Question
Little Johnny’s parents leave him alone with the babysitter while they go out for an amazing dinner at Ruan Thai
restaurant in Wheaton, Maryland. While the babysitter listens to music by Between the Buried and Me and texts her
friend, Johnny goes down to the basement and performs the thermite reaction that he read about—it was used to weld
railroad ties! How cool is that?!
2 Al(s) + Fe2O3(s) à 2 Fe(s) + Al2O3(s)
If he reacts 11.000 g aluminum with 19.000 g iron(III) oxide, will the iron he makes melt? (In other words, will the
heat produced be sufficient to raise the temperature of the iron he makes to its melting point of 1537oC?) Assume that
the iron absorbs only 60.0% of the heat produced. Assume the iron’s initial temperature is 17.22oC. The specific heatof iron is 0.450 J/goC. Do you think Johnny will get in trouble? [Hint: Find the final temperature of the iron and
compare to the melting point. Hint: The masses of both reactants are given. What kind of problem will you have to
do?]
