Exhaled air will contain all of the gases in regular air, except that it will have higher percentages of carbon dioxide and lower percentages of oxygen. (It still will have oxygen, or CPR wouldn't work.)
It will also have water vapor from our lungs. The main gas in inhaled and exhaled air is nitrogen. This is followed by oxygen, then carbon dioxide, then other gases. Yes, there is still more oxygen exhaled than carbon dioxide, but at a smaller percentage than was inhaled. Chances are that your teacher is looking for the gas, carbon dioxide, as your answer, since that is the product of cellular respiration that is disposed of in exhaled air, but it isn't the main component of exhaled air.
Nitrogen is a gas that is present in the same concentration in inhaled and exhaled air, as it is not chemically changed by the body during respiration.
The other gas lost from the body is water vapor, which is exhaled through respiration. Water vapor is a natural byproduct of the body's metabolic processes and is released through the lungs as a component of exhaled air.
Inhaled air has more oxygen compared to exhaled air. When we inhale, we take in fresh oxygen from the environment to use for cellular respiration. As we exhale, we release carbon dioxide and the remaining oxygen that was not used by the body.
Exhaled air typically contains around 4-5% carbon dioxide. The majority of exhaled air is nitrogen, followed by oxygen and then carbon dioxide. This percentage can vary depending on factors such as metabolic rate and lung function.
carbon dioxide
Carbon dioxidenitrogenoxygen
The exhaled gas contain nitrogen, oxygen and carbon dioxide.
The exhaled gas contain nitrogen, oxygen and carbon dioxide.
The exhaled gas contain nitrogen, oxygen and carbon dioxide.
breath
The jar would contain an excess of carbon dioxide due to exhaled breath.
This gas contain nitrogen, oxygen, carbon dioxide.
Nitrogen is a gas that is present in the same concentration in inhaled and exhaled air, as it is not chemically changed by the body during respiration.
Carbon dioxide.
Oxygen is the gas that demonstrates the largest difference in percent between air that is inhaled, and air that is exhaled. The symbol for oxygen is O.
Carbon dioxide (CO2).
Nitrogen is the most abundant gas in the atmosphere ( ~ 80% ) and therefore is the dominant species in both inspired as well as expired air.
