What is the standard cell notation of a galvanic cell made with zinc and gold? A. Zn(s) | Zn2+(aq) || Aut(aq) | Au(s)
B. Zn2+(aq) | Zn(s) || Au(s)| Aut(aq)
C. Au+(aq) | Au(s) || Zn(s) | Zn2+(aq)
D. Au(s) | Au+(aq) || Zn2+(aq) | Zn(s)

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

One does not belong why? ice, gold ,wood ,diamond and table salt

What can be found in the ionosphere
