For selenium trioxide, answer the following: e) determine formal charges to all atoms

f) does this structure that you drew have resonance? If so, draw all possible resonance structures. If not, explain why there are no resonance structures.

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.)
