the table shows the solubility of two substances in water at 20 °c.
solubility of substances
mass kg solubility of sodium chloride solubility of lead nitrate both per 100g
of water
100 l k
200 36 54
part 1: what will be the values of l and k for 100 kg of each substance?
part 2: explain your answer for part 1.

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.
