1. Write a balanced equation for the reaction of sodium hydroxide with hydrochloric acid. Calculate the number of moles of each reagent you used in the reaction. Use the balanced equation to determine which reagent was limiting, and how many moles reacted (show all your calculations for full credit). Was the acid or the base the limiting reagent? 2. Calculate the value of the enthalpy change (ΔHrxn) in units of kJ/mol for the reaction of NaOH (aq) + HCl (aq). Is the reaction an endothermic or exothermic process?
