A compound is 2.00% H by mass, 32.7% S by mass, and 65.3% O by mass. What is its chemical formula? To solve this problem, you will perform the following steps:

Assume 100.0 g of the compound.

Calculate the mass of each element in the sample.

Calculate the number of moles of each element present.

Calculate the mole ratio of elements present.

Write the empirical formula.

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.)
