Question

3.0 PROCEDURE: For each reaction, you should write a total molecular reaction, a total ionic reaction and then remove any spectator ions to produce a final net ionic reaction. In order to simplify your task each reaction has its driving force listed. In more advanced General Chemistry courses, you will be expected to find the driving force yourself (based on the rules given above), but for our purposes it is best for you to simply "experience the steps of producing final net ionic equations. Keep in mind that all the equations should be balanced. Although, you should formally write each state symbol, you may omit all of the (aq) references for this exercise. We will ASSUME everything is aqueous unless stated otherwise. Therefore, it is very important for you to include ANY AND ALL state symbols for chemicals which are not aqueous be they solids, liquids or gases. Also remember the hydronium ion, H,0*, is associated with acids. When preparing an ionic form always ionize a strong acid or a soluble salt (hydroxide bases follow the solubility rules). Leave molecules such as carbon dioxide, water, ammonia Etc. unionized and do not ionize weak acids. So here we go ....

Answer 1

ANSWER=

(1) Lead(II) nitrate and magnesium sulfate solution are combined

Balanced molecular reaction: MgSO₄(aq) + Pb(NO₃)₂ (aq) = Mg(NO₃)₂(aq) + PbSO₄(s)

Total ionic reaction: Mg²⁺(aq) + SO₄^2-(aq) + Pb²⁺ (aq) + 2NO₃^- (aq) = Mg²⁺(aq) + 2NO₃^- (aq) + PbSO₄(s)

Net Ionic reaction: SO₄^2-(aq) + Pb²⁺ (aq) = PbSO₄(s)

(2)Barium metal is dropped into hydrochloric acid

Balanced molecular reaction: Ba(s) + 2HCl(aq) = BaCl₂(aq) + H₂(g)

Total ionic reaction:   Ba(s) + 2H⁺(aq) + 2Cl^-(aq) = Ba²⁺(aq) + 2Cl^-(aq) + H₂(g)

Net Ionic reaction: Ba(s) + 2H⁺(aq) = Ba²⁺(aq) + H₂(g)

(3)Potassium hydroxide solution reaction with nitric acid

Balanced molecular reaction: KOH(aq) + HNO₃(aq) = KNO₃(aq) + H₂O(l)

Total ionic reaction: K⁺(aq) + OH^-(aq) + H⁺(aq) + NO^3-(aq) = K⁺(aq) + NO^3-(aq) + H₂O(l)

Net Ionic reaction: OH^-(aq) + H⁺(aq) = H₂O(l)
