1424

Explanation:

Q=mco

Qis energy

M is mass

C is specific energy

O is temperature change

Substitute all the information you have in the equation then you will get the answer

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.
