Carbon dioxide is not a mixture because it is a compound composed of two elements, carbon and oxygen, chemically bonded together in a fixed ratio (1:2). In a mixture, different substances are physically combined and can be separated by physical means, whereas in a compound, the elements are chemically bonded and cannot be easily separated.
What else can I help you with?
How do you say carbon dioxide in french?
dioxyde de carbone
Is carbon an element or mixture?
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.
When you mix carbonated water with juice what makes it foam up?
Carbonated water is water that has had carbon dioxide added to it under pressure. When the pressure is released (say when it is opened), it goes to a lower pressure and releases the carbon dioxide. The foam is an accumilation of carbon dioxide bubbles that float to the top. The juice probably has no affect on it. Its caused by a change in pressure.
Do you capitalize carbon dioxide in a sentence?
Probably since it's a chemical name, I capitalize Oxygen when I say it.
What 3 things does cellular respiration produce?
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.
Is it correct to say that you breathe in oxygen and breathe out carbon dioxide?
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).
Chemical produced when a fuel burns?
It depends on whats burning, but I would say Carbon Dioxide... Please correct me if wrong
How do you say carbon dioxide in french?
dioxyde de carbone
Why could you say that the carbon dioxide and oxygen cycle is balance?
because you take in oxygen and let out carbon dioxide
Why could you say that the oxygen carbon dioxide cycle is balance?
because you take in oxygen and let out carbon dioxide
Is it correct to say that seawater is a mixture?
yes
Is air a compound heterogeneous mixture or a homogeneous mixture?
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.
Is carbon an element or mixture?
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.
Why is it inaccurate to say that we breathe in oxygen and we breathe out carbon dioxide?
It's inaccurate because we actually breathe in a mixture of gases, with oxygen being the most abundant at about 21%. When we breathe out, the air we exhale still contains a significant amount of oxygen along with other gases like nitrogen and some carbon dioxide. The exchange of gases occurs in the lungs, where oxygen is taken up by the blood and carbon dioxide is released.
When you mix carbonated water with juice what makes it foam up?
Carbonated water is water that has had carbon dioxide added to it under pressure. When the pressure is released (say when it is opened), it goes to a lower pressure and releases the carbon dioxide. The foam is an accumilation of carbon dioxide bubbles that float to the top. The juice probably has no affect on it. Its caused by a change in pressure.
Is carbon dioxide a molecule of an element or compound?
carbon dioxide CO2 is a compound because it contains two different elements that is to say carbon and oxygen
Why could you say plants are a sink for carbon?
Plants take in carbon from carbon dioxide in the air and convert it to carbohydrates and keep it with them.
