The diagram above shows the repeating groups of atoms that make up two samples. Will the properties of the two samples likely be the same or different?
(Examples of properties are smell, color, and the temperature at which a
substance melts.)

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.)
