A student wants to identify the main component in a commercial liquid cleaner. She finds that 35.8 mL of the cleaner weights 28.1 g. of the following possibilities, which is the main component of the cleaner? Show your work. a. Chloroform, Density = 1.483 g/mL
b. Diethyl Ether, Denstiy = 0.714 g/mL
c. Isopropyl Alcohol, Density = 0.785 g/mL
d. Toluene, Density = 0.867 g/mL

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

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.
