Question

Magnesium hydroxide is an ingredient in some antacids. Antacids react with excess hydrochloric acid in the stomach to relieve
indigestion.
a) balance the reaction that occurs between Mg(OH)2 and HCI.
(select choice) Mg(OH)2 + (select choice) HCI = (select choice) MgCl2 + (blank) H2O

b) what are the mole ratios that would be used to determine the number of moles of MgCl2 produced when HCl reacts with Mg(OH)2.
(blank) mol MgCl2/ (blank) mol Mg(OH)2
(blank) mol MgCl2/ (blank) mol HCI

    Answer:

    a. 2HCl + 1Mg(OH)2 → 1MgCl2 + 2H2O

    b. 1 mol MgCl2/ 1 mol Mg(OH)2

    1 mol MgCl2/ 2 mol HCI

    Explanation:

    a. The reaction of an acid (HCl) with a base (Mg(OH)2) produce water (H2O) and the salt (MgCl2):

    _HCl + _Mg(OH)2 → _MgCl2 + _H2O

    To balance the Cl:

    2HCl + _Mg(OH)2 → _MgCl2 + _H2O

    To balance the oxygen:

    2HCl + _Mg(OH)2 → _MgCl2 + 2H2O

    The reaction is now balanced

    2HCl + 1Mg(OH)2 → 1MgCl2 + 2H2O

    b. Based on the balanced reaction, the moles ratios are:

    1 mol MgCl2/ 1 mol Mg(OH)2

    1 mol MgCl2/ 2 mol HCI
