How much of a 36.0 g sample of Cs-137 will be left after 120 years?

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
