Aluminum hydroxide (Al(OH ) 3) is often present in antacids to neutralize stomach acid (HCl). The reaction occurs as follows: Al(OH ) 3(s) + 3HCl(aq) AlC l 3(aq) + 3 H 2O(l). If 14.0 g of Al(OH ) 3 is present in an antacid tablet, determine the theoretical yield of AlC l 3 produced when the tablet r
