When did the carbon-oxygen cycle start to change?
In my own opinion and un-tested hypothesis.... that carbon oxygen cycle start to change when there is no more plants to give oxygen and get carbon dioxide and there is no animals and humans that inhale oxygen and give off or exhale carbon dioxide.
What substance will the carbon in methane change into when it burns in oxygen?
In carbondioxide: CH4 + 3 O2 ==> CO2 + 2 H2O
We inhale oxygen and exhale carbon dioxide as a result of a change in our bodies. a. physical b. chemical?
We inhale oxygen and exhale carbon dioxide as a result of a change in our bodies. Answer - Chemical Change
What type of change is oxygen turning into carbon dioxide?
Chemical
Why do plants need carbon dioxide and nort oxygen?
because they need carbon dioxide for photosynthesis they are just like humans but they take in carbon dioxide and then change it to oxygen and release it in the air
How does oxygen concentration change with relation to carbon dioxide?
Oxygen concentration tends to decrease as carbon dioxide levels increase. This is due to the fact that high carbon dioxide levels can displace oxygen in the air, leading to lower oxygen concentrations. Therefore, there is an inverse relationship between oxygen and carbon dioxide concentrations in the atmosphere.
How does carbon move or change in tree growing?
because they dont have oxygen
How will you describe the sequence of oxygen and carbon dioxide?
Oxygen in & carbon dioxide out. The change occurs within the cells and blood carries the gasses between the lungs and the cells.
Is a carbon atom combines with two oxygen atoms to form carbon dioxide a physical change?
No, the combination of a carbon atom with two oxygen atoms to form carbon dioxide is a chemical change because the atoms are rearranging to form a new substance with different properties.
Why do the totals of carbon dioxide and oxygen not change?
i don't completely under stand your question, but if you're asking why the amount of it in the air doesn't change, the answer is simple. we breathe in oxygen and let out carbon dioxide. while plants "breathe in" carbon dioxide and let out oxygen. oxygen is also made from chemical reactions from the ocean. but this is not enough to supply this much life with oxygen, and we still don't know where all the extra oxygen came from.
Is fire in a fireplace a chemical change?
Yes, burning of carbon with oxygen to carbon dioxide. C + O2 --> CO2
Carbon can react with oxygen to form carbon dioxide. Which of the following statements about this chemical change is true?
This is an oxidation reaction.
