Document Summary
[p + ] [v nb] = nrt ln = ( ) 2 nh3(g) + 2 o2(g) n2o(g) + 3 h2o(l) h = 6. 626 x 10 34 j s c = 3. 00 x 108 m/s. A hydrogen atom emits with energy of 276 kj/mol when an electron makes a transition from the fifth energy level. Determine what level the electron ended in. level 2. Arsenic, as as3+ (valence 4s2) and as3- (valence 4s2 and 4p6) Lead, pb pb2+ (valence 6s2) and pb4+ valence 5s2 5p6 and 5d10) Give the systematic (iupac) name for the following: a) Antimony (iii) chloride; indium chloride; chromium (iii) oxide. Give the chemical formula for the following: d) tin fluoride e) molybdenum(ii) phosphate. Silicon has a work function of 462 kj/mol. If you irradiate a silicon surface with photons having a wavelength of 153 nm, determine the kinetic energy of the electrons that will be emitted, in joules (per electron).
