Consider the molecules H20, H2S. H2Se, and HzTe. Which do you expect to have the highest boiling
point, and why? (4 points)
KINH20, because it experiences hydrogen bonding.
OH, S, because it dissociates and forms ions.
H2Se, because it experiences ion-dipole forces.
H2Te, because it has the most electrons to form a dipole.

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 5.35 mol fe and 7.65 mol nio(oh) react?
