Question

Mr. Micheal is arguing Mr. Tony. Mr. Tony says that if we breakdown 1 water molecule (2 hydrogens and 1 oxygen) we will get Hydrogen gas (2 hydrogens) and Oxygen gas (2 oxygens). Mr. Tony believes this will solve global warming by putting more oxygen into the air. Mr. Micheal says that is inefficient because you would need to breakdown 2 molecules of water to make only 1 oxygen molecule. Who do you agree with? Why?

Answer 1

Answer:

Mr Micheal is correct

Explanation:

From what Mr Tony said, he said if we breakdown 1 water molecule i.e (2 hydrogens and 1 oxygen) $\mathtt{H_2O}$, we'll get (2 hydrogens) and Oxygen gas (2 oxygens).

NO, this claim is wrong,

Dissociation of 1 water molecule results in 1 hydrogen gas and hydroxide and not (2 hydrogens) and Oxygen gas (2 oxygens).

i,e $\mathtt{H_2O \to H^+ + OH^-}$

Mr Micheal says that is inefficient because you would need to breakdown 2 molecules of water to make only 1 oxygen molecule.

Yes, two molecules of water will result in 2 molecules of hydrogen and 1 molecule of oxygen.

$\mathbf{2H_2O \to 2H_2 _{(g)} + O_2_{(g)}}$

Therefore, I agree with Mr Micheal because he is right.
