Write the reaction and the Ksp expressions for the following slightly soluble salts dissolving in water. A. Lead iodide (PbI2) B. Calcium iodate Ca(IO3)2 2. A student performed the titrations done in this experiment. The student pipetted 25 mL of saturated calcium hydroxide solution into a flask and then titrated it with 0.103 M HCl. It required 22.7 mL of HCl to reach the orange-red end point. Calc

Answer might be b. I think

b. 0.10 M Ob(NO3)2

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.
