Harvey mixes two liquids. which observation of the new mixture most likely indicates a precipitate is forming?

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.)

What reaction is taking place? 02 + c3h8 = h20 + co2
