2. Use the following equation: 2 C6H10 + 17 02 ---> 12
CO2 + 10 H2O

a) If I do this reaction with 35 grams of C6H10 , how many grams of
carbon dioxide will be formed?

b) If 45 grams of O2 was used, how many grams of carbon dioxide will be
formed?

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter  

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.
