2SO_3(g) \leftrightharpoons 2SO_2(g) O_2(g)0.78 moles of SO_3 are placed in a 2 L container at 298K and allowed to come to equilibrium. If at equilibrium 0.20 moles of O_2(g) are found to be present in the container, what is the value of the equilibrium constant, Kc

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
