Determine what is oxidized and what is reduced. The same would be true if the acid was nitric or sulfuric. jayantakumarhotta67 jayantakumarhotta67 Answer: option three is not a … am stands for atomic mass. 17. x(2*am Cu/2*mm CuO) + y(4*am Cu/2*mm) = 0.88 Cu2O Solve the two equations simultaneously for x and y. x gives you grams CuO. CuO(s) + 2 H^+(aq) --> Cu^2+(aq) + H2O(l) This is the net ionic equation. Copper Sulphate pentahydrate (CuSO 4 5H 2 O) is commonly known as Blue Vitriol. What problems would arise from an incomplete reaction? BaCl, +H2SO4→BASO4->2HCI 1 See answer Adityakonamwar is waiting for your help. The general approach is to run a reaction; analyse the results; then write an equation accurately describing the results. Fe203 +3Co->2Fe +3C02 iii., 2K+F2=2KF ív. See the link for additional information. Solved: Identify the oxidizing and reducing agents in the equation. You can write any equation you want to; that doesn’t mean the reaction proceeds thusly. It easily transforms into copper oxide CuO more stable, either in the solid state by a thermal dehydration or at room temperature, in aqueous basic solutions. `CuO(s) + H_2(g) -> Cu(s) + H2O(l)` In this reaction, copper (II) oxide reacts with hydrogen to generate copper metal and water. Write the balanced equation for this reaction. Step 7: CuO(s) + H2SO4(aq)­ -> CuSO4 + H2O(l) – Double Replacement Step 9: Zn(S) + H2SO4(aq) -> ZnSO4(aq) + H2(aq) – Single Replacement 3. In the second step of Reaction I, a. the reaction mixture is diluted with HCl to form CuCl2 b. the reaction mixture is diluted with additional HNO3 to form Cu(NO3)2 c. the reaction mixture is diluted with water to form hexaaquocopper (II) ions d. all of the above are correct 10. In many cases a … CuO+H2 → Cu +H20 11. Start studying Copper lab observations and equations. Add your answer and earn points. The reaction of excess zinc with sulfuric acid is a critical step in this investigation. CuO + H2→ Cu + H2O When copper is heated in the presence of air at high-temperature copper (Cu) goes under an oxidation reaction to give out a black color substance that is a copper oxide (CuO). 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. [Cu(H2O)6]2+ ions are oxidized to copper (II) oxide (CuO) 9. This converts Cu from CuO and Cu from Cu2O to grams Cu that you end up with of 0.88 g. mm stands fr molar mass. Learn vocabulary, terms, and more with flashcards, games, and other study tools. It is obtained in lab by dissolving CuO, Cu(OH) 2 or CuCO 3 in dil H 2 SO 4.The solution on crystallization gives blue triclinic crystals of CuSO 4 5H 2 O.. CuO + H 2 SO 4 → CuSO 4 + H2O Cu(OH) 2 + H 2 SO 4 → CuSO 4 + H 2 O In which of the following chemical equations, the abbreviations represent the correct states of the reactants and products involved at reaction temperature?

If you use 2 HCl(aq), or 2 H^+(aq) + 2 Cl^-, the Cl^- ions would be left out to give the net ionic equation. ) is commonly known as Blue Vitriol cuo + h2o gives commonly known as Blue Vitriol,.
