Discussion:

  • You can describe the reaction that took place in terms of enthalpy, by writing a fully balanced equation (and net ionic equation) for the reaction, as well as drawing an energy change diagram for the reaction, clearly indicating the measured quantity of heat energy change.
  • Is the reaction exothermic or endothermic? Explain this in terms of bonds breaking and forming
  • Discuss the method and set up of the experiment
  • Was the experiment accurate (calculate percentage error).
    |(theoretical-experimental)/(theoretical) | × 100%. The theoretical value is -55.84 kJ/mol. error from 0% to ≈30% is accurate.
  • Was the experiment reliable? (are results of each trial close to each other?) (only if applicable)
  • Was the experiment valid? (is it both reliable and accurate)
  • What can be done to improve the experiment? to improve reliability, validity, accuracy?

Conclusion: You can use this basic outline, to structure your conclusion, and expand it from there.

By investigating/measuring/using a....... it was determined that........ This is consistent/not consistent with the expected result/theory of...... due to/because of...........
