Janice notices that the reaction rate increases if she heats the solution. explain why a)increasing the temperature decreases the energy. b)increasing the temperature increases the molecular motion. c)increasing the temperature reduces the collision frequency d)increasing the temperature divides the solubility of the solute

answer:

um i dont really knos i tried to answer it but i think its b

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
