Presentation Transcript

  1. HOW TO BOIL WATER -a chemical approach You have been stranded in an abandoned ghost town that once housed a chemical factory. Having been there for three days, you have run out of supplies and desperately need drinking water. While wandering endlessly around, you notice a door open to the vacant factory. Inside you find a plethora of water containers. Knowing the water needs to be boiled first, you search the factory for a heat source. You hit the jackpot…a cabinet containing various hydrocarbons! But you must decide which will be the most efficient because you don’t know how long you are going to be stranded here and want to boil 100g of water at a time to ration the water. Ah, you recall freshman chemistry class and know that you need to calculate how much energy each hydrocarbon will give off when combusted. There is a problem however, you only have a limited supply of each hydrocarbon. IMMEX Prolog Chemical List Library Solve

  5. Molecular formulas Combustion Reaction Bond Energies Specific Heat of Water O2 Equations What is a Combustion Reaction? To refresh your memory from general chemistry back in college, a combustion reaction is a chemical reaction that proceeds with evolution of heat and usually a flame; most combustions involves reaction with oxygen EX. C6H14 CO2 + H2O + heat It is important to remember that some heat will be lost to the environment when doing a combustion reaction; e.g. Not all of the heat can be harvested for use.
