well
it depends on the car. a low-emission car will produce less carbon than a car with bad fuel economy. if a car is idling (not going anywhere) it may produce up to 80% more emission.
Yes. Your carbon footprint is the measure of how much carbon dioxide equivalent you, or any of your activities produce. A car burns petrol (gasoline) so its use has a carbon footprint.
A solar powered car would produce zero carbon dioxide.
Car exhaust fumes produce nitrogen, carbon dioxide and a bit of water vapour. The most toxic part of car gas fumes is carbon monoxide. Factories can also produce carbon monoxide but most of the gas waste is from hydrocarbon gases and nitrogen oxides.
They don't produce more. It is the fact that they are sitting there doing nothing and using petrol for no reason is why it is bad.
No. helium does not produce carbon dioxide
Just about all the gases that are in car exhaust, including carbon monoxide, methane, and hydrogen.
Animals produce carbon dioxide. Animals produce carbon dioxide
No elements combine to produce carbon. Carbon is an element in and of itself.
No, burning hydrogen produces only water, it does not produce carbon or carbon dioxide.
Yes, forest fires do produce carbon dioxide.
