20.(12分)(1)元素As与N同族。预测As的氢化物分子的空间结构为(2)NH4H2PO4中P的杂化轨道与O的2p轨道形成键。(3)预测As的氢化物的沸点比NH3的(填“高”或“低”),其判断理由是(4)苯胺(▱-NH_2) 与甲苯|1|-CH_3)的相对分子质量相近,但苯胺的熔点(-5.9℃)、沸点(184.4℃)分别高于甲苯的熔点(-95.0...
Here, the microscopic path of Al3+-ion conduction of NASICON-type(Al0.2Zr0.8)20/19Nb(PO4)3 oxide is identified by temperature-dependent neutron powder diffraction and aberration-corrected scanning transmission electron microscopy experiments.(Al0.2 Zr0.8)20/19 Nb(PO4)3 shows a rhombohedral ...
下列说法正确的是( )A.SiH4比CH4稳定B.O2-半径比F-的小C.P和As属于第VA元素,H3PO4酸性比H3AsO4的弱D.Li和K属于第IA族元素,K失电子能力比Li的强
