A 25.121 mg sample of a chemical known to contain only carbon, hydrogen, sulfur, and oxygen is put into a combustion analysis apparatus, yielding 44.751 mg of carbon dioxide and 18.319 mg of water. In another experiment, 32.443 mg of the compound is reacted with excess oxygen to produce 14.02 mg of sulfur dioxide. Add subscripts to the formula provided to correctly identify the empirical formula of this compound. Do not change the order of the elements.

empirical formula:
CHSO

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible?
