Question 1:Hard to consider....the % relate to the air pressure and the temperature and the mositure...
Question 2: 79% Nitrogen and 20% Oxygen.....( I mean the VOLUME but not MASS. Completely unlike the dissolved
Question 3: Faint...if the air didn't dissolved in water and all the fish ...all the animal live in water will die....so easily to understand.
