CuO + H 2 SO 4 → CuSO 4 + H 2 O. When H2O is added to CuSO4, a simple reaction occurs resulting in the formation of copper sulfate pentahydrate (CuSO4.5H2O), which is also known as blue vitriol. A balanced chemical equation is one in which the number of atoms of each element are the same on both the reactant and the product side of the equation. Reactant side (1mol Cu,5moles of O,2moles of H and 1mol of S). Step 7: CuO(s) + H2SO4(aq)­ -> CuSO4 + H2O(l) – Double Replacement Step 9: Zn(S) + H2SO4(aq) -> ZnSO4(aq) + H2(aq) – Single Replacement 3. So as N2 is oxidised from -3 to 0, and Cu reduced from +2 to 0, we multiply the compound reduced by 3 and oxidised by 2 and maintain with no.
