Carbon dioxide

Carbon dioxide

The gas you breath out is the same as the gas you breath in, except that it has a bit less oxygen (O2) in it and it has notably more carbon dioxide (CO2) in it.

Carbon Dioxide.

air dummy

Water vapor.

You breathe out water particles and carbon dioxide. Like if you breathe on a window, here will be a small circle of fog where you breathed...that is the water sticking to the glass. And then you breathe out carbon dioxide which plants take in and then it goes through photosynthesis. Through photosynthesis, plants will release oxygen so we can go through cellular respiration. Hope I answered your question good enough
air that contains mostly carbon-di-oxide[CO2]

Answer 2

The gases in gas we exhale are mostly carbon dioxide and 4% to 5% less oxygen than was inhaled. Additionally, vapors and trace gases are present: 5% water vapor, several parts per million (ppm) of hydrogen & carbon monoxide, 1 ppm of ammonia and less than 1 ppm of acetone, methanol, ethanol and other volatile organic compounds.
