This question concerns the stochiometry of gases

Question

Carbon monoxide, C0, reacts with oxygen to produce carbon dioxide. How many liters of oxygen are required to react with 5.0 L of C, and how many liters of C02 are produced by the reaction?

Answer 1

First thing we must do is to write the correctly balanced equation:

2CO + O₂ ==> 2CO₂ .. balanced equation

Next, we can now use the stoichiometry of this equation to answer the question:

-How many liters of O₂ are required to react with 5.0 L of CO?

5.0 L CO x 1 L O₂ / 2 L CO = 2.5 L O₂ required

-How many L of CO₂ are produced?

5.0 L CO x 2 mol CO₂ / 2 mol CO = 5.0 L CO₂ produced .. or

2.5 L O₂ x 2 mol CO₂ / 1 mol O₂ = 5.0 L CO₂ produced
