The media often adds to the confusion because their inability to discern the two gases adds to the issue. Countless stories abound about injuries or fatalities from CO poisoning when a gas fired generator is run inside a dwelling during natural disasters like hurricanes. During the last decades increased focus on greenhouse emissions have led to a heightened awareness of CO2 especially from automobiles. This confusion can often be overwhelming too leading some to dismiss the gases and the issues they cause altogether.
CO can be a flammable gas in higher concentrations sometimes referred to as C1D1 or C2D2 environments and devices to measure carbon monoxide in these concentrations are normally designed to be explosion-proof.
Those are vastly different levels. The range of concentrations is from 0 to 1,, For example, it is easier to write that the CO2 level in a room has risen from ppm to ppm than to write the CO2 level has risen from 0. However, both are correct. Read more about parts-per-million here. This is how we get English words like a tri angle 3 sides , the US Penta gon a 5 sided-building , or deca thlon 10 contests.
So the first half of mono xide means 1 oxygen atom, and the first half of di oxide means 2 oxygen atoms. For the second half of each word, we have oxide. Oxide is the name for a simple compound of oxygen with another element or group.
For example, add oxygen to the element hydrogen and you get hydrogen di oxide H20 , or water. Other oxides you may have heard of are nitrous oxide NO2 - laughing gas , or zinc oxide ZnO - the active ingredient in sunscreen.
In conclusion, regardless of what industry you work in, leaks and overexposure to both gases can occur around you each and every day. Recently publicized fatalities involving both CO2 and CO have refocused attention on the need to accurately and effectively detect and monitor for the presence of gases. Understanding the gases and being able to prevent potential injuries and hazards from occurring is the best preventive first step you can take.

And, of, course the atmosphere is not going to run out of carbon dioxide molecules. They're just going to keep replacing them. But they keep settling into this top layer, this surface layer, of my water.
So it's actually looking already really different than what was happening on the other side. We only had a little bit of oxygen but now I've got tons of carbon dioxide. And I don't want to make it uneven. I mentioned before, we have nitrogen-- so let me still draw a bunch of nitrogen-- that will outnumber the carbon dioxide dramatically. So it'll look something like that. But there's lots and lots of carbon dioxide there.
In fact, if I was to calculate the concentration on this side, the concentration would be pretty high. It would be 7. And Again, these numbers, I'm assuming that I'm doing the experiment. This is the number I would find if I actually did the experiment. So it's a much bigger number than I had over here. On the oxygen side, the number was actually pretty small, not very impressive.
And yet on the carbon oxide side, much, much higher. Now that's kind of funny. It might strike you as kind of a funny thing.
Because look, these partial pressures are basically the same. I mean, not even basically, they're exactly the same. There's no difference in the partial pressure. And yet the concentrations are different.
So if you keep the P the same, the only way to make for different concentrations is if you have a different constant. So let me actually move on and figure out what the constant is. So what do you think the constant on this side would be, higher or lower? Let's see if we can figure it out together. The K sub H on this side is going to be lower.
It's going to be lower. It's 29 liters times atmosphere divided by moles. So it's a much lower number. And I don't want you to get so distracted by this bit. This is kind of irrelevant to what we're talking about. It's just the units, and we can change the units to whatever we want. But it's this part-- it's the fact that the number itself on the carbon dioxide side is lower. Now let's think back to this idea of Henry's law.
Henry's law told us that the partial pressure, this number, tells you about what's going to be going into the water, and that the K sub H tells you about what's going out of the water. And so if what's going in on both sides is equivalent, then really the difference is going to be what's the leaving. Carbon dioxide naturally occurs in the atmosphere at about parts per million — humans and animals breathe in oxygen and exhale carbon dioxide — we can tolerate a small amount of it.
However, carbon monoxide does not occur naturally in the atmosphere and can cause health problems even in low concentrations. The density of both gases is also different. Carbon dioxide is heavier than air and gas detectors should be put nearer the ground, whereas carbon monoxide is slightly lighter and detectors should be placed higher up.
We are often asked if a carbon monoxide detector will measure carbon dioxide levels, and vice versa.
