Document Summary

Information you may (or may not) nd useful. Avogadro"s number gas constant (r) gas constant (r) electron charge (e) electron mass. An electron has a wavelength of 1. 20 10 1 nm. What is the speed of the electron in (m/s)? v = h m = E = (4. 50 10 8 6. 022 1023) 6. 626 10 34 j s 3. 00 108 m/s. 4 points d a hydrogen atom is in state n = 2. E = 2. 18 10 18 j(cid:0) 1 1. Provide the systematic name or molecular formula for the following compounds: a (nh4)2cr2o7 : ammonium dichromate. N2o4 : dinitrogen tetroxide c mgco3 : magnesium carbonate d e ammonium phosphate : (nh4)3po4 sulfur hexa uoride: sf6. Answer: s2 c rank the following bonds from smallest to largest polarity: o-n, o-c, o-fe. Answer: o-n < o-c < o-fe d rank the following elements from smallest to largest ionization energy: mg, ca, sr.
