A hydrogen from one molecule and an oxygen from the other molecule.
Hi!
I'm not entirely sure about this so I'm sorry if I'm wrong but I think it would be helium.
Again in not entirely sure but i hope this helped you, i hope you have a great day, afternoon, or night!
TITRATION is the process of reaching equilibrium between acids and bases.
The molecular formula should have been give to you from ur teacher
It would help if I could see the specific answer choices, but an environment that would have lots of oxygen, water, decaying organisms and sunlight would be the answer (ex. the forest or riverbed)
