Chapter 21, Problem 20PS

Interpretation Introduction

Interpretation:

To compare the mass of ${\text{H}}_{\text{2}}\left(\text{g}\right)$ expected from the reaction of steam per mole of methane, petroleum and coal.

Concept introduction:

The formula for methane is ${\text{CH}}_{\text{4}}$ and coal is $\text{C}$. Petroleum is a hydrocarbon with a general formula of ${\text{C}}_n{\text{H}}_{2n+2}$.

All of them reacts with steam to produce carbon monoxide and water. $\text{1 mole}$ of these substances produce different moles of hydrogen. The conservation of mass should be followed for any chemical reaction.
