The ""size"" of an atom is sometimes defined by the radius of a sphere that contains 90% of the charge density of the electrons. Calculate the ""size"" of the hydrogen atom in its ground state according to this definition. (see below for useful integral; you do not need to fully solve for a numerical answer –you may leave in polynomial form. A guess and check approach will get you pretty close if you want to see the numerical answer.)

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall.
