Identify the correct order of acidic strength of CO2, CuO, CaO, H2O. CuO + H2SO4 = CuSO4 + H2O(l) Change in Free Energy: ΔG(20C) = -79.9kJ (negative, so the reaction runs) Change in Enthalpy: ΔH(20C) = -85.9kJ (negative, so the reaction is exothermic) This is a double displacement, exothermic reaction. Cupric hydroxide is a weak base. Single-atom site catalysts (SACs) have aroused enormous attention and brought about new opportunities for many applications. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. 3. The reaction of excess zinc with sulfuric acid is a critical step in this investigation. Here, O is removed from CuO, therefore, it is reduced to Cu while O is added to H 2 to form H 2 0, therefore, it is oxidised. Copper oxide react with sulfuric acid to produce copper sulfate and water. © 2021 AeroCare Direct. Some forms of copper(II) hydroxide are sold as "stabilized" copper(II) hydroxide, although they likely consist of a mixture of copper(II) carbonate and hydroxide.
