Calculate the rate of diffusion (in & mole/m s) of acetic acid across a film of non-diffusing water solution i mum thick at 17 c when the concentrations on opposite sides of she glm are 9 and 3 wt % acid, respectively. the diffusivity of acetic acid in the solution is 47 10inchis) given that, the densities of the 9 wtand 3 w % solution are 1012 and 1003 2 kgmrespectively.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

l dont know l am s sorry

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.
