carbon dioxide
The carbon dioxide in your exhaled breath reacts with water in the solution to form carbonic acid. This acidification of the solution causes the pink color of the indicator to change to clear because the pH decreases.
During expiration, carbon dioxide is removed from the body while oxygen is still present in the exhaled air. Water vapor is also expelled during expiration.
Exhaled air from humans contains mainly nitrogen, oxygen, carbon dioxide, and water vapor. Other trace gases found in exhaled air include methane, hydrogen, acetone, and various volatile organic compounds. Factors such as diet, metabolism, and health status can influence the composition of exhaled breath.
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.
carbon dioxide
Exhaled breath is mainly composed of nitrogen, oxygen, carbon dioxide, and water vapor. Therefore, the general chemical formula for exhaled breath would be similar to the chemical composition of air, which is approximately N2 + O2 + CO2 + H2O.

Air- with a lot of carbon dioxide and water vapor.
Since they are carbon dioxide and water they are "exhaled".
Containing carbon dioxide and water is not neutral.
The carbon dioxide in your exhaled breath reacts with water in the solution to form carbonic acid. This acidification of the solution causes the pink color of the indicator to change to clear because the pH decreases.
The respiratory system excretes carbon dioxide and water vapor. Carbon dioxide is eliminated by exhaling it from the lungs, while water vapor is also exhaled as a byproduct of metabolism and respiration.
Exhaled breath primarily consists of nitrogen, oxygen, carbon dioxide, and water vapor. It may also contain trace amounts of other gases and volatile organic compounds originating from the body's metabolic processes or external sources like environmental pollutants or dietary intake.
The two main waste products of respiration are Water (H2O) and Carbon Dioxide (CO2).
The waste product of the respiratory system is carbon dioxide. Oxygen is inhaled into the lungs and carbon dioxide is exhaled out of the body during the process of breathing.
The water vapor in your exhaled breath condenses- it goes from very warm to very cold. The drop in temperature makes the VERY moist exhaled breath condense into water droplets. Those water droplets are visible, just as a cloud is visible.
