$

This is a chemical property because $MgO$ have different physical or chemical properties as compared to $Mg$ metal.

Conclusion

Thus, one physical property of magnesium is that magnesium metal is very malleable.
