A sample of chlorine gas contains 2.12 moles at -12.5 C and 0.972 atm. What volume will the gas occupy?

20 drops hope this

the dependant variable is spilled water

the independent is the heat

wher is the rest of the question

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.
