【题目】二草酸合铜(Ⅱ)酸钾品体(K2[Cu(COa)]2H2O)(摩尔质量为354gmol1),是一种工业用化工原料。微溶于冷水和酒精,虽可溶于热水但会慢慢分解,干燥时较为稳定,温度高于260C易分解。实验室以胆矾和草酸为原料制备二草酸合铜(Ⅱ)酸钾品体的流程如下,请根据相关流程回答(已知H2C2O加热CO↑+CO_2↑+H_2...
Water splitting via two two-electron processes (the H2O first photocatalytically converted to H2 and H2O2 under visible light irradiation and then the H2O2 disproportionation to H2O and O2 by a thermal catalytic process) has attracted extensive attention recently.1,2 Contrary to these reports, we ...

(1)造成酸雨的气体是二氧化硫和氮氧化物,反应物中含有硫元素,根据元素守恒知,该气体是二氧化硫;再根据元素守恒知,另一种气体是氢气,所以该反应的反应物是硫化亚铜和水蒸气,生成物是铜、氢气和二氧化硫,反应条件是高温,所以该反应方程式为:Cu2S+2H2O(g) 2Cu+2H2↑+SO2↑,故答案为:Cu2S+2H2O(g) 2Cu+2H2↑+...

逐渐增大,同一主族,从上到下,第一电离能逐渐减小,N原子的2p为半充满状态,较为稳定,第一电离能最大,第一电离能由大到小的顺序为N>O>S>Cu;蓝色沉淀氢氧化铜被氨水溶解时发生反应的离子方程式为Cu(OH)2 + 4NH3 =[Cu(NH3)4]2++2OH-,故答案为:N>O>S>Cu ;Cu(OH)2 + 4NH3 =[Cu(NH3)4]2++2...
The low-field susceptibility,1 specific heat,2 proton resonance,3 and magnetization isotherms4 of Cu(NO3)2 · 2.5H2O at low temperatures can be described approximately by a model in which the cupric ions are antiferromagnetically coupled in pairs. The members of a pair (S1 = S2 = \(\frac...
