A postulate of the kinetic molecular theory is listed. Postulate: The average kinetic energy of gas molecules is related to the temperature of the gas.

Which of the following activities can be used to demonstrate the postulate?

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.)
