answer to #28

A first approach is to indicate the reactants and products in a word equation: copper(II) oxide + sulfuric acid → copper(II) sulfate + water
Next, convert the word equation to a skeleton equation using chemical formulas: CuO(s) + H2 SO4 (aq) → CuSO4 (aq) + H2 O(l)
Because the Cu2 + is exchanged in this reaction involving an aqueous solution, and the molecular compound H2 O is formed, the reaction type is double-replacement. In this case, the skeleton equation
already is balanced. Inspection of substances on the left and right of the equation shows that the same relative amounts (number of atoms) of each element are present in the reactants and the products.
