Complete these sequential reactions, including phases: 3. Na2O(s) + H2O(l) → Na2CO3(s) H₂O Na2CO3(s) H₂O + Ba(OH)2(aq) → + Ba(OH)2(aq) → + 2HCl(aq) → 4. In the Ba(OH)2 tests shown in the previous problem, what difference would you expect to observe? Why would it be a problem if you don't dissolve the decomposition product completely before adding barium hydroxide? 5. Sample calculation: If you perform a similar experiment decomposing Cu(OH)2 according to the following equation, starting with 6.831 g of Cu(OH)2, how much CuO should you get, in grams? Cu(OH)2(s) CuO(s) + H2O(g) ->
