Chapter SH, Problem 19.4APP

To determine

To state: Formula of the compound represented by X.

Answer to Problem 19.4APP

Formula of the compound represented by X is CO.

Explanation of Solution

Introduction:

One of the compounds is represented by X in the following reaction:

  ${\text{BaCO}}_3+\text{C}+{\text{H}}_2\text{O}\to \text{Ba}{\left(\text{OH}\right)}_2+2\text{X}$

A compound that can replace X in the equation is CO. Hence, the equation can be written as follows:

  ${\text{BaCO}}_3+\text{C}+{\text{H}}_2\text{O}\to \text{Ba}{\left(\text{OH}\right)}_2+2\text{CO}$

The number of all the atoms on both sides of the equation remains the same, hence verifying the answer.

Conclusion:

Formula of the compound represented by X is CO.
