1. Given the balanced equation: CzHs + 5 O2 CO2
H2O
a. What is the mass of CO2 forms when 95.6 g of propane, C3H8, burns? (286g CO2)

b. How many grams O2 is consumed in letter a ?

c. How many grams water is given off in letter a ?

d. If 11.4 g of carbon dioxide is produced, how much propane has been burned?

i think its 100

i hope this !

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.
