Given a balanced chemical equation and enthalpy of reaction, relate energy change to amount of reactant or product involved in a reaction.
Briefly comment on whether or not this experiment shows that you can successfully model the packing of atoms in a liquid by randomly packing
Draw the mechanism for each reaction you will do today. Pyridinium tribromide releases molecular bromine, so molecular bromine is the brominating agent.
