When a 5.00 g 5.00 g sample of KCN KCN is dissolved in water in a calorimeter that has a total heat capacity of 1.95 kJ ⋅ K − 1 , 1.95 kJ⋅K−1, the temperature decreases by 0.460 K . 0.460 K. Calculate the molar heat of solution of KCN .

h let me think

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.
