Pleas help me with this question, i was thinking it made methanoic acid but I’m not sure :/ Write a balanced equation for the following reaction. draw structural formulas of organic compounds
and name the organic product. Write no reaction if there is no reaction!

methanol + H2SO4 / K2Cr2O7 refluxing

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.
