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 decrease it
D) It would remain stable

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
