1. Write the dissociation chemical equations: (a) - Write the reaction where $H_2SO_4$ gives a proton to a water molecule: $H_2SO_4(aq) + H_2O(l) \lt -- \gt HS{O_4}^-(aq) + H_3O^+(aq)$ (b) - Write the reaction where $HS{O_4}^-$ gives a proton to a water molecule: $HS{O_4}^-(aq) + H_2O(l) \lt -- \gt S{O_4}^{2-}(aq) + H_3O^+(aq)$ (c) - Write the reaction where $H_3O^+$ gives a proton to a water molecule: $H_3O^+(aq) + H_2O(l) \lt -- \gt H_2O(l) + H_3O^+(aq)$ (d) - Write the reaction where $N{H_4}^+$ gives a proton to a water molecule: $N{H_4}^+(aq) + H_2O(l) \lt -- \gt NH_3(aq) + H_3O^+(aq)$
