What effect does rapid exhalation of co2 during exercise have on the concentration of h2co3 in the blood?

Humans breathe in oxygen and breathe out carbon dioxide.During the process of breathing, humans convert sugar into energy. Carbon dioxide is a waste product of this process. Carbon dioxide is released into the blood, travels to the lungs and is exhaled. Because carbon dioxide is a weak acid, the more carbon dioxide in the blood, the more acidic the blood becomes.

The correct answer is

Aluminum, boron, and gallium are likely together in one group because they have the same number of valence electrons, and carbon and germanium are likely together in another group because they have the same number of valence electrons.

This is the only one that makes sense after reviewing the data. Hopefully this helps! Feel free to mark as brainliest!
