Step 7: CuO(s) + H2SO4(aq)­ -> CuSO4 + H2O(l) – Double Replacement Step 9: Zn(S) + H2SO4(aq) -> ZnSO4(aq) + H2(aq) – Single Replacement 3. You can write any equation you want to; that doesn’t mean the reaction proceeds thusly. CuO+H2 → Cu +H20 11. Start studying Copper lab observations and equations. 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. Add your answer and earn points. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Write the balanced equation for this reaction. 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. Determine what is oxidized and what is reduced. See the link for additional information. What problems would arise from an incomplete reaction? If you do not know what products are enter reagents only and click 'Balance'. 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. 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 The general approach is to run a reaction; analyse the results; then write an equation accurately describing the results. The reaction of excess zinc with sulfuric acid is a critical step in this investigation. 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. `CuO(s) + H_2(g) -> Cu(s) + H2O(l)` In this reaction, copper (II) oxide reacts with hydrogen to generate copper metal and water. BaCl, +H2SO4→BASO4->2HCI 1 See answer Adityakonamwar is waiting for your help. am stands for atomic mass. jayantakumarhotta67 jayantakumarhotta67 Answer: option three is not a … Solved: Identify the oxidizing and reducing agents in the equation. [Cu(H2O)6]2+ ions are oxidized to copper (II) oxide (CuO) 9. In many cases a … The same would be true if the acid was nitric or sulfuric. Copper Sulphate pentahydrate (CuSO 4 5H 2 O) is commonly known as Blue Vitriol. Fe203 +3Co->2Fe +3C02 iii., 2K+F2=2KF ív. Click here👆to get an answer to your question ️ Identify the oxidising agent (oxidant) in the following reactions. CuO + H2→ Cu + H2O 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. 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. 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). CuO(s) + 2 H^+(aq) --> Cu^2+(aq) + H2O(l) This is the net ionic equation. 17.
