Chapter 9.1, Problem 2PP

Interpretation Introduction

Interpretation:

The skeleton equation for the following word equation needs to be determined.

$\text{Carbon}\text{monoxide}\left(\text{g}\right)+\text{Oxygen}\left(\text{g}\right)\to \text{Carbon}\text{dioxide}\text{(g)}$

Concept introduction:

A skeleton equation is the way of writing chemical reaction taking the help of chemical formulas that represent substances taking part in the reaction. To write the skeleton equation, the chemical symbols of the compounds should be known.

Answer to Problem 2PP

The skeleton equation for the word equation is,

$\text{CO}(g)+{\text{O}}_{\text{2}}(g)\to {\text{CO}}_2(g)$

Explanation of Solution

To determine the skeleton formula of a reaction, one must know the chemical symbols of elements and compounds.

The formula of carbon monoxide, oxygen and carbon dioxide are $\text{CO}\text{,}{\text{O}}_{\text{2}}\text{and}{\text{CO}}_2$.

So, the skeleton equation is,

$\text{CO}(g)+{\text{O}}_{\text{2}}(g)\to {\text{CO}}_2(g)$

Conclusion

Skeleton equation can be written if the reactants and products are known.
