Curious artist, not a chemist, kinda dumb boi looking for some kind galaxy brains here.
Okay. So. I have this planet. Its atmospheric composition is fairly earthlike: 21.6% O2, 77% N2, 0.2% CO2, 0.4% Ar, and 0.7% SO2, with the remaining 0.1% being other gases. The surface of the planet is mostly covered in oceans, so I imagine that there's gonna be some dilute sulfuric acid in them cuz of the SO2 interacting with water and oxygen.
What I'm really interested in knowing is how the little sulfur dioxide could affect biochemistry. I already kinda feel like most life is gonna stick to the ocean, since I know for a fact that it's gonna rain H2SO4 and surviving on land would be the opposite of fun (even tho I have plans to make land organisms that maybe have a shell of some sort? I was thinking SiC but, like, again, I have no idea if it would even work).
What would these organisms use in place of our biomolecules? And what kind of protection would they use against the sulfuric acid rains? These are pretty much my main questions.
Thank y'all in advance <3 <3
