For every 2 mole Mg we need 1 mole O2 ( based on the equation). since there is 4 mole Mg we need 2 mole O2. one mole O2 is 32 gram so 2 mole would be 64 grams.
Answer:
kinetic energy is directly proportional to the absolute temperature this is because when absolute temperature is increased it tends to cause more collision of the particles which hence increases kinetic energy of the particles .
since kinetic energy is the energy due to motion
