Le Châtelier's principle applies to gas exchange reactions in human lungs. Carbon dioxide gas combines with water in the blood to form carbonic acid:
H2O + CO2 = H2CO3
When you breathe more rapidly, the concentration of CO2 in your blood
decreases. How would this affect the concentration of H2CO3?

A. It would increase it.
B. More information is needed to assess how it would be affected.
C. It would remain stable.
D. It would decrease it

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
