Methane, a gas heavily associated with the natural gas industry, is a potent greenhouse gas. Consider the
combustion reaction below.
CH4(q) + 2O2(g) + CO2(g) + 2H2O(9)
Calculate the volume of O2(g) necessary for the complete combustion of 100 g of CH4(9) at 19.9 atm and
35.5°C.

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.
