Write the balanced equations for the following reactions: a. Iron metal and chlorine gas react to form solid iron(III) chloride. b. Solid aluminum carbonate decomposes to form solid aluminum oxide and carbon dioxide gas. c. Solid Magnesium reacts with aqueous silver nitrate to form solid silver and aqueous magnesium nitrate.

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.
