Part 1. a chemist reacted 18.0 liters of f2 gas with naci in the laboratory to form ci2 gas naf. use the ideal gas law equation to determine the mass of naci that reacted with f2 at 290. k and 1.5 atm.
f2 + 2 naci > ci2 + 2naf
part 2. explain how you would determine the mass of sodium chloride that can react with the same volume of fluorine gas at stp.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
