The principle carbon emission from cars is carbon dioxide. There is some carbon monoxide in the direct engine exhaust if the engine does not have the right air/fuel mixture. This is usually removed by proper operation (since 1975) of the catalytic converter.
Virtually ANY carbon-based fuel, when burnt, or as the chemists call it, when "oxidized", will give off carbon monoxide. It is a natural byproduct of the chemical reactions that take place in any location where oxygen and carbon come in contact with each other.
Carbon from the fuel and oxygen coming into the engine from the air inducted into the engine in massive amounts.
Different elements and chemical substances absorb and emit different wavelengths on the electromagnetic spectrum. Carbon dioxide is colorless because the wavelengths that it absorbs and emits are chiefly in the infrared region of the spectrum, which is invisible to human eyes. If human eyes could detect infrared radiation, then we would not think that carbon dioxide is colorless. If our eyes were not able to detect the hazy green wavelengths emitted by chlorine gas, then we would say that chlorine gas is colorless instead of green, and it would never have gotten the name that stems from the Greek word for "green". Some objects that emit only in the nonvisible portion of the spectrum appear black instead of clear like carbon dioxide. The reason carbon dioxide doesn't appear black is that it is so rarified, being a gas, that most light passes through it instead of being absorbed.
Frozen carbon dioxide, also known as dry ice, is a wonderful resource for making certain types of special effects, such as mysterious boiling cauldrons that emit a visible, dense vapor as they boil. It is also sometimes used when the temperature of regular ice is just not cold enough for your purposes.
Ethanol is a fuel made from plants. When we burn this fuel, it does emit carbon dioxide, but of course this was originally absorbed from the atmosphere by the plants, so there is no net increase in the amount of atmospheric carbon dioxide no matter how much ethanol we use (apart from a small amount produced by generating electricity used in the production of the ethanol). A disadvantage of using ethanol for motor fuel is that its production competes with food crops.
Both. Cars emit Hydrocarbons + Nitrogen Oxides + Carbon Dioxide + Carbon Monoxide. People emit Methane and Carbon Dioxide.
Cars run on burning of fossil fuel, which is mainly hydrocarbons, compound of carbon and hydrogen which on oxidation (burning) produces Carbon dioxide, water (and Carbon Monoxide if oxygen is not sufficient for combustion).
very little since the invention of catalytic converters.
No, electric cars don't emit carbon dioxide but some electricity comes from fossil fuels which releases carbon dioxide. Although electrics are don't emit pollution, there are still some drawbacks. Electric cars are inefficient, they can only power up to a certain speed and the fuel needs to be filled up often.
no
because gas powered cars emit carbon dioxide which is killing the earth!
Humans emit carbon dioxide by breathing. They also emit carbon dioxide by belching and they emit methane by farting.
Yes, I think soil can emit carbon dioxide into the atmosphere.
no
Its not. Carbon Dioxide is a gas that trees and plants ingest and we emit.
Animals emit carbon dioxide. Plants consume carbon dioxide.
Yes,I think we breath it out and plants get it and they give us oxegen which we breath and than emit carbon dioxide
