Antacid neutralizes stomach acid by the following reaction:
Mg(OH)2 + 2HCl -----> MgCl2 + 2H2O
Calculate the amount of Mg(OH)2 (in grams) needed to neutralize 2.5 grams of HCl.
how many moles of HCL is 2.5 grams? The balanced equation states it will take half that number of moles of magnesium hydroxide
