Practice 3 (Work in groups if time; use equations at top of this page) 1) How many moles of P&O 10 are produced from 7.2 mol of phosphorus?
2)
How many moles of water do I need to produce 0.82 mol of H2SO3?
3)
How many moles of oxygen do I need to react with 0.355 mol Fes?

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.
