Five grams of barium hydroxide is dumped into a beaker of water at 25 degrees Celsius and allowed to dissolve and come to equilibrium. What is the final concentration of hydroxide? (Hint 1: 5 grams is way too much to actually dissolve, so the amount 5 grams will not actually be used. Hint 2: for every barium ion that forms, two hydroxide ions form: use algebra.)

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.
