Mixing 25.0 ml of 1.2 m hclo4 and 25.0 ml of 1.1 m naoh were mixed. the temperature of the initial solution was 22.4 o
c. assuming a heat of neutralization of 55.8 kj/mol, what would the final temperature be if the specific heat for this solution is 4.032 j/g o ?

k

explanation:

k

sure im new too!

explanation:

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.
