Question

data:
questions:

1. which was more reactive - water or hydrogen peroxide?
2. based on this experiment with water and hydrogen peroxide, would you expect carbon monoxide and carbon dioxide to react the same way when combined with other molecules? explain.

iii. why does carbon monoxide kill?
when you breathe in, oxygen passes from your lungs to your blood.
the oxygen bonds to hemoglobin molecules in the red blood cells.
the red blood cells carry the oxygen to the rest of the bodys cells.

1. how does oxygen move from the lungs to the bodys cells?

at the bodys cells, hemoglobin drops off oxygen and picks up
carbon dioxide. carbon dioxide bonds to hemoglobin at a different
location on the molecule than the oxygen.

1. how does carbon dioxide move from the bodys cells to the

lungs?

Explanation:

1. The table shows hydrogen peroxide had "more reaction" with yeast and an explosion with soap/KI, while water had minimal reactions.
2. CO and CO₂ have different chemical structures (1 vs 2 oxygen atoms), so their reactivity differs like H₂O and H₂O₂.
3. Oxygen bonds to hemoglobin in red blood cells, which carry it to body cells.
4. CO₂ bonds to hemoglobin at a different site, then red blood cells transport it back to lungs.

Answer:

1. Hydrogen peroxide
2. No; they have different numbers of oxygen atoms, so reactivity differs.
3. Oxygen bonds to hemoglobin in red blood cells, which carry it to body cells.
4. Carbon dioxide bonds to hemoglobin (at a different site than oxygen) and is transported back to the lungs by red blood cells.
