Pepsin hydrolyzes proteins in the stomach. the ph in the stomach is 2, and the optimum ph for pepsin is 2. what do you think would happen to the activity of pepsin when it reaches the small intestine, where the ph is 8? explain why.

i wish i could but this one is weird give me abc and i can solve it.

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.
