When 12.0 grams of the element carbon react with 4.00 grams of element hydrogen, natural gas is produced. there is no leftover carbon or hydrogen when these quantities are used. how much carbon and hydrogen would you need to make 100.0 grams of natural gas.

75g of Carbon and 25g of Hydrogen

Explanation: the ratio of carbon to hydrogen is 12:4

Total ratio = 16

Mass of carbon in the natural gas

= (12/16) x 100 = 75g

Mass of Hydrogen in the natural gas = (4/16) x 100 = 25g

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.
