3. aluminum will react with sulfuric acid in the following reaction. 2al(s) + 3h2so4() → al2(so4)3(aq) + 3h2(g) a. how many moles of h2so4 will react with 18 mol al? ans: 27 mol h2so4

a graduated cylinder.

explanation:

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.
