Enthalpy and Thermochemistry Problem Set
In the video clip from George Gobel
you saw that it is possible to light a charcoal grill in about a
minute. If the grill is prepared using one 20 pound bag of
charcoal (primarily carbon) and two 1 gallon buckets of liquid
oxygen (the density of LOX (liquid oxygen) is 1142 kg/m3,
CRC Handbook of Chemistry and Physics.)
- Write a balanced chemical equation describing this
reaction.
- Determine the limiting reagent for this reaction.
- Calculate the mass of each product and any remaining
reactant.
- Calculate the amount of heat released by this reaction.
- If this heat is used to warm a 500 gallon tank of water
at 15 C, what is the final temperature?
- If this heat is used to warm 40 kg of ice at 200 K, what
is the final temperature?
