3. Why is a rotting apple a reaction in which energy is neither absorbed nor released? The chemical energy in the reactants is much less than the chemical energy in the products.

The chemical energy in the reactants is much greater than the chemical energy in the products.

The chemical energy in the reactants is almost equal to the chemical energy in the products.​

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.
