dioxyde de carbone
Interesting question because everything is a mixture of carbon... But I would say It is an element because it appears on the periodic table of the elements.
Plants take in carbon from carbon dioxide in the air and convert it to carbohydrates and keep it with them.
Carbon dioxide, water, and energy are made during cellular respiration. However, as energy is not a substance, and cannot be made, it is more accurate to say it is released.
The amount of carbon dioxide emitted each year varies according to the amount of forest burnt. However, there is no net increase in atmospheric carbon dioxide from forest fires, as long as the forests are allowed to recover and regrow.AnswerVery little, compared to human emissions. It's hard to say exactly... It is 25.687%, approximately, it is 25.7%it is 25.687%
It is probably more accurate to say that you breath in air, a mixture of gases which contains about 21% oxygen and 0,04% CO2, and you breath out a mixture of gasses which contains a far greater concentration of carbon dioxide than you inhaled (about 5% of the mass of all the exhaled gas).
It depends on whats burning, but I would say Carbon Dioxide... Please correct me if wrong
because you take in oxygen and let out carbon dioxide
because you take in oxygen and let out carbon dioxide
Soda can refer to the chemical compound sodium carbonate, Na2CO3as well as to a fizzy drink. Soda the drink contains amongst other things dissolved carbon dioxide. So I would say it was a mixture.
carbon dioxide CO2 is a compound because it contains two different elements that is to say carbon and oxygen
yes
dioxyde de carbone
It would be a homogeneous mixture in small volumes of space, perhaps as much as a cubic kilometre over an open desert area, say. In larger volumes or near inhabited or forested areas it would be a heterogeneous mixture owing to variations in carbon dioxide content.
This is a reversible change as it involves a change in the state of a substance. Also, by applying pressure and lowering the temperature, gases carbon dioxide can be converted back into dry ice.

Plants take in carbon from the carbon dioxide in the air, and convert it to carbohydrates and store it.
