Write the equation for the dissolution of each sample in water. Then determine the number of moles of each ion produced as well as the total moles of ions produced. 1 mol aluminum chloride 1 mol sodium sulfide 0.5 mol barium nitrate

Insoluble sulfide compounds are generally black in color. which of the following combinations could yield a black precipitate? check all that apply. na2s(aq)+kcl(aq) li2s(aq)+pb(no3)2(aq) pb(clo3)2(aq)+nano3(aq) agno3(aq)+kcl(aq) k2s(aq)+sn(no3)4(aq)
