Consider an initial mixture of CH₄ and O₂ represented in the container below: Given the reaction CH₄ + 2O₂ → CO₂ + 2H₂O,which of the following represents a stoichiometric picture of the container after the reaction has gone to completion? E)none of the above

Question

Quizplus · Accepted Answer

The reaction shows that for every one molecule of CH₄, two molecules of O₂ are required. After the reaction completes, all of the CH₄ will have been used up, and the amount of O₂ will have decreased by a factor of two while the amount of the products, CO₂ and 2H₂O, will have increased by the same factor. Thus, the stoichiometric picture should show no more CH₄, half as much O₂, and twice as much of each product. This matches choice C.
