Here is the solution to the remaining part of question 19. Questions 20 and 21 were addressed in the previous response. 19. Milk of Magnesia and Heartburn c) The neutralization reaction between Magnesium Hydroxide (Mg(OH)_2) and Hydrochloric Acid (HCl) produces Magnesium Chloride (MgCl_2) and Water (H_2O). Step 1: Write the unbalanced equation with state symbols. Mg(OH)_2(s) + HCl(aq) → MgCl_2(aq) + H_2O(l) Step 2: Balance the chlorine atoms. There are 2 Cl on the right and 1 on the left. Place a coefficient of 2 in front of HCl. Mg(OH)_2(s) + 2HCl(aq) → MgCl_2(aq) + H_2O(l) Step 3: Balance the hydrogen and oxygen atoms. There are 2 H (from Mg(OH)_2) + 2 H (from HCl) = 4 H atoms on the left. There are 2 O atoms on the left. To balance, place a coefficient of 2 in front of H_2O. Mg(OH)_2(s) + 2HCl(aq) → MgCl_2(aq) + 2H_2O(l) Step 4: Verify all atoms are balanced. Mg: 1 on left, 1 on right. O: 2 on left, 2 on right. H: 4 on left, 4 on right. Cl: 2 on left, 2 on right. The balanced chemical equation for this neutralization reaction is: Mg(OH)_2(s) + 2HCl(aq) → MgCl_2(aq) + 2H_2O(l)
