Answer: hydrogen molecules.
Explanation: in same temperature molecules have same average kinetic energy.
You can estimate it solving E = 3/2 kT = 1/2 mv². Constant k is Boltzmann constant.
Lighter molecule has greater speed
➜ <u>Oxyhaemoglobin</u>.
➜ <u>Carboxyhaemoglobin</u> and as carbonic acid (CO2 dissolved in blood plasma).
Two, most have to have two but if it has more then it has multiple
