2. Consider a tank initially containing 5L of 2MCa(OH)2. To this tank, we add 3L of 1.5MHCl and allow the acid-base reaction to proceed to completion. a) At the end of this step, what are the concentrations of all reactants and products involved? We then remove 2L of the contents of the tank, add 2L of 0.5MHCl, and allow the reaction (if any) to proceed to completion. b) What are the concentrations of all reactants and products at the end of the full reaction? Note 1: Water may be generated as part of these reactions. Note 2: You may assume that this reaction occurs at STP where the density of water is 1000kg/m3
