What is the difference between air and carbon dioxide (CO)?
The difference is so slight that CO is found to evenly distribute itself indoors. It is worth mentioning that CO indoors is usually generated from incomplete combustion (heat source) and therefore traveling in a warm air stream. Warm air is more buoyant and does rise. Coupling this fact with the knowledge that CO is lighter than air…
Why do lighter gases collide faster than heavier gases?
Assuming the two gases are ideal, both are therefore at the same pressure. Since the temperatures are the same, both gases have the same average KE. The lighter gas will therefore have a higher average speed than the heavier gas. Its collision frequency is therefore greater.
Is CO a light gas?
CO is slightly lighter than air and mixes throughout the atmosphere. It is a by-product of incomplete combustion, produced when fuels such as natural gas, propane, heating oil, kerosene, coal, charcoal, gasoline or wood are burned with insufficient air.
Is carbon monoxide or air much heavy?
Accepting the simplification that air is essentially 79% nitrogen gas and 21% oxygen gas, calculation reveals that CO gas is approximately 3% lighter than gaseous air.
Which gas is heavier CO or CO2?
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.
Is carbon a heavy gas?
Answer 3: Carbon has an atomic weight of 12, oxygen in diatomic form(O2) of 32 and CO2 of 44. This means that the mass of 6x1023 atoms of CARBON has a mass of 6 kilograms, the mass of 6x1023 diatomic oxygen molecules is 32 kg, and for CO2 it is 44kg. So carbon is the lightest and CO2 the heaviest.

Is carbon monoxide the same density as air?
This is because CO2 is more dense than air (about 2.0 kg/m3 for CO2 compared to about 1.2 kg/m3 for air, at a typical temperature and pressure). If the tank instead contained carbon monoxide gas, the gas would be found throughout the room. This is because CO gas is about the same density as air.
What is the difference between air and carbon monoxide?
Is it Heavier Than Air? Carbon monoxide is also known as the “silent killer” since it's an odorless, colorless, and tasteless gas. It's slightly lighter than air but not enough to rise to the ceiling in a room. Instead, it tends to disperse itself, mixing with the air and spreading throughout a space.
Which is more deadly, CO or CO2?

What is the reaction of carbon monoxide and alkenes?
In the presence of strong acids and water, carbon monoxide reacts with alkenes to form carboxylic acids in a process known as the Koch–Haaf reaction. In the Gattermann–Koch reaction, arenes are converted to benzaldehyde derivatives in the presence of AlCl 3 and HCl.
How many electrons are in a carbon atom?
Carbon and oxygen together have a total of 10 electrons in the valence shell. Following the octet rule for both carbon and oxygen, the two atoms form a triple bond, with six shared electrons in three bonding molecular orbitals, rather than the usual double bond found in organic carbonyl compounds. Since four of the shared electrons come from the oxygen atom and only two from carbon, one bonding orbital is occupied by two electrons from oxygen, forming a dative or dipolar bond. This causes a C←O polarization of the molecule, with a small negative charge on carbon and a small positive charge on oxygen. The other two bonding orbitals are each occupied by one electron from carbon and one from oxygen, forming (polar) covalent bonds with a reverse C→O polarization since oxygen is more electronegative than carbon. In the free carbon monoxide molecule, a net negative charge δ – remains at the carbon end and the molecule has a small dipole moment of 0.122 D.

How long has carbon monoxide been around?
Humans have maintained a complex relationship with carbon monoxide since first learning to control fire circa 800,000 BC. Primitive caveman probably discovered the toxicity of carbon monoxide poisoning upon introducing fire into their dwellings. The early development of metallurgy and smelting technologies emerging circa 6,000 BC through the Bronze Age likewise plagued humankind from carbon monoxide exposure. Apart from the toxicity of carbon monoxide, indigenous Native Americans may have experienced the neuroactive properties of carbon monoxide though shamanistic fireside rituals.
What is the chemical formula for carbon monoxide?

