Where does oxygen come into the process of carbion monoxide emissions from cars...?

Question

since what is put in cars is a hydrocarbon chain?

Answer 1

if we ignore passengers, groceries, etc, then there are 2 things put into cars.

1.  hydrocarbon chain

2.  air.

and of the two, by weight, (or volume, your choice) there is far more air.

tuning an engine is fairly critical.  too little gas and the engine sputters and runs poorly.  too much, (ie too little air for the gas) and burning is incomplete, and black smoke, along with CO comes out of the tail pipe.

Answer 2

Oxygen comes into play any time u burn anything it is called oxidation and it will always produce CO2. Most energy is produced in the oxidization of Corbin.

Answer 3

Carbon Monoxide is formed by the incomplete combustion of a hydrocarbon. Carbon monoxide is a toxic gas.

When additional oxygen is added the combustion goes to Carbon Dioxide, which is much less toxic than Carbon Monoxide. Carbon Dioxide is a gas that can be used by plants to make food, such as sugars and starch, and cellulose, which is the structural component of plants.

Answer 4

From the air.

Answer 5

when oxygen is the limiting regent in a combustion reaction, as in...not enough to fully react all of the hydrocarbon molecules involved in the reaction to form CO2+H20, CO(carbon monoxide) is formed instead.

this occurs in all combustion reactions, because it is impossible to achieve complete combustion, so some CO is always formed in any combustion reaction.

less oxygen supplied, the more CO is produced.

Answer 6

Simple ... the oxygen comes from the atmosphere.  Our atmosphere is about 20% oxygen.

Answer 7

When cars burn fuel, they expose the hydrocarbon to oxygen in order to get the combustion reaction (burning). CO, among other things, is formed in that process as the emissions waste.

Answer 8

Carbon monoxide is the product of the incomplete combustion of carbon-containing compounds, notably in internal-combustion engines.



Carbon monoxide is a significantly toxic gas and is the most common type of fatal poisoning in many countries.[15] Exposures can lead to significant toxicity of the central nervous system and heart. Following poisoning, long-term sequelae often occur. Carbon monoxide can also have severe effects on the fetus of a pregnant woman. OSHA limits workplace exposure levels to 35 ppm. Symptoms of mild poisoning include headaches and dizziness at concentrations less than 100 ppm. Concentrations as low as 667 ppm can cause up to 50% of the body's hemoglobin to be converted to carboxy-hemoglobin (HbCO) and ineffective for delivering oxygen. Exposures of this level can be life-threatening.

The mechanisms by which carbon monoxide produces toxic effects are not yet fully understood, but hemoglobin, myoglobin, and mitochondrial cytochrome oxidase are thought to be compromised. Treatment largely consists of administering 100% oxygen or hyperbaric oxygen therapy, although the optimum treatment remains controversial.[16] Domestic carbon monoxide poisoning can be prevented by the use of household carbon monoxide detectors.
