《化学反应原理》第一章测试题（The chemical reaction principle the first chapter test） The chemical reaction principle the first chapter test A choice (this includes 10 items, each item of 2 points, a total of 20 points, every day there is only one right answer) 1. the future of new energy is rich in resources, in the use of no environmental pollution or little pollution, and some can be recycled. The following is the most promising new energy is () The natural gas of the coal and nuclear power. The fuel cell and solar power and wind energy A. the B. 5 6 7 4 8 C. 3 4 5 6 D. in addition to the outside 2.1g carbon and the amount of water vapor reaction of CO and H2, 10.94KJ need to absorb heat, thermochemical equation this reaction (for) A.C + H2O = CO + H2; H== +131.3KJ mol?- B. C (s) + H2O (g) = CO (g) + H2 (g); H== +10.94KJ mol?- C. C (s) + H2O (L) = CO (g) + H2 (g); H== +131.3KJ mol?- D. C (s) + H2O (g) = CO (g) + H2 (g); H== +131.3KJ mol?- The 3. piece of iron on zinc and filled with salt water and the surface of phenolphthalein dish, as shown in figure. The first observed the phenomenon of phenolphthalein red region (is) A.I and III B.I and IV C.II and III D.II and IV 4. CuCl2 and NaCl mixed solution electrolysis, anode and cathode respectively. The material is () A.H2 Cl2 and B. Cu and Cl2 C. H2 and O2 D. Cu and O2 5. electrolysis saturated salt water, when 0.8molNaOH is formed near the cathode, the amount of material through the electronic wire is () A.0.16mol B. 0.2mol C. 0.4mol D.0.8 mol 6. on iron products with a certain thickness of the zinc layer, the plating solution is proper () A and zinc as the anode, iron as cathode, cathode containing Fe2+ B, solution of zinc, iron products as the anode, the solution containing Zn2+ C, as the cathode zinc, iron anode, anode containing Fe3+ D, solution of zinc, iron as cathode, the solution containing Zn2+ In the 7. U tube, using a mixture of inert electrode electrolysis of sodium sulfate and litmus, after a period of time, can be o
