Write a net chemical equation for the reaction that took place when koh was added. (remember the solubility rules for precipitation reactions. omit states-of-matter from your answer. use the lowest possible whole number coefficients.)

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.
