Although zinc hydroxide is insoluble in water, it reacts with an aqueous solution of hydrochloric acid to produce zinc chloride and water:
Zn(OH)2(s) + 2 HCl(aq) → ZnCl2(aq) + 2 H2O(l)
3.45 g of Zn(OH)2 react with 10.50 g of HCl. Calculate the number of moles of excess reagent when the reaction is complete.
