The overall reaction in a commercial heat pack can be represented as how much heat is released when 4.40 moles of iron are reacted with excess ? heat = kj how much heat is released when 1.00 mole of is produced? heat = kj how much heat is released when 1.60 g iron is reacted with excess ? heat = kj how much heat is released when 11.8 g and 1.20 g are reacted? heat = kj

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.
