Robin / Dick Grayson better spend more time in the classroom than in the Batcave! Two "O"s and one "H" is NOT water people!!! He points to the blackboard right at the OH-O and says H 2 0 and mentions this is the chemical for water. What he said is correct, but did he (or the writers) know that water contains 2 Hydrogens and 1 Oxygen? Yes a Batman Riddle, but fundamentally and chemically incorrect as written. And thanks for all your comments!
Let's look at the question in another way. If you were asked to write the chemical symbol for water on the blackboard and you wrote OHO would you be correct? NO!! Water is a molecule consisting of two Hydrogens and one Oxygen. Of course the "2" should be written in subscript indicating the two hydrogen atoms.
