From the balanced molecular equations, write the complete ionic and net ionic equations for the following: (a) k2 c2 o4(aq) + ba(oh)2(aq) ⟶ 2koh(aq) + bac2 o4(s)
(b) pb(no3)2(aq) + h2 so4(aq) ⟶ pbso4(s) + 2hno3(aq)
(c) caco3(s) + h2 so4(aq) ⟶ caso4(s) + co2(g) + h2 o(l)

Which statement is true about ionic compounds?

Explain the relationship between forward and backward reactions in equilibrium, and predict how changing the amount of a reactant (creating a tension) will affect that relationship.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
