and carbon dioxide? *
C3H8 +502->4H2O + 3C02

A)3 mole CO2 / 5 mole C3H8

B)3 mole C3H8/4 mole CO2

C)3 mole CO2 / 1 mole C3H8

D)3 mole C3H8 / 1 mole CO2

C)3 mole CO2 / 1 mole C3H8

Explanation:

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.
