Write the balanced equation for this reaction. Add your answer and earn points. 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. 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. Click hereðto get an answer to your question ï¸ Identify the oxidising agent (oxidant) in the following reactions. 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 â CuSO 4 + H2O Cu(OH) 2 + H 2 SO 4 â CuSO 4 + H 2 O CuO(s) + 2 H^+(aq) --> Cu^2+(aq) + H2O(l) This is the net ionic equation. am stands for atomic mass. 17. Solved: Identify the oxidizing and reducing agents in the equation. CuO + H2â Cu + H2O The reaction of excess zinc with sulfuric acid is a critical step in this investigation. Learn vocabulary, terms, and more with flashcards, games, and other study tools. You can write any equation you want to; that doesnât mean the reaction proceeds thusly. Start studying Copper lab observations and equations. 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). [Cu(H2O)6]2+ ions are oxidized to copper (II) oxide (CuO) 9. The same would be true if the acid was nitric or sulfuric. In which of the following chemical equations, the abbreviations represent the correct states of the reactants and products involved at reaction temperature? `CuO(s) + H_2(g) -> Cu(s) + H2O(l)` In this reaction, copper (II) oxide reacts with hydrogen to generate copper metal and water. See the link for additional information. 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. 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. Step 7: CuO(s) + H2SO4(aq)­ -> CuSO4 + H2O(l) â Double Replacement Step 9: Zn(S) + H2SO4(aq) -> ZnSO4(aq) + H2(aq) â Single Replacement 3. 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. Copper Sulphate pentahydrate (CuSO 4 5H 2 O) is commonly known as Blue Vitriol. Fe203 +3Co->2Fe +3C02 iii., 2K+F2=2KF ív. Determine what is oxidized and what is reduced. If you do not know what products are enter reagents only and click 'Balance'. jayantakumarhotta67 jayantakumarhotta67 Answer: option three is not a â¦ BaCl, +H2SO4â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. What problems would arise from an incomplete reaction? 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. CuO+H2 â Cu +H20 11.
