7. complete the dissociation equations for each of the following substances in water. make sure you balance the equations.\na. ag₂s(s) →\nb. ch₃oh(l) →

Answer

Explanation:

Step1: Dissociate silver sulfide

Silver sulfide ($Ag_2S$) dissociates into silver ions ($Ag^+$) and sulfide ions ($S^{2 -}$). The balanced equation is based on the conservation of atoms. $$Ag_2S(s)\rightleftharpoons 2Ag^+(aq)+S^{2 -}(aq)$$

Step2: Consider methanol dissociation

Methanol ($CH_3OH$) is a covalent - compound and does not dissociate into ions in water in the traditional sense of ionic dissociation. It simply dissolves as molecules. $$CH_3OH(l)\rightleftharpoons CH_3OH(aq)$$

Answer:

a. $Ag_2S(s)\rightleftharpoons 2Ag^+(aq)+S^{2 -}(aq)$ b. $CH_3OH(l)\rightleftharpoons CH_3OH(aq)$