It is the simplest molecule of the oxocarbon family. In coordination complexes the carbon monoxide ligand is called carbonyl .
What is the most significant source of CO?
The most significant source of human-produced CO is formed during combustion when there is insufficient oxygen (O2) to produce carbon dioxide (CO2). Imagine where this scenario may take place… does a hot water closet come to mind? How about a furnace located in a crawlspace or attic? Or a poorly vented kitchen with a gas stove?
Why does CO smell?
Because it cannot be noticed without a detector or meter, CO has earned the dubious name of “silent killer.” When folks call and say they can “smell carbon monoxide,” they are usually referring to other combustion byproducts that the human nose can detect. If you can smell combustion byproducts there is a problem that should be addressed ASAP.
What is the bond between CO and hemoglobin?
CO bonds to hemoglobin (Hb), and instead of carrying oxygen (O2) the hemoglobin is then occupied with CO – creating carboxyhemoglobin (HbCO). CO poisoning is actually the result of the head and heart not receiving sufficient oxygen… or asphyxiation.
How many people die from CO poisoning?
CO poisoning is the most common type of fatal indoor air poisoning in countries where cooking and heating is still dominated by fires. More than 500 Americans die each year from unintentional carbon monoxide poisoning. Symptoms of mildly acute CO poisoning include lightheadedness, nausea headaches, fatigue, and flu-like symptoms.
How long do CO alarms last?
Gas sensors in CO alarms have a limited lifespan, generally less than 6 years. The test button on common CO alarms only tests the battery, not the CO gas sensor. It is recommended that CO gas sensors be periodically tested and calibrated by exposing them to a known amount of CO.
How much CO should be in an alarm?
Most CO alarms sold today in the US will not sound an alarm until concentrations greater than 50-70 parts per million (ppm) are reached. Many believe CO alarms should signal at far lower levels. In fact, the Building Biology guideline is that indoor CO should never exceed outdoor concentrations. Where we live, in the San Francisco Bay Area, it is rare to detect more than 1 ppm in outdoor air unless you are standing near an active flue or chimney.
What is the CA bill for CO alarms?
California Senate Bill 183 requires CO alarms for any dwelling unit with a fuel-burning appliance, fireplace or attached garage. This accounts for the vast majority of residential buildings in CA.

How long has CO2 been around?
There is a detailed scientific record of atmospheric carbon dioxide dating back to 800,000 years back. To fully comprehend the variations of CO2 before 1958, scientists make use of ice cores. Research has to lead to the drilling of the icepack into Greenland and Antarctica which are thousands of years old.
Why do both gases have the same average KE?
Since the temperatures are the same, both gases have the same average KE. The lighter gas will therefore have a higher average speed than the heavier gas. Its collision frequency is therefore greater. Although the collisions are less frequent, the heavier gas has more momentum. Because of this, it strikes the sides of its container with more force, albeit less often. Supposedly, this makes up for the lower collision frequency in the heavier gas. This is why both gases have the same pressure. Is there any way to prove this in the ideal case?
What are the two ideal gases?
Assume there are two ideal gases. The first is made of a light particle, and the second is made of a heavy particle. The two are of the same amount, in the same volume container, and at the same temperature. Assuming the two gases are ideal, both are therefore at the same pressure.
How to find the pressure of a gas?
Ok, I believe I figured this out. The pressure of each gas is proportional to the force with which the collide and the frequency of each collision. The force with which they collide is also proportional to the momentum of the particles. Therefore, the pressure is proportional to the collision frequency and momentum. The frequency of collision for the light particles is: f L = x f H , and the ratio of the pressures is P L / P H = ( x / x ∗ ρ H ∗ x f H) / ρ H ∗ f H = 1 / 1 = 1 , therefore the pressures must be equal.
Is the pressure of a gas proportional to the force of the collision?
The pressure of each gas is proportional to the force with which the collide and the frequency of each collision. The force with which they collide is also proportional to the momentum of the particles. Therefore, the pressure is proportional to the collision frequency and momentum.
Why is the gas composition changing?
One reason the gas composition is changed is economic. Since some heavier hydrocarbons and condensates have more value. For example if there are significantly high content of propane, butane, and pentane in the gas, it maybe advantages to take those out and sell them as LPG or LNG which is liquid.
Why does CO2 rise?
Probably you get the incorrect impression that CO2 is rising when it is produced by combustion of any hydrocarbon fuel (of bio or fossil origin). It is the principal component of the flue gases (apart from water) produced in such combustion. The whole flue gases are hot and therefore have much lower density than air. We always see smoke from anything burning going straight up. The hot air balloons go up due to the same reason. Thanks to buoyancy of hot gases for these phenomena. But as these heavy gases cool, they do come down due to the higher force of gravity acting on these. However, thermal inter-diffusion of gases results in quick dispersion of all constituents of air to form a homogenous mixture, showing very little stratification with altitude.
What is the composition of natural gas?
The natural gas as it comes out of the well can have differing compositions of methane, ethane, and heavier hydrocarbons (propane, butane,…). The net molecular weight depends on the exact composition. Here is a sample comparison of compositions:
Why are some of the other answers more reasonable, but none of them are complete?
Some of the other answers are more reasonable, but none of them are complete because none fully address the issues touched on by Moalem’s answer.
How long does it take for natural gas to rise?
However, the natural gas as a whole body will rise within a few seconds. (Initially, it will accelerate upwards at a small fraction of ~10 m/s².) So, on the important time scale (several minutes), there is only one natural gas body, and only one way that this body goes: up.
What is the mass density of natural gas?
The default values of density from this site Natural Gas Density Calculator yield a natural gas mass density of 0.712 kg/m³ vs. 1.204 kg/m³ for air. 0.7<1.2.
Why is gas processed?
One reason the gas is processed is for pollution control. Some components like acid gases are removed from the gas before feeding it into the pipeline that serves the city to prevent toxicity, corrosion and pollution. One reason the gas composition is changed is economic.
