Hydrogen, since in H2O there are two hydrogen atoms per one oxygen atom. So the hydrogen atoms would run out first so that there are 12 H2O molecules, where all the hydrogen is used and there are 12 oxygen atoms left over

Determine if each statement below is True or False regarding Arrhenius and Br∅nsted-Lowry definitions for acids and bases.

Answer:

All statements are true

Explanation:

Arrhenius theory:-

The Arrhenius theory was introduced introduced by Swedish scientist named Svante Arrhenius in 1887.

According to the theory, acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion, $H^+$ .

Hence, statement 1 is correct.

Bronsted-Lowry base is the specie which accepts the proton form the medium. For example, Benzoate ion is the conjugate base of the benzoic acid. It is a Bronsted-Lowry base and the dissociation of benzoate ion can be shown as:-

$C_6H_5COO^-_{(aq)} + H_2O_{(l)}\rightleftharpoons C_6H_5COOH_{(aq)} + OH^-_{(aq)}$
