Answer 1

Numerically correct, physically incorrect.

Explanation:

That is the simplest form of the balanced net equation for the formation of water from hydrogen and oxygen.

However, we don't find `1/2` of diatomic molecules (`O_2)` floating about. The physical combination would really be 2 moles of hydrogen combining with one mole of oxygen to produce 2 moles of water:

`2H_2 + O_2 -> 2H_2O`
