Hi, I'm Robin Higgins, and this is the air-to-fuel ratio for the combustion of carbon monoxide. Alright, so let's break down what we're looking at. First of all, we know that we're reacting carbon monoxide, and we can find the structure through it's name. So, we have only one carbon, because they would have told us if we had two or more. We know we only have one oxygen because of the prefix mono. So, this is our structure for carbon monoxide. Now, we know we're going to have carbon monoxide undergo combustion, which means it reacts with oxygen gas. It's actually just air. This is the part of air that reacts. So, now we have to find our product. And, combustion reactions always combine to form carbon dioxide. So, you can see the difference between this, carbon dioxide, the prefix di means two, so we have two oxygen's. And, now, we have to balance the equation. Well, starting here, we have one carbon, one carbon, that works. But, over here, we have three oxygen's, and only two over here. That means we're going to have to bump this number up to two. Now, we have two carbons, two carbons, that works, and now we have four oxygen's, here, and four oxygen's, here, so we're completely balanced. So, the original question was "what is the air-to-fuel ratio?" In this case, our air is oxygen and their fuel is carbon monoxide. So, the ratio is two to one. Air is one, carbon monoxide is two. I'm Robin Higgins, and this is "what is the ratio of combustion for carbon monoxide?"
