Approximately 4-5% of expired air is carbon dioxide
It is actually 43.22%.
In my openion it is only .03 %
Carbon Dioxide!
I did not quite get this, but if this helps, good. ( this is from my biology book)"Carbon dioxide is made by cells as a waste product of respiration, and is released across the gaseous exchange surface"
Neither, Nitrogen is 79%, Oxygen is 21% and Carbon dioxide is 0.04%. Carbon dioxide levels have risen from 0.028% at the beginning of the Industrial Revolution, when we began burning fossil fuels (coal, oil and natural gas).
It means that there is more carbon dioxide (unbreathable air) gets in to are air
Carbon dioxide is not an air pollutant. However excessive carbon dioxide release into the atmosphere is a pollutant as it contributes to acid rain
There is 13-16% oxygen in expired air but it depends on your size. See the link below.
Both Inspired and expired air have higher amounts of oxygen than Carbon Dioxide. Inspired air has higher amounts of oxygen than expired, while expired air has higher amounts of Carbon Dioxide than inspired air.
Carbon dioxide is approximately 50 percent heavier than air
0.039 is carbon dioxide
Carbon dioxide constitutes about 0.04% of dry air so the answer is no.
The scientific term for air is "atmosphere." It is a mixture of gases that surround a planet and is composed primarily of nitrogen and oxygen.
carbon dioxide
Carbon Dioxide!
It can't, but it can be measured with a ppm meter. See related link

Carbon dioxide IS air
In the air around you.
