Tia has a sample of pure gold (Au). She weighed the sample and the result was 37.6 grams. Tia wants to determine the number of atoms in the sample. Calculate the number of atoms in 37.6 g of pure gold.

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.)
