If 3.4 moles of a gas occupies a volume of 0.0406 liters at 298 K, what is its pressure? (Show work to receive credit) A. 30,397 atm
B. 2,049 atm
OC. 0.023 atm

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
