Chapter 1: Problem 2

Which of the following pairs of elements is most likely to create an interstitial alloy? (A) Titanium and copper (B) Aluminum and lead (C) Silver and tin (D) Magnesium and calcium

Short Answer

Expert verified
The most likely pair of elements to create an interstitial alloy is (D) Magnesium and Calcium, due to the significant difference in their atomic radii.

Step by step solution

01

Understand interstitial alloys

Interstitial alloys are a type of alloy where smaller atoms fill the gaps between larger metal atoms. These alloys have different properties than their base metals, including increased hardness and strength.
02

Compare the atomic radii of the elements in option A

The atomic radius of Titanium is approximately \(147pm\) and that of Copper is \(128pm\). The difference in size is small, making it less likely for an interstitial alloy to be formed.
03

Compare the atomic radii of the elements in option B

The atomic radius of Aluminum is approximately \(143pm\) and that of Lead is \(175pm\). Although Lead has a larger atomic radius, the difference is not significant enough for an interstitial alloy to be formed.
04

Compare the atomic radii of the elements in option C

The atomic radius of Silver is approximately \(160pm\) and that of Tin is \(140pm\). The difference in size is small, making it less likely for an interstitial alloy to be formed.
05

Compare the atomic radii of the elements in option D

The atomic radius of Magnesium is approximately \(150pm\) and that of Calcium is \(197pm\). The difference in size is significant, making it possible for an interstitial alloy to be formed.

When calcium chloride \(\left(\mathrm{CaCl}_{2}\right)\) dissolves in water, the temperature of the water increases dramatically. Which of the following must be true regarding the enthalpy of solution? (A) The lattice energy in \(\mathrm{CaCl}_{2}\) exceeds the bond energy within the water molecules. (B) The hydration energy between the water molecules and the solute ions exceeds the lattice energy within \(\mathrm{CaCl}_{2}\) . (C) The strength of the intermolecular forces between the solute ions and the dipoles on the water molecules must exceed the hydration energy. (D) The hydration energy must exceed the strength of the intermolecular forces between the water molecules.

A bottle of water is left outside early in the morning. The bottle warms gradually over the course of the day. What will happen to the pH of the water as the bottle warms? (A) Nothing; pure water always has a pH of 7.00. (B) Nothing; the volume would have to change in order for any ion concentration to change. (C) It will increase because the concentration of \(\left[\mathrm{H}^{+}\right]\) is increasing. (D) It will decrease because the auto-ionization of water is an endothermic process.
