Tums® tablets contain calcium carbonate (CaCO3), which neutralizes stomach acid (HCl). The balanced reaction is:  CaCO3 (s)  +  2 HCl (aq)  ⟶   CaCl2 (aq)  +  H2O(l)  +  CO2 (g) If a patient has 0.200 mol of stomach acid (HCl) to neutralize, and enough Tums were taken to completely neutralize it, how many grams of H2O will form? Hint: molar mass of H2O is 18.02 g/mol

Consider the following reactions:   2Mg(s) + O2​(g) ⟶ 2MgO(s)  2KClO3​(s)⟶ 2KCl(s) + 3O2​(g)  CH4​(g) + 2O2​(g) ⟶ CO2​(g) + 2H2​O(g)  HCl(aq) + NaOH(aq) ⟶ NaCl(aq) + H2​O(l)  AgNO3​(aq) + NaCl(aq) ⟶ AgCl(s) + NaNO3​(aq)  CaO(s) + H2O(l) ⟶ Ca(OH)2 (aq) Which reaction(s) is/are double displacement – precipitation reactions?
