The Kihabe Zn-Pb-V > (Cu-Ag-Ge) prospect is located at the boundary between Namibia and Botswana (Aha Hills, Ngamiland District) in a strongly deformed Proterozoic fold belt, corresponding to the NE extension of the Namibian Damara Orogen. The Kihabe prospect contains Zn-Pb resources of 14.4 million tonnes at 2.84% zinc equivalent, Ag resources of 3.3 million ounces, and notable V-Ge amounts 2012-04-24 2018-03-27 After heteroatoms doping (N, S, P, even transitional metal atoms), they also have potentials as the ORR electrocatalysts. 127 The discovery of N‐doped carbon nanotube (CNT) as ORR catalyst inspires a boom of researches toward nanocarbon based electrocatalysts, 128 their application in Zn–air batteries also spring up and much progress have been made.

Such a weapon is not known to have ever been built, tested, or used. 65 Zn is used as a tracer to study how alloys that contain zinc wear out, or the path and the role of zinc in organisms. When bombarded with alpha particles, the isotopes 72 Ge and 76 Ge will generate stable 75 As and 77 Se, releasing high energy electrons in the process. At least 27 radioisotopes have also been synthesized ranging in atomic mass from 58 to 89.

B. Arranging these substances in order of increasing melting points is straightforward, with one exception. We expect C 6 (CH 3) 6 to have the lowest melting point and Ge to have the highest melting Because Zn has a filled valence shell, it should not have a particularly high melting point, so a reasonable guess is C 6 (CH 3) 6 < Zn ~ RbI < Ge. The actual melting points are C 6 (CH 3 ) 6 , 166°C; Zn, 419°C; RbI, 642°C; and Ge, 938°C. Consider 72 Zn , 75 As and 74 Ge . These 3 species all have the same number of _____ .

The Kihabe prospect contains Zn-Pb resources of 14.4 million tonnes at 2.84% zinc equivalent, Ag resources of 3.3 million ounces, and notable V-Ge amounts, still not evaluated at a resource level.

However, the amount of elemental Zn in each salt varies. For example, Zn-sulfate contains about 23% elemental Zn; therefore, to have 50 mg of Zn, a 220 mg of Zn-sulfate tablet would be required for consumption.

All carbon atoms have 6 protons in the nucleus, but they can have either 6, 7, or 8 neutrons. Elements 72Zn, 75As, and 74Ge have the _____. A) same number of protons. B) same number of protons and electrons. C) same number of neutrons. D) same number of neutrons and electrons Your approach complicates the problem a lot. I think you should abandon it.
