because the bubbles are air the air can't fuse with hydrogen to become water because there is no excess hydrogen so it goes to the air as bubbles
Hot bubbles
You have to swim through an underwater maze. Pop bubbles for oxygen.
Jump and tuck your head and exhale through your nose and just keeping practicing!! 
This is the easiest way to not hold your nose underwater. When you go underwater, blow bubbles out of your nose. This will prevent the water from entering your nose. Just blow bubbles out of your nose frequently and no water will get up your nose.
sometimes they like to go underwater (they can breath under water because the hairs on theirbody make air bubbles)!
Cutting the stem of hydrilla underwater can prevent air bubbles blocking the xylem.
NO!!! THe bubbles do NOT contain sodium bi-carbonate. Sodium b-carbonate will undergo thermal decomposition or acid reaction to produce bubbles of Carbon Dioxide. He is the reaction Eq;n. 2NaHCO3 + 2HCl = 2NaCl + H2O + 2CO2(g) [ Bubbles]
The player was unable to exhale after suffering a hit.
lots of bubbles come out and it's a sort of gurgling noise
Leaves have gaseous exchange through its stomata or free cell surface (in case of water plants). These gases come out in the form of bubbles in water. Hence air bubbles are formed when leaves are in water.
Yes you can, but you would have to hold your breath and make sure that you exhale quickly, because underwater there is no oxygen. You will hear it but the projectile will not go as fast because the water will slow it down. You would not be able to fire another shot unless you supply your own oxygen or surface and inhale.
Why would you need to? If you're writing a story, you don't write things like "bloop" or "splash" - you let the reader imagine those sounds for themselves. Write what is happening to make bubbles, and they'll figure out what it sounds like.
