(a) $2HCl(aq) + SrO(s) -- \gt H_2O(l) + SrCl_2(aq)$ (b) $2HCl(aq) + Na_2O(s) -- \gt H_2O(l) + 2NaCl(aq)$ (c) $2HCl(aq) + Li_2O(s) -- \gt H_2O(l) + 2LiCl(aq)$ (d) $2HCl(aq) + BaO(s) -- \gt H_2O(l) + BaCl_2(aq)$
An acid-metal oxide reaction follows the pattern: $Acid + Metal$ $oxide --\gt Water + Salt$ Therefore, in this type of reaction, the hydrogen in the acid will react with the $O^{2-}$ ions to produce water molecules, and the conjugate base will make an ionic compound (salt) with the metal. ** Hint: To determine the salt, put the anion from the acid, and the possible cation from the oxide (the metal) together. 1. Write the reaction following this pattern. 2. Balance the chemical equation.
