One Reaction, Three Views

Write 2H₂ + O₂ → 2H₂O. Draw the molecules coming apart and going back together. Describe the pop, the warmth, the mist on the glass.

The drawing is where the disagreement starts — because a drawing lets you put anything you like on the product side, and the most common thing students put there is an atom that was never on the reactant side.
