To determine the approximate mass of a small sherical shot of copper the following experiment is preformed: 125 pieces of shot are added to 7.9ml of water in a graduated cylinder and the volume becomes 8.3ml. The density of copper is 8.92 g/cm^3. Assuming that all the pieces of shot are the smae size what is the mass of a signle piece of shot?
What are the concentrations of HSO4-, SO42-, and H+ in a 0.255 M KHSO4 solution? (Hint: H2SO4 is a strong acid; Ka for HSO4- = 1.3 10-2.)
The effective nuclear charge, Zeff, for a valence electron can be approximated using the "core charge" of the atom, that is, the total charge of the nucleus and the inner (non-valence) electrons.
Write a balanced chemical equation for the neutralization reaction upon which this titration is based, and indicate clearly which atom is being protonated. Then, calculate the equilibrium constant for the neutralization reaction.
