"Water is formed by two molecules of hydrogen and one of oxygen."

Reason: passive voice is most appropriate when the focus is the recipient/result (water) rather than an agent—common in scientific descriptions. (Note: for accuracy and smoother phrasing, say "Water is formed from two hydrogen atoms and one oxygen atom.")
