Which two conditions can limit the usefulness of the kinetic-molecular theory in describing gas behavior? high pressure and low temperatures high pressure and medium temperatures low pressure and low temperatures low pressure and medium temperatures

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

the answer is barium and copper bromide
