hree solutions are mixed together to form a single solution. One contains 0.2 mol Pb(C2H3O2)2, the second contains 0.1 mol Na2S, and the third contains 0.1 mol CaCl2. A) Write the net ionic equations for the precipitation reaction or reactions that occur. B) What are the spectator ions in the solution

During trial 2, what allowed you to determine that aluminum was the limiting reactant? check all that apply. all of the copper dissolved. all of the aluminum dissolved. the solution turned clear. the number of grams of copper(ii) chloride used in the reaction was greater than the number of grams of aluminum. the molar ratio of copper(ii) chloride to aluminum was greater than 3: 2, the equation’s molar ratio.
