3. 1反应①中Cu化合价升高,被氧化,为还原剂,由反应①可知氧化性Fe 3+>Cu 2+,由反应②可知氧化性Cu 2+>Fe 2+,则氧化性Fe 3+>Cu 2+>Fe 2+, 故答案为:CuFe 3+>Cu 2+>Fe 2+2当有0.2mol电子转移时,生成0.1molCl 2,标准状况下体积为2.24L,故答案为:2.24L 3①铜与稀硝酸反应生成硝酸铜、NO和水,反应的离子方程式为3Cu+8H ++2NO 3-=3Cu 2++2NO↑+4H 2O, 故答案为:3Cu+8H ++2NO 3-=3Cu 2++2NO↑+4H 2O ②放到铜粉和稀硫酸中,能实现铜粉溶解,所加物质在酸性条件下应具有强氧化性,题中KNO 3和CuNO 32符合,故答案为:AC ③ag铜粉与足量的某浓度HNO 3溶液完全反应后,产生VL标准状况气体, 则生成nCuNO 32= mol, 气体可能为NO或NO 2,物质的量共为 mol, 则根据N元素守恒可知反应中消耗的HNO 3的物质的量是2nCuNO 32+n气体=2× mol+ mol= + mol, 故答案为: + mol.
4. Recently, the price of bitcoin rebounded and rebounded. The exchange rate of one bitcoin against the US dollar rose above 58000, and the one-day increase expanded to over 9.0%, reaching a new high in the short term. This boosted the morale of the market, and at the same time put an end to the volatile and declining market in the past. However, in the face of the recent bitcoin price trend, some investors have negative emotions and are not optimistic about it: "when people are not optimistic about it, it will rise " of course, the market trend of cryptocurrency led by bitcoin can not be explained by the simple and crude statement that" it will rise if you don't value it ", because any investment contract is basically based on the market. If the market affirms and pursues its value, it will naturally be reflected in the price on the contrary, when the market sentiment of bitcoin is negative or depressed, the price of one dollar will also show some performance. Generally, it is normal for bitcoin to continue to fluctuate and fall. The number of burst positions and the funds involved will also increase, and batch after batch of investors will be forced to burst out. But "not optimistic about rising" shows that some investors are extremely difficult to predict price changes the price range of bitcoin is relatively small: at present, the price of bitcoin is about 57300 US dollars, down 0.85%, which is close to 500 US dollars compared with the previous trading day. The fluctuation range is relatively small, and the price is changing all the time on the last trading day, bitcoin broke through US $58000, and now there is a stampede above the intensive trading area. Appropriate callback is in line with the market operation, and generally will not have a fundamental change to the market trend
