Question

Chapter 21, Problem 21.15CP

Interpretation Introduction

Interpretation:

Whether the given elements are found as carbonates, oxides, sulfides or in uncombined form has to be explained.

Expert Solution & Answer

Explanation of Solution

Given,

General Chemistry: Atoms First, Chapter 21, Problem 21.15CP

Figure 1

In periodic table, the element C is in group IIA and the element is strontium with two valance electrons which can be easily removed to attain +2 oxidation state.
Thus, strontium exist as strontium carbonate.
The element A belongs to first row of transition elements and the element is vanadium. Its common oxidation state are +5, +4, +3, +2. Therefore, vanadium exists as oxides and sulfides.
The element D belongs to transition elements and the element is platinum which exist as uncombined form.
The element B belongs to first row of transition elements and the element is zinc. Its common oxidation state is +2. Therefore, zinc exists as oxides and sulfides.
