Is the burning of petrol in cars an example of complete combustion or incomplete combustion Explain?
The burning of petrol in cars is typically an example of complete combustion where petrol (hydrocarbon) reacts with oxygen to produce carbon dioxide and water. However, in some cases, incomplete combustion can occur, leading to the production of carbon monoxide, particulate matter, and unburnt hydrocarbons due to insufficient oxygen supply or improper engine functioning.
Why unburnt carbon particles are present in luminous zone?
Unburnt carbon particles are present in the luminous zone of a flame due to incomplete combustion. In this region, insufficient oxygen and lower temperatures prevent the complete oxidation of carbon-containing fuels, resulting in the formation of soot or carbon particles. These unburnt particles emit light, contributing to the flame's luminosity. Additionally, turbulent mixing and varying fuel-to-air ratios also play a role in the presence of these particles.
Why the central blue cone in the blue flame is unburnt gas?
because no air enters it. The air burns gas.
What is the spectrum of burning kerosene?
Burning kerosene produces a visible light spectrum that includes mainly yellow, orange, and red colors. The colors seen depend on various factors such as temperature, combustion efficiency, and impurities in the kerosene.
Why is petrol not good?
petrol produces 3 prominent harmful gases when burned in an internal combustion engine. * nitrogen oxides * carbon monoxide * unburnt hydrocarbons. carbon monoxide is a well known poison that replaces oxygen in the blood that results with the brain being starved of oxygen. nitrogen oxides are less well known, at high concentrations they can cause respiratory diseases but their biggest effect is that at helping to cause photochemical smog, a reaction that takes place in the atmosphere envolving free radicals, sunlight and NO2 gases that produce a very unhealthy fog such as which can be seen over Bejing. unburnt hydrocarbons are often carcenogenic. catalytic converters try to reduce the quantites of the first two by creating CO2 and nitrogen however CO2 is obviously a huge contributor to the well kown green house effect.
Why a car with a catalytic converter still produces pollution?
The converter does not remove all pollution. It just helps "clean" some of it up. It converts nitrous oxides, carbon monoxide, unburnt hydrocarbon, and oxygen into water, nitrogen, and carbon dioxide. It is not 100% efficient.The converter does not remove all pollution.

What is purpose of catalytic converter for cars?
It stops the car from emitting harmful gasses by the following reactions: Carbon monoxide and nitrogen monoxide into carbon dioxide and nitrogen gas Unburnt hydrocarbons into carbon dioxide and water
What does a catalytic converter do on a 1997 dodge 5.9l?
It converts carbon monoxide, nitrous oxides and unburnt fuel into carbon dioxide, nitrogen, and water vapor.It converts carbon monoxide, nitrous oxides and unburnt fuel into carbon dioxide, nitrogen, and water vapor.
Why are catalytics used in car exhasts?
When a gasoline engine runs it produces a lot of carbon monoxide, and some nitrogen dioxide and also passes through some traces of unburnt vaporized fuel. Carbon Monoxide and unburnt fuel are bad for the environment, and NO2 is bad for people. A catalytic process is a chemical process that changes a substance. The catalytic converter turns the unburnt fuel vapor and carbon monoxide into carbon dioxide, a much less harmful substance, and water (this is why water drips from the tailpipes of gas engined cars). It breaks the nitrogen dioxide or NO2 into simple nitrogen. Mandating use of catalytic Converters lowered pollution emissions that cause smog, especially in dense urban environments, though some people feel that modern cars are efficient enough they no longer need the expensive heavy part.
What gasses does a 3 way catalytic converter treat?
carbon monoxide, unburnt hydrocarbons and oxides of nitrogen
The function of a catalytic converter is to?
Convert unburnt fuel, carbon monoxide, and nitrogen oxides into nitrogen, water, and carbon dioxide.
What do car exhaust fumes contain?
Carbon dioxide, carbon monoxide, nitrous oxides, water vapor, oxygen, unburnt hydrocarbons,
How is unburnt hydrocarbons made into less harmful substances by a catalytic converter?
By giving the hydrogen a handjob
What is two advantages of a four stroke cycle engine over a two stroke cycle engine?
Pollution - 4 stroke has far less unburnt hydrocarbon in the exhaust.
How do catalytic converters reduce the amount of polluting gases released by cars?
They convert nitrous oxides, unburnt fuel, and carbon monoxide to water, carbon dioxide and nitrogen.
Can an unburnt gas leak cause ill-health in humans?
Unburnt gas leak is probably referring to natural gas. The gas is mostly methane which is odorless, that's why they add that additional 'rotten-egg' smell to make it noticable. That smell isn't a health concern, though the gas is a hydrocarbon and probably has some health risks if exposed to it for a long period of time.
What four emissions do biodiesel- diesel- gasoline- and petrol-fueled cars generate?
The main tail pipe emissions are carbon dioxide, carbon monoxide, water, nitrous oxide, and unburnt hydro carbons.
