You test the pH of your first hot tub’s water. You discover that it’s pH is 8.1. 1. What do you need to do to get the hot-tub water back to an acceptable pH?

2. What specific substance might you use?

3. What type of chemical reaction could occur when
you add this substance?

4. What would the products of this reaction be?

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.
